Non Technical Summary
There are many acres of fruit crops in the North East of the USA, all of them are grown for the quality market, sadly some fruit doesn't reach that standard. The goal of the research proposed herein is to better understand the methods of improving spray deposition by reducing and controlling air volume and liquid volume as the canopy develops throughout the growing season. In particular I am interested in researching the inter-relationship between them and how sprayers may be modified to address the issues. Additionally research projects will be selected for their potential to make significant theoretical and practical advances in pesticide application technology. Traceability: 65% of grape production goes for fruit juice. Fruit juice production in New York is a MAJOR industry and a food scare will devastate an already fragile farming economy. Pesticides are a necessary part of fruit production and when chemicals are not applied properly, managers may be unaware of costly problems until it is too late to correct them. There is no traceability system from farm to processor for fruit, a major concern, particularly if there was to be a food quality scare such as the recent scares with food-borne diseases in vegetables, resulting in illness and death. We need a traceability system for all commodities. I propose to develop a fruit sprayer monitoring system to aid farm management and traceability of pesticide use in vineyards and orchards in New York. We will monitor and record the pesticide flow rate and location using flowmeters and GPS location devices and download them each day onto the office computer. We will record if spray was applied to each row, monitor if rows are missed or double dosed. This will be an aid to the management of sprayers, staff and for tracking pesticide use. Computerized pesticide records will provide data to help with traceability of apples and grapes from the grower to the processor to the bottle or store. If a food scare should develop, then immediate traceability will be available which will assure consumers of quality food from NY fruit growers. This project is very timely, as we must have methods of traceability in place before a pesticide residue scare breaks out in the fruit industry.

Goals / Objectives
Objectives: 1.Decrease the risk of environmental pollution by reducing drift. 2.Improve deposition within the canopy of fruit trees and grapevines. 3.Develop a precision sprayer which will automatically adjust air and liquid volume according to canopy density 4.Develop a system of monitoring spray use to provide traceability to processors, growers and consumers. Expected outputs - Improvement in deposition. Applying the correct amount of spray to the target will increase efficiency and result in better insect and disease control. Canopy monitoring techniques will reduce waste and therefore improve the budgets of the growers. - A precision sprayer. Precision is required if we are to apply the correct amount to an ever-changing canopy. -Traceability. Society requires more and more information on all the food processes. Processors of foods, e.g. apple juice and grape juice also require detailed pesticide records. An automatic data logging system will provide genuine application records and provide the consumer/processor with confidence in their food.

Project Methods
According to crop structure the total height of canopy will be divided into five sample areas (from bottom to top) and three layouts (both external and one internal). From every one of the fifteen sampling areas (5 heights x 3 depths) two or three representative leaves will be picked up and stored in a plastic bag. A total of 50 samples of leaves will be harvested prior to the field test in order to determine the leaf area. All those 50 leaves will be weighed and its surface determined using a scanner. The extraction of deposited tracer on leaves will be determined washing leaves into the bags by adding an exact quantity of washing liquid. Plastic bags containing leaves will be well shaken and leaves will remain in contact with the washing liquid for 30 minutes. After that a sample of this liquid will be collected and placed in a crystal tube. Concentration of tracer will be determined by using light absorption in a laboratory. Results will be expressed in terms of deposition by leaf surface (micrograms/cm2). Leaf surface of each sample will be calculated by weighting samples and using the previously obtained relation between weight and surface. Trials will be conducted, at three different crop stages in coincidence with flowering, pea size and version stages, and in at least two different varieties, both representatives of every area of work. A flow meter /data logging system will provide growers with accurate data on their application rate and location. GPS will provide location and Google maps provide a map for overlaying the data. Application information will be used to assist with traceability of product use, and application volumes. An automated, computer based system will eliminate the traditional manual data entry of today. In the next two growing seasons we will develop a canopy sensing system using infra-red and, or ultrasonics to measure canopy density. The sensor information will then be used adjust air volume (using the air louvre) and liquid volume (using banks of air-assisted nozzles) according to the canopy dimensions. We will conduct comparative field trials, using blocks of trees/vines with co-operating growers. Pesticides will be applied to blocks, based on the farmers own traditional methods, and other blocks will be treated using the precision sprayer to vary application rate and airflow. Both treatments will be compared in terms of biological efficacy (by measuring the level of control of disease and insects) and in terms of quality of applications by determining aspects as coverage on leaves, uniformity of distribution, losses on soil and capacity of penetration. Deposition on crop and losses on soil will be measured by adding into the tank a determined quantity of fluorescent tracer, Tartrazine. Concentration of tracer in the tank before and after spraying will be measured taking samples directly from the tank. Quality of applications will be measured by picking leaves from the top, middle and bottom part of the canopy and also at the inner and outer parts.

Target Audience:Farmers and fruit growers across the USA. The audiences were predominately the owners or managers of vineyards and orchards, although a growing number of growers are bringing their employees to the meetings and workshops/conferences. This is particularly important as a broader brush approach, particularly when sprayer operators are present,is a very usefulmethod of getting the research to a wider audience. Changes/Problems: Nothing Reported What opportunities for training and professional development has the project provided?The project has provided plenty of opportunities for growers to develop their knowledge of fruit crop spraying, from 30 minutes presentations to one-day workshops. For me, I have met plenty of growers and it is always a two-way conversation, so I have learned a lot from the industry. How have the results been disseminated to communities of interest?Information has been disseminated via academic journals and internet journals. Also via traditional conference and workshop presentations. ! webinar was conducted using the internet and this presentation has been posted for further instruction. What do you plan to do during the next reporting period to accomplish the goals? Nothing Reported

Impacts
What was accomplished under these goals? Under objectives 2-5 of the original goals I have conducted a number of farmer/fruit growers demonstrations and workshops during 2017. I conducted 6 extension meetings in New York, 1 in Texas and 1 in Iowa, 1 in Kentucky. # workshops were held overseas and 1 webinair was conducted. I also held 5 one-day workshops in New York.

More field trials, as the sprayer becomes more developed so we will wish to conduct more field trials to gather data.

Impacts
What was accomplished under these goals? We developed a completely automated sprayer which can adjust airflow and liquid flow in real time whilst travelling down the rows of apple trees or grapevines.The system uses ultrasonic sensors to monitor canopy volume and via a control system will adjust application volume or spray rate per acre via a series of nozzles or combination of nozzles. We are using the Lechler vario jet nozzles which are pneumatically controlled. We use three nozzles in a cluster which is sufficient for apple trees. We are using the same ultra sonic canopy sensor system to detect the canopy and then adjust the airflow by using the Cornell patented adjustalbe air louvre. Thios system is being used in grapevines, All developemnt was conducted in the lab at NYSAES, Geneva and field trials were carried out at NYSAES Geneva in the summer of 2013. We now have good solid data on year 1 of our project for both apple trees and grapevines. We have demonstrated the project to over 300 fruit growers who attended the fruit Field Days at NYSAES on August 1st 2013. I have also given a number of presentations at conferences both in USA and Europe, notably Spain. My post doctoral researcher, Jordi Llorens presented ap oster on the subject at the Precision Farmimng Conference in Lleida and won best poster award.

OUTPUTS: This project was approved on August 20 2012. At the time of writing, December 4, we have had approx. 3 months to conduct our research. On September 1, Dr Jordi Llorens Calveras joined my research group. Dr Llorens Calveras has joined us from the University Polytechnica Catalonia in Spain where his research has been based upon the use of electronic sensors for precision spraying. In fulfilling the objective 3 stated in the proposal, Development of a precision sprayer which will automatically adjust both air and liquid volume according to crop canopy. He created a list of electronic items which have been purchased. We are using a John Beam tower orchard sprayer for adjusting liquid flow. We are using a Berthoud S600 axial fan vineyard sprayer for the adjustable air flow. Both sprayers will use a single sensing system which will be transferred between the sprayers. Sensor items, circuit boards, data loggers, wireless transmitters and all wiring have been assembled in the past three months. We have use of a wet lab at Cornell and have just started the lab development phase. Objectives 1, 2, and 4 will follow as we progress to field trials in Spring 2013. PARTICIPANTS: Nothing significant to report during this reporting period. TARGET AUDIENCES: Nothing significant to report during this reporting period. PROJECT MODIFICATIONS: Nothing significant to report during this reporting period.

Impacts
At this early stage of 3 months into a project we have no outcomes to show other than the very early stages of a prototype sprayer.We are certainly on time with our projection to be conducting field trials in Spring 2013.

Progress 10/01/10 to 09/30/11

Outputs
OUTPUTS: We have continued our field trials measuring airflow within and through the canopy. As I wrote last year the answer is blowing in the wind and we have measured airflow through grapevines. We have found best spray deposition occurs when the airflow is reduced to a low volume and speed, particularly in early to mid season canopies. In early season there is such little canopy to intercept the spray, resulting in large clouds of drifting spray, this results in drift with poor deposition. Airflow can be adjusted using the Cornell air louvre described in previous reports or by adjusting the speed of the rotating fan. Besides improving deposition, the slower air speed reduces drift considerably, our trials in various size vine canopies and different varieties all show similar results. Extension meetings were held in vineyards in the Finger Lakes region, NY and Lake Erie region, NY as well as Vineland NJ. to demonstrate the improved deposition found by slowing down the airspeed. Over 100 growers attended twilight meetings where I demonstrated airflow with fluorescent tracer and black light, as described in last years report. Growers are still amazed as to how little spray actually hits the fruit, particularly when the fruit is large and has a greater boundary layer to prevent spray from settling. This is even more pronounced at higher airspeeds. We have developed the use of helium-filled soap bubbles released into a wind tunnel as a method of explaining to growers how airflow around a bunch of grapes or apple is determined by airspeed. We video the airflow and apply focused light to the bubbles, the results are very clear, the faster the airflow, the further away is the point of divergence and convergence. We then insert the video into powerpoint presentations to show growers exactly what is happening. This presentation has been shown throughout 2011 grower conference season and workshops. PARTICIPANTS: William Larzelere, Cornell University Prof Wayne Wilcox,Cornell University Nicole Landers, Cornell University Michael Morrabito, Cornell University Daren Simmons, farmer, Bluff Point, NY William Dalrymple, farmer, Ovid, NY Jim Quarrella, farmer, Vineland, NJ John Hardenburg, farmer, Portland, NY Rod Farrow, farmer,Waterport, NY TARGET AUDIENCES: Apple and grape growers across the northeast USA in particular and nationally in general terms.The growers are mainly full time, well established growers. A small number of new entrants to grape growing attended some of my mid west USA courses. I compiled a course handbook for the growers. PROJECT MODIFICATIONS: Nothing significant to report during this reporting period.

Impacts
Our field research on spray deposition and drift were evaluated in the 2011 season using the food dye, Tartrazine.. We continued to see increases in deposition of between 25-30% and drift was reduced considerably, around 75-80% using the air control systems. We saw huge improvements in deposition and reduction in drift in early to mid season canopies but little effect in full size canopies in late season. The reason for this variation is that there is more canopy to intercept the spray during full canopy growth. We continue to use a workshop to fabricate the air adjustment system and a laboratory for analysis of tracer for leaf deposition and drift analysis. In 2011 we moved into a new workshop with effective heating which hgas helped enormously. Personnel included a technician, a researcher and students helping with leaf collection and data analysis. Airflow research continues to create much interest in the apple and grape growing community of New York and PA. Better application of pesticides due to better targeting will result in better disease and insect control. Growers are able to reduce their pesticide use across the orchard or vineyard as a direct benefit of using the airflow adjusters. We are seeing a huge interest in the ability to change airflow, particularly in apple orchards where the tree canopies in modern orchard plantings are much narrower and smaller than traditional trees. Less spray drift over the canopy of trees and vines will result in less pollution and lowering the public profile of the spraying operation, this is so important as society visit farm shops, wineries and shop locally. Our projects have resulted in a lot of information which was extended at many meetings in 2011. For example 200 grape growers from across NY attended the pesticide update meeting in the Finger Lakes in May, 250 apple growers attended the Lake Ontario fruit tour in August. 200 grape juice producers in the Lake Erie region attended the PA Hort society Picnic where I demonstrated the air controller. We demonstrated all the methods described in this report. 6 twilight meetings were held in vineyards across the state to show fluorescent tracer deposition and airflow. I continued my grower conference talks across the USA, 45 talks per year. I also held 1 day grower workshops on vineyard and orchard spraying in WI, MO and IA.

OUTPUTS: Using the traditional airblast sprayer, so popular amongst the fruit growers we have continued our trials at measuring airflow within and through the canopy. The answer is blowing in the wind and we have measured airflow through the trees using 4 sonic anemometers mounted on a mast on a small trailer. The trailer is placed one side of a tree or vine, the sprayer the other side, this allows us to measure airflow through the canopy at various heights, either statically or dynamically. We have found best spray deposition occurs when the airflow is reduced to low speeds, as little as 3 mph leaving the trees or vines. In the dynamic mode, we can measure airflow for a row length, obtaining the average airflow for the varying canopy. Airflow can be adjusted using the Cornell air louvre described in last years' report or adjusting the speed of the rotating fan as in the case of the Croplands apple sprayer. Besides improving deposition the slower air speed reduces drift considerably. The major difficulty still remains in operating the anemometer trailer at the same speed as the sprayer in the dynamic test. 2 growers used the adjustable louvre on their vineyard sprayers for season-long trials - good deposition was found with little drift. Extension meetings were held in both apples and grapes to demonstrate the improved deposition found by slowing down the airspeed, growers attended twilight meetings where I demonstrated airflow with fluorescent tracer and blacklight then each grower went home with a kit comprising 2 bags of tracer dye and a small blacklight and brochure to test their own sprayer. The Botrytis project with a second tank and manifold continued with more trials with the cooperating grape grower, Hazlitts 1853, results still indicate acceptable control with great promise for reduced rates. The focus sprayer offers improvement for insect control, notably grape berry moth and results indicate a successful field trial. The trial using infra red sensors to detect absence or presence and height of grapevine canopy continued in early to mid season. The above trials were reported to growers at workshops, conferences and field days across the region. PARTICIPANTS: PARTICIPANTS: Brad Muise, post doc researcher, William Larzelere, technician, Jizhong Zhou, PhD student and Michael Morabito, summer student. The students improved their knowledge of applied research and field engineering. Co-operating growers include Mr G. Davey of Kast Farms. Rod Farrow of Lamont Fruit Farms and John Santos of Hazlitt 1853, William Dalrymple of Ovid and Daren Simmons of Bluff Point. TARGET AUDIENCES: Primarily apple and grape growers from New York state, but engineers and viticulturalists from all over the USA attended some of the extension meetings. Growers talks were held across the USA, see publications list for a few of them. PROJECT MODIFICATIONS: Not relevant to this project.

Impacts
Our designs were evaluated in the 2010 season using a fluorescent tracer, Pyranine and the food dye, Tartrazine.. We continued to see increases in deposition of between 25-30% and drift was reduced considerably, around 75-80% using the air control systems. The infra red sensor sprayer reduced spray use by 40% in the first early application of the season, in mid season, we saw savings of 18% in late June in the var. Vignoles. Little savings were seen once full canopy was reached. Resources used include the use of a workshop to fabricate the air adjustment system and a laboratory for analysis of tracer for leaf deposition and drift analysis. Personnel included a post doctoral researcher, technician and students helping with leaf collection and data analysis. Durand Wayland, a sprayer manufacturer is going to commercialize the air louvre. Airflow research continues to create much interest in the apple and grape growing community of New York and PA. Better application of pesticides due to better targeting will result in better disease and insect control. Growers are able to reduce their pesticide use across the orchard or vineyard as a direct benefit of using the airflow adjusters or the infra-red sensors. The tank rinsing development will help reduce environmental pollution, in particular point source pollution. Less spray drift over the canopy of trees and vine will result in less pollution and lowering the public profile of the spraying operation. Information was extended at many meetings in 2010. For example 180 grape growers from across NY attended the pesticide update meeting in the Finger Lakes in May, 300 apple growers attended a field day in Geneva, including members of the Dwarf Tree Fruit Association from all 4over the world. 50 grape juice producers in the Lake Erie region attended a twilight meeting. We demonstrated all the methods described in this report. We also conducted a similar demonstration to members of the North East group of ASABE (ag engineers) and the ASEV (viticulturalists) from all over the USA. 4 twilight meetings were held, 2 in apples and 2 in grapes across the state to show fluorescent tracer deposition and airflow. I continued my grower conference talks across the USA, 45 talks per year.

OUTPUTS: The traditional airblast sprayer still remains very popular in the apple and grape growing regions of NY. This past year we have continued our airflow development project. Using adjustable airflow and air direction devices, we are able to demonstrate a number of important effects to the spray plume. Closing down the air outlet allows us to minimize drift and keep the spray plume in the canopy, thus improving deposition within the canopy. Initial trials were conducted in var. Vignoles and show marked improvement in deposition and reduced drift. We will continue with our trials in 2010 season. A patent application was filed, via Cornell University, Ithaca in November 2009 for the adjustable airflow device, Application No. 61/263,630. We also conducted similar trial work in apple trees, var. Fortune, again results are very promising. We demonstrated this device to growers in an early season meeting in the Finger Lakes region. The project on tank rinsing is nearing completion. We carried out demonstrations again this season to various grower meetings. The Botrytis project with a second tank and manifold, gained momentum, we conducted more trials with a cooperating grape grower, Hazlitts 1853, results to date indicate acceptable control with great promise for reduced rates. The focus sprayer offers improvement for insect control, notably grape berry moth and early results indicate a successful field trial. An inexpensive sensor sprayer using infra red sensors to detect absence or presence and height of grapevine canopy was also developed, it was fitted to an airblast sprayer and used in grapevines and showed a good reduction in spray use in the first spray of the season in var. Vignoles. The above trials were reported to growers at workshops, conferences and field days across the region. PARTICIPANTS: Brad Muise, post doc researcher, William Larzelere, technician, Caitlin Leone and George Moraru, summer students. Caitlin just graduated from William Smith College in Chemistry, George is a student in aeronautical engineering in RPI, Albany. The summer students improved their knowledge of applied research and field engineering. Co-operating growers include Mr G. Davey of Kast Farms. Rod Farrow of Lamont Fruit Farms and John Santos of Hazlitt 1853 TARGET AUDIENCES: Apple and grape growers of the North East of the USA and in particular the states of NY and PA and NJ. Field meetings were held in May with the Finger Lakes grape growers, July with the MA fruit growers. Conference presentations were made over the USA. PROJECT MODIFICATIONS: Not relevant to this project.

Impacts
Our designs were evaluated in the 2009 season using a fluorescent tracer. We continued to see increases in deposition of between 25-30% and drift was reduced considerably, around 75-80% using air control systems. The infra red sensor sprayer reduced spray use by 40% in the first early application of the season, in mid season, we saw savings of 18% in mid season and then little savings once full canopy was reached. Resources used include the use of a workshop to fabricate the air adjustment system and a laboratory for analysis of tracer for leaf deposition and drift analysis. Personnel included a post doctoral researcher, technician and a summer students helping with leaf collection and data analysis. A number of growers and one sprayer manufacturer are very interested in making their own airflow adjustment system. Airflow research continues to create much interest in the apple and grape growing community of New York and PA as well as amongst the sprayer manufacturers. The economic impact will mean better application of pesticides due to better targeting. Growers are able to reduce their pesticide use across the orchard or vineyard as a direct benefit of using the airflow adjusters.

Less spray drift over the canopy of trees and vine will result in less pollution and lowering the public profile of spraying. Information was extended at many meetings in 2009. For example 160 grape growers from across NY attended the pesticide update meeting in May, 150 apple growers attended a field day in Massachusetts. I continued my grower talks across the North East USA, some dozen talks, plus others across the USA. I also continued with 6 in-depth courses on fruit spraying across the North East.

OUTPUTS: The traditional airblast sprayer remains very popular in the apple and grape growing regions of NY. We continue to design methods of adjusting airflow and air direction on a grape canopy sprayer. This year we developed an adjustable slide using an electric actuator, which limits airflow particularly in early canopies so that air doesn't blow right through the vine canopy. We continue to test a pair of air deflectors which direct the airstream and the spray horizontally into the canopy, rather than the traditional design which is to blow the air upwards and outwards. We built a tank washing unit on the top of an airblast sprayer which allows the operator to rinse the inside of the tank using rotating nozzles without using a hose pipe. This reduces potential operator contamination. We showed this at 5 venues this season. We also developed a second sprayline for Botrytis control in grapevines, this system uses a second tank on the sprayer and allows us to apply a canopy spray as well as a targeted fruit zone spray. PARTICIPANTS: Participants: William French and Stephanie Czajkowski were employed as summer students. William Larzelere also helped and is now my technician.William is a sophomore at Virginia State and is studying mechanical engineering so his summer was very useful to him. Stephanie just graduated from William Smith in chemistry and ran our spray lab equipment for analysis. Collaborators inclue William Dalrymple and Mike Jordan, grape growers and Ned Morgan and Rod Farrow, apple growers. TARGET AUDIENCES: Target audiences: Apple and grape growers of the North East of the USA and in particular the states of NY and PA and NJ. Field meetings were held in May with the Finger Lakes grape growers, July with the Lake Ontario fruit growers and the end of July with all NY grape growers at Dresden NY. Extension demonstrations were held in Biglerville, PA and Rutgers, NJ. PROJECT MODIFICATIONS: Nothing significant to report during this reporting period.

Impacts
Our designs were evaluated in the 2008 season using a fluorescent tracer. We saw increases in deposition of between 25-30% and drift was reduced considerably, around 75-80% using air control systems. Trials, using ai nozzles fitted to an airblast sprayer in an apple orchard proved to be physically and biologically successful. Drift was reduced by up to 50% with no change in biological efficacy. All projects have resulted in better deposition within the canopy (botrytis sprayer) and have reduced drift considerably (airflow adjustment and ai nozzles). Resources include the use of a workshop to fabricate the deflectors and a laboratory for analysis of tracer. Personnel included a technician and a summer students helping with leaf collection and data analysis. A number of growers are very interested in making their own airflow adjustment system. Airflow research continues to create much interest in the apple and grape growing community of New York and PA. The economic impact will mean better application of pesticides due to better targeting. Growers are able to reduce their pesticide use across the orchard or vineyard as a direct benefit of using the deflectors. The environmental impact to date, is less drift over the canopy of the trees and vines, less pollution and lowering of the public profile of spraying. 200 grape growers from across NY and PA attended the vineyard equipment demonstration of sprayers in Dresden. 150 apple growers attended a field day in Biglerville. We continued with our series of 3 demonstrations of the sensor sprayers in Orleans Co. with orchard growers in attendance.

OUTPUTS: The airblast sprayer is very popular in the apple and grape regions of NY. We designed a number of methods of adjusting the airflow and air direction according to canopy size and air volume requirements. Two methods, one an adjustable deflector on top of the sprayer to direct air into the canopy as the grower drives along a contour on a hillside,keeps the air moving into the canopy rather than spraying over the top of the row and polluting the environment with pesticides. A second development was the control of airflow using a flap or louver system, this limits airflow, particularly in early canopies so that air doesn't blow right through the tree or vine canopy. We also designed a pair of air deflectors which direct the airstream and the spray horizontally into the canopy, rather than the traditional design which is to blow the air upwards and outwards. PARTICIPANTS: Andy Joy was employed as the summer student and is an ag engineering student at SUNY Cobleskill and this project was regarded as an important part of his internship. Bruce Wadhams was my technician who supervised field trials and data analysis. TARGET AUDIENCES: Apple and grape growers of the North East of the USA and in particular the states of NY and PA

Impacts
Our designs were evaluated in the 2007 season using a fluorescent tracer. We increased deposition between 25-30% and drift was reduced considerably, around 75-80%. The air induction nozzle trials, fitted to the airblast sprayers proved to be physically and biologically successful. Drift was reduced by upto 50% with no change in biological efficacy. Both projects have resulted in better depostion within the canopy and have reduced drift considerably. Resources include the use of a workshop to fabricate the deflector and a laboratory for analysis of tracer. Personnel included a technician and a summer student helping weith leaf collection and data analysis. A number of growers are very interested in the deflectors and are making their own, airflow adjustment continues to create much interest in the apple and grape growing community of New York and PA. The economic impact will mean better application of pesticides due to better targeting. Growers are able to reduce their pesticide use across the orchard or vineyard as a direct benefit of using the deflectors. The environmental impact to date, is less drift over the canopy of the trees and vines, less pollution and lowering of the public profile of spraying. 400 growers across NY and PA have seen the deflectors at extension demonstrations in 2007.The largest gathering was at the fruit field day at Geneva in the summer. A series of 5 deomnstrations occurred in Orleans Co. orchards with growers in attendance. I presented information on their design to the Great Lakes fruit workers meeting, Niagara on the Lake, November 2007, so the information will cascade via the extension network in surrounding states.

Progress 01/01/06 to 12/31/06

Outputs
In the growing season of 2006 we concentrated on two major thrusts. The development of two patternators which growers can build themselves and the development of air deflectors for the Kinkelder airblast sprayers. In the 2005 report I mentioned the success of the MIBO vertical patternator but one problem is it is very expensive ($5000) for growers to purchase, although it clearly shows how to adjust the sprayer. We designed and developed two distinct patternators, both based on easily obtainable local materials. One is based on window fly screens, the other on plastic elbows. The patternators were tested and gave very comparable results to the MIBO. We have demonstrated them at 5 extension meetings throughout the summer and received good reviews. A number of growers have built these systems for less than $500. Both sets of plans and build lists are available free from the author. The patternators show growers how they can alter nozzle orientation to aim the liquid spray into the airstream, to counteract the airblast. The Kinkelder sprayer is very popular in the Lake Erie grape region - surveys suggest upto 175 sprayers exist there. Unfortunately this design of sprayer is very old, (around 30 years) and the grape juice industry has little money to invest in new technology. We designed a pair of air deflectors which will dirct the airstream and the spray horizontally into the canopy, rather than the traditional design which is to blow the air upwards and outwards. Our designs were evaluated in late 2005 so in the 2006 season three cooperating growers kindly agreed to fit a deflector on each of their machines and we evaluated them over the season. Using a fluorescent tracer, we found deposition increased between 25-30 percent and drift reduced considerably, around 75-80 percent. We held an extension field day to show the growers and they were very pleased with them. In our biological inspection, there was significantly less foliar powdery mildew with the new design than with the traditional head. There was no difference between sprayers for cluster powdery mildew or phomopsis. The three growers will use the new deflectors next season, albeit slightly stronger than our research designs! The project is going well, we are gaining a lot of information in this important area of pesticide application technology.

Impacts
The use of the vertical patternators continues to create much interest in the apple and grape growing community of New York and PA. The economic impact will mean better application of pesticides due to better targeting. Some growers are able to reduce their pesticide use by 20 percent across the orchard or vineyard as a direct benefit of using the patternator. The new self-build patternators will allow many growers to build their own or a small group build one to share. The environmental impact to date, is less drift over the canopy of the trees and vines, less pollution and lowering of the public profile of spraying. 500 growers across NY and PA have seen the patternator at extension demonstrations in 2006, from Long island to North east PA. I also demonstrated them in CT and Va. I presented information on their design to the Great Lakes fruit workers meeting, Ithaca, November 2006, so the information will cascade via the extension network in surrounding states.

Typical farmers settings on airblast sprayers are creating a lot of drift over and above the target due to traditional settings of the nozzles, i.e pointing radially outwards around the outlet of the airblast. Using the MIBO vertical patternator to conduct trials on deposition, we have found in the 58 sprayers tested that frequently the overspray can be as high as 30 percent. Growers must alter nozzle orientation to aim the liquid spray into the airblast, to counteract the upwards or downwards movement of the air blast. Changing the airfllow characteristics via air restrictors (doughnuts), an infinitley variable hydraulic motor drive to the fan or just shutting down tractor PTO/fan speed reduces drift considerably. On an AgTech sprayer we reduced PTO speed by 25 percent and reducded drift by 75 percent in an apple orchard trial. Airflow measurements using a GILL sonic anemometer show us how alterations in the design of the sprayer result in variations to the air stream. A new deflector design was created and tested for the Kinkelder sprayer, a typical sprayer in the Lake Erie grape belt. Air trials were conducted at NYSAES, Geneva, NY and next year we hope to conduct vineyard trials in Western NY and PA. The MIBO vertical patternator was bought to conduct research trials on deposition, this device shows how important little changes in direction alter the spray pattern considerably and is so useful as an extension tool for showing nozzle orientation to growers, it is rather expensive. In 2006 we intend to build an inexpensive, simple system and compare it to the MIBO. If successful growers will be able to build their own from local materials. The project is going well, we are gaining a lot of information in this important area of pesticide application technology.

Impacts
The use of the vertical patternator has created much interest in the apple and grape growing community of New York and PA. The economic impact will mean better application of pesticides due to better targeting. Some growers are able to reduce their pesticide use by 20 percent across the orchard or vineyard as a direct benefit of using the patternator. The environmental impact to date, is less drift over the canopy of the trees and vines, less pollution and lowering of the public profile of spraying. 530 growers across NY and PA have seen the patternator at extension demonstrations and a similar number have seen it in powerpoint video clips across the USA at conference presentations.

Outputs
In the growing season of 2004 we tested 24 airblast sprayers approx. a) The patternator results indicate the vertical spray pattern in relation to fan speed, air volume and nozzle orientation. By adjusting nozzle orientation, we can improve the distribution between sides of the sprayer. Further adjustment to the orientation of the nozzles allows us to further correct the inbalance caused by the upstroke/downstroke rotation of the fan and the subsequent airflow. We can also adjust nozzles to prevent over-spray above the canopy. Matching nozzle output/orientation to the canopy shape is also possible. b) All the pressure gauges we tested were in a satisfactory condition, less than 10 percent inaccurate. This is extremely good and some of the gauges were 10-12 years old! One gauge was impossible to remove without risk of stripping the threads in the brass cap. c) Pump flow is an indicator of pump wear and needs to be taken over a period of years. All pumps tested were over 85 percent of the rated output. Nozzle output was extremely variable; some nozzles were delivering correctly, many others were not. Frequently incorrect nozzles were fitted. The test was an eye-opener for all who experienced it. Growers were frequently amazed at seeing the in-balance of liquid between the left and right side of the sprayer. Simply adjusting nozzle orientation to shift the spray pattern was a simple remedy. What is the correct pattern required for optimum biological control remains the unanswered question, with each of the cooperating growers having their own point of view. We need to conduct trials with adjustment in nozzle output and orientation to match different canopy shapes, heights and sprayers The pressure gauge results were far better than anticipated. Surveys in other states had indicated this would be a major problem but in fact we were pleasantly surprised. Pump output will need to be monitored over a longer period to show any variability. The results indicate how rugged diaphragm pumps can be. Nozzle output was as suspected! Nozzles are so inexpensive in relation to the cost of the product being applied, yet remain the Cinderella of maintenance. On some of the sprayers the nozzles were perfect, attention to detail and in fact a degree of pride in having the correct output. In other tests the growers need to change nozzles more frequently and to have a number of spares available. In collaboration with extension educators in the regional fruit teams, we invited growers in the surrounding to attend a demonstration following a test. The testing procedure was repeated in front of the assembled growers and allowed a greater opportunity to develop the theme of good spraying practice. The tests certainly gave everyone food for thought. Defining the optimum spray patterns for insect/disease control and effective application of growth regulators should be carried out. Variables include vine and tree canopy shape, row width etc and sprayer fan size, air volume/speed and outlet shape. Field trials with biologists, horticulturalists and engineers should be conducted.

Impacts
The use of the MIBO vertical patternator has created much interest in the fruit growing community of New York and PA. The economic impact will mean better application of pesticides due to better targeting; a direct benefit of using the patternator. The environmental impact to date, is less drift over the canopy of the trees and vines, less pollution and lowering of the public profile of spraying. The changes in airflow will help promote these challenges next season.

Progress 01/01/03 to 12/31/03

Outputs
One season of field trials have been conducted on grapes to consider airflow, whilst it is early days, there is evidence to show that adjustments to airflow on the airblast sprayer make a major impact on reducing spray drift. A series of wooden doughnut have been created to reduce airflow. Airflow measurements using a GILL sonic anemometer show us how alterations in the design of the sprayer result in variations to the air stream. A new deflector design for next years field trials is currently undergoing air trials at NYSAES, Geneva, NY. Nozzle angle on the airblast sprayer is critical if spray is to hit the target. A MIBO vertical patternator was bought to conduct trials on deposition. This device shows how important little changes in direction alter the spray pattern considerably. Early indications are that this will be a most useful machine for demonstrating research to the growers. Canopy size was measured using a novel approach. The recycling return hose on a LIPCO tunnel sprayer provided data on the growing canopy as the season progresses. Trials were conducted in 2 commercial vineyards and will be repeated next season. Concord, Cabernet Franc and Riesling varieties were used in the trials. Overall it is very early days, but, the use of good scientific equipment will allow us to make rapid developments in this important area of pesticide application technology.

Impacts
The use of the MIBO vertical patternator has created much interest in the grape growing community of New York and PA. The economic impact will mean better application of pesticides due to better targeting; a direct benefit of using the patternator. The environmental impact to date, is less drift over the canopy of the vines, less pollution and lowering of the public profile of spraying. The changes in airflow will help promote these challenges next season.
