What was accomplished under these goals?
Coordination: The coordinator successfully managed funding for the IPM program. In 2014 the coordinator represented the IPM program in 35 speaking engagements. The coordinator supervised one graduate student who graduated with an MS degree. Evaluations were conducted for three IPM programs. The IPM Coordinator serves on the Sustainable Agricultural Advisory Committee and the Oklahoma Certified Crops Advisors Executive Committee. The coordinator served as chair the IPM Targeted Initiative Committee and attended the SERA003 committee. The coordinator also served on the SIPM Advisory Committee. Agronomic Crops: We completed a survey of Hessian fly emergence in 2014 using H fly pheromones. Data was collected for two years. We showed that we generally have two emergence peaks per growing season, with the spring emergence occurring over a two-month period. We also showed that there is no correlation between H fly emergence and subsequent infestation. These results demonstrate the utility of using resistant varieties, such as 'Duster' or 'Gallagher' in situations where production practices increase the threat of an economic infestation. Since 'Duster' and 'Gallagher' are planted on nearly 20% of the 4 million acres planted in 2014, we can estimate that planting those varieties on 2% of the acres that could be affected by Hessian fly that resulted in saving 20% yield loss, planting those varieties provided an economic benefit of $900,000.00. These results were presented at two field variety trial meetings in 2014. Our program evaluation specialist left employment and did not develop an evaluation tool for wheat growers. Oklahoma cotton producers suffered a complete crop loss due to drought. PI's developed information to assist growers in planning for a change in production based on the continued drought and unavailability of irrigation water. Canola continues to be used as an alternative rotational crop. Information on canola insect management was delivered to 14 field days and two Canola 101 programs, reaching nearly 400 growers. Canola was planted on nearly 250,000 acres, but only 190,000 were harvested due to extended drought. Little insect pressure was noted in 2013-2014. A new weed scientist faculty member was hired and has revived the resistant weed program. The sugarcane aphid was found in 15 counties in Oklahoma in 2014. Results of an insecticide trial indicated that a timely application insecticide for sugarcane control provided an average of 19 bushel/acre yield savings. Nearly 300,000 acres of sorghum was planted in Oklahoma in 2014. Assuming 5% of the acres were infested with sugarcane aphid and timely applications were made, our timely news releases resulted in $980,000.00 in yield savings. for sorghum growers. Low-income housing residents increased their knowledge of bedbugs and how they could personally reduce infestations by 30%. Master Gardeners received advanced "Train the Trainer training in IPM through a 2 session workshop, and results of a pre-post self-assessment survey showed that participants increased their knowledge of IPM, displayed a change in attitude regarding principles of IPM regarding cost, feasability and difficulty of implementation, and increased their skill set with regard to implementing and providing training to other stakeholders regarding IPM in the landscape. Surveys of Counties that are quarrantined for Red Imported Fire ants for establishment of phorid flies revealed that they have established in at least 3 counties. Surveys of counties for Diorhabda beetles for biocontorl of Tamarix (saltcedar) revealed that they have established in 17 counties.

Target Audience: Master Gardeners Wheat Producers Canola Producers Public Housing Authorities Public Housing residents County Extension educators Cattle Ranchers Oklahoma Botanical Garden volunteers general public Changes/Problems: We have dropped our plans to work with School IPM. School IPM is a totally voluntary program for public schools and our attempts to work with a selected school has met with resistance, primarily due to lack of funding and lack of sustained FTEs available from OSU that can be devoted to the program emphasis area. Schools identified other issues that are deemed more pressing. Two collaborators have left OSU. The positions (Pesticide Education Coordinator, which was involved with the School IPM program Emphasis Area and Weed scientist, which was a critical contact for screening herbicide resistant weeds were recently replaced. What opportunities for training and professional development has the project provided? In-service training provided to county educators on bedbug for 40 county educators. How have the results been disseminated to communities of interest? Workshops, field days, professional meetings, video, newsletters. What do you plan to do during the next reporting period to accomplish the goals? WE plant to finish the IPM program, and evaluate each ProgramEmphasis area, except for the School IPM project.
Impacts
What was accomplished under these goals?
OSU’s winter wheat variety “Duster” is the #1 variety planted in Oklahoma in 2012-13 with more than 1.1 million acres planted. “Gallagher” was released in 2012 and was planted in 11,200 acres in 2012-2013 Both are resistant to Hessian fly. Oklahoma produced more than 115 million bushels of wheat worth $619 million. Hessian fly resistant wheat varieties generated nearly $123 million in production. Of the acres planted to Duster, 5% or 55,000 acres were planted in areas where Hessian fly was a serious problem, resulting in an estimated $1.8 million in yield savings. Canola is an increasingly important rotation crop. It serves to help alleviate grassy weed problems that have developed from continuous production of winter wheat. Canola acreage increased to 250,000 acres in 2012-13 and 215,000 acres were harvested. Average yield was approximately 28 bushels per acre, meaning this crop contributed ca. $42 million to Oklahoma’s agriculture economy. Continued results of research conducted on the impact of diamondback moth suggest that timely control could potentially result in ca. $1 million in yield savings. Results of the timely reporting of insect activity in cotton allowed cotton producers to correct pest problems on more than 50,000 acres, resulting in a yield savings of nearly $1.7 million. The cotton crop in Oklahoma was a disaster. Since 2009, five herbicide-resistant weed species have been confirmed in Oklahoma and are spread throughout much of the state. Screening ceased in 2011 when our weed scientist cooperator resigned to take a job with industry. Results to date for documented herbicide resistant weeds indicate that • ALS-resistant Italian ryegrass on (estimated) 500,000 to 750,000 acres, documented in 17 counties • ALS-resistant cheat on (estimated) 500 acres, documented in three counties • Glyphosate-resistant marestail on (estimated) 500,000 to 750,000 acres, documented in nine counties • Glyphosate-resistant waterhemp on (estimated) 100,000 acres, documented in six counties • Atrazine-resistant Palmer amaranth on (estimated) 50 acres, documented in one county Because there are limited herbicide options to control ALS-resistant grass weeds in wheat, this information provides an important reason to practice crop rotation to more effectively manage weeds in winter wheat. Most wheat producers have switched to using ACCase-inhibitor herbicides to control Italian ryegrass. Glyphosate-resistant marestail and waterhemp were common in no-till fields of cotton and soybean throughout Oklahoma. The screening discovered a population of triazine-resistant Palmer amaranth. While atrazine is effective and commonly used, over-reliance on this herbicide and lack of rotation will ensure that atrazine-resistance will increase in the future. ANIMAL SYSTEMS: Results of an analysis of alternative management strategies for litter beetles suggest that ca. $7000 per house/year could be saved in reduced insecticide costs by using a combination of windrowing with insecticide applications. There are approximately 2379 poultry houses in Oklahoma, so the potential impact could reach $16 million in annual savings through reduced costs from fewer insecticide applications. Preliminary results of phorid fly trapping has not yielded any positive results. Sampling will continue in 2014. A released biological control agent for Tamarix spp. (saltcedar) was discovered in Oklahoma in 2012 and 2013. It has established in 17 counties in Oklahoma. IPM TRAINING FOR CONSUMER/URBAN ENVIRONMENTS: We have developed an assessment tools to measure learning of OBGA ambassadors and Master Gardeners that will participate in an advanced Master Gardener IPM workshop scheduled for 2014. Oklahoma Gardening viewership is 200,000. YouTube viewership of the series averages 350 per topic. IPM TRAINING AND IMPLEMENTATION IN SCHOOLS Nothing to report. IPM IN PUBLIC HEALTH: We provided training to over 200 low-income housing residents. We measured learning and adoption of Bed Bug Management Practices through use of a tool developed by our assessment specialist. Residents increased their knowledge of bedbugs and their management by 30%.

OUTPUTS: OUTPUTS: 2011/09 TO 2012/08 In 2011, IPM Oklahoma! conducts programs in 5 program emphasis areas. COORDINATION: The IPM Coordinator will be chairing the next SERA003 meeting in Baton Rouge LA, Mar, 2013. He serves on several advisory committees and provided 33 presentations and wrote 14 articles on topics related to IPM. The coordinator is using Twitter and wrote 25 tweets and is followed by 83 followers. The updated IPM Oklahoma! website will be launched by Sept. 1, 2012. IPM IMPLEMENTATION OF AGRONOMIC CROPS; A Pest Management Strategic Plan for Winter Wheat will be published by Oct 2012. Pheromone lures were used to monitor Hessian fly emergence during the 2011-2012 growing season. OSU's Duster became the second most grown wheat variety in OK and Gallagher was released in 2011-12; both are resistant to Hessian fly. While we still provided timely insect activity reports, we had an historic drought that almost completely eliminated Oklahoma's cotton crop. Since 2009, Dr. Joe Armstrong has given 20 presentations to more than 1900 stakeholders on herbicide resistance management. He has also provided information to the International Survey of Herbicide Resistant Weeds website (www.weedscience.org) regarding the distribution of herbicide resistant weeds in Oklahoma. IPM Oklahoma participated in a multi-state pheromone trapping program for fall armyworm coordinated by the University of Georgia. IPM IMPLEMENTATION OF ANIMAL SYSTEMS: Dr. Justin Talley conducted a results demonstration for litter beetle management at 2 poultry facilities in eastern Oklahoma. Surveys of red imported fire ants for phorid fly (Pseudacteon curvatus) were initiated this summer (2012). One demonstration of Reduced Agent Area Treatments (RAAT) for grasshopper control was conducted in eastern Oklahoma in 2012. IPM TRAINING FOR CONSUMER/URBAN ENVIRONMENTS: The IPM demonstration gardens are being installed at the OBGA Gardens, Stillwater. Three videos discussing IPM tools were broadcast through the Oklahoma Gardening, and will be used for future trainings. IPM IN PUBLIC HEALTH: Three bed bug management programs were conducted in 2011. A team was formed to address bed bug issues. IPM TRAINING AND IMPLEMENTATION IN SCHOOLS: OSU (IPM and Pesticide Education) collaborates with the Southwest Technical Resource Center for School and Childcare IPM, along with TAMU and NMSU (http://schoolipm.tamu.edu). We are changing plans and intend to select 1 school to adopt an IPM program over the next 2 years. We will work with and evaluate the program and encourage it to become STAR certified. The IPM Coordinator chairs the IPM Initiative Team, and is a member of 6 other Initiative Teams (Commercial Horticulture, Consumer Horticulture, Wheat Enterprises, Multi-Crops, Stored Wheat, and Turf). He also represents the IPM program at various organizations throughout the state. PROJECT MODIFICATIONS: Two major changes to report: Two collaborators have left OSU.

Impacts
IMPACT: 2011/09 TO 2012/08 AGRONOMIC CROPS: Approximately 848,000 acres of the winter wheat acres were planted to Duster. Gallagher was released in 2012. Both are resistant to Hessian fly. Of the Duster acres planted, 5 percent or 50,000 acres were planted in areas where Hessian fly was a serious problem resulting in an estimated $1.5 million in yield savings. Canola acreage increased to 135,000 acres in 2011. Average yield was approximately 28 bushels per acre, meaning this crop contributed ca. $4.5 million to Oklahoma's agriculture economy. More than 300 producers attended two canola workshops in 2012. Timely reporting of an outbreak of variegated cutworm resulted in prevention of yield loss in ca. 15% of the canola acres for an estimated savings of $170,000. Preliminary results of research conducted on the impact of diamondback moth suggest that timely control could potentially result in ca. $1 million in yield savings. Results of the timely reporting of insect activity in cotton allowed cotton producers to correct pest problems on more than 50,000 acres, resulting in a yield savings of nearly $1.7 million. The cotton crop in Oklahoma was a disaster. Most of the 200,000 plus acres planted succumbed to the drought. Since 2009, five herbicide-resistant weed species have been confirmed in Oklahoma and are spread throughout much of the state. The list of newly confirmed herbicide-resistant weeds includes (with estimates of the number of acres affected) ALS-resistant Italian ryegrass on (estimated) 500,000 to 750,000 acres, documented in 17 counties ALS-resistant cheat on (estimated) 500 acres, documented in three counties Glyphosate-resistant marestail on (estimated) 500,000 to 750,000 acres, documented in nine counties Glyphosate-resistant waterhemp on (estimated) 100,000 acres, documented in six counties Atrazine-resistant Palmer amaranth on (estimated) 50 acres, documented in one county Because there are limited herbicide options to control ALS-resistant grass weeds in wheat, this information provides an important reason to practice crop rotation to more effectively manage weeds in winter wheat.

Outputs
OUTPUTS: In 2010, IPM Oklahoma! was awarded funding to conduct programs in 5 program emphasis areas through Smith Lever 3d E-IPM competitive program. The projects (and funding awarded)include: Coordination ($29,942.00); The IPM Coordinator attended the annual SERA-003 meeting in San Juan Puerto Rico and the Entomological Society of America meetings in San Diego and chaired the Southwest Branch Meeting of the Entomological Society of America. I served on the Southern Region IPM Center Advisory committee and the Oklahoma State University Sustainable Agriculture Advisory Committee. I also provided 18 presentations and wrote 13 articles on topics related to the program emphasis areas listed. IPM Implementation of Agronomic Crops ($113,296.00); Hessian fly pheromone lures were purchased and 3 winter wheat fields monitored for Hessian fly emergence. In addition, the Wheat Improvement Team released "Duster" in 2009, a hard red winter wheat variety that was shown to be resistant to Hessian fly. Area Extension specialists and County Educators provided timely insect activity reports on thrips, stink bugs and cotton fleahoppers during the 2010 cotton growing season through a weekly Talkin' Cotton Newsletter. A weed track sprayer was purchased to allow screening of herbicide resistant weeds throughout the state. Dr. Joe Armstrong is coordinating a statewide screening program. IPM Oklahoma also participated in a multi-state pheromone trapping program for sunflower moth that was coordinated out of North Dakota. IPM Implementation of Animal Systems ($23,505.00); 2 poultry facilities have been identified to use as result demonstrations for biointensive IPM of litter beetles. The demonstrations will begin this April. Plans are underway to evaluate methods for sustainable ear tag management this spring, 2011. Surveys of red imported fire ants for phorid fly are planned for this spring through summer, 2011. IPM Training for Consumer/Urban Environments ($11,000.00); Plans are underway to develop the first of three IPM demonstration gardens that will be located at the Oklahoma Botanical Gardens, Stillwater. Three video episodes discussing biological controls have been broadcast through the Oklahoma Gardening program, and will be used as future training videos. IPM in Public Health ($21,074.00); Bed bug management programs were initiated in 2010. A team of specialists that included a healthy housing specialist, an urban entomologist, a pesticide education specialist and the IPM coordinator was formed. Currently, the team has delivered educational programs for the Oklahoma Chapter of the National Association of Housing and Redevelopment Officials. We are also in contact with the Oklahoma Department of Health for future educational program opportunities. IPM Training and Implementation in Schools ($19,074.00); OSU (IPM and Pesticide Education) remains a partner in the Southwest Technical Resource Center for School and Childcare IPM, along with TAMU and NMSU (http://schoolipm.tamu.edu). Plans are underway to begin working with 1-2 schools to implement and evaluate an IPM program over 3 years. Initial contact with a Native American School is being pursued. PARTICIPANTS: Collaboration with Cooperative Extension was excellent, with participation from OCES county, area and state specialists. The IPM Coordinator chairs the IPM Initiative Team, and is a member of 6 other Initiative Teams (Commercial Horticulture, Consumer Horticulture, Wheat Enterprises, Multi-Crops, Stored Wheat, and Turf). I am also a member of the Wheat Improvement Team which evaluates new wheat varieties that are being developed in Oklahoma. Outside agency involvement included working with National Institute for Food and Agriculture, the Southern Region IPM Center, Great Plains Canola Association, Kerr Center for Sustainable Agriculture, Oklahoma Department of Agriculture, Food and Forestry, Oklahoma Feed and Grain Association, Oklahoma Golf Course Superintendents Association, Oklahoma Grape Growers Association, Oklahoma Invasive Plants Council, Oklahoma Pecan Growers Association, Oklahoma Pest Control Association, Oklahoma School Plant Managers Association, Oklahoma Sorghum Commission, Oklahoma Turf Growers Association, Oklahoma Turf Research Foundation, Oklahoma Wheat Growers Association, Oklahoma Wheat Research Foundation, US Fish and Wildlife Service and the USDA Agricultural Research Service.

TARGET AUDIENCES: Nothing significant to report during this reporting period. PROJECT MODIFICATIONS: One major change has to do with converting partial support of one salary position support of a graduate student, in order to maximize impact from resistant weed screening.
Impacts
Because this is the first year of the program, few documented Outcomes/Impacts have been obtained. However, I wish to highlight a few. Agronomic Crops: The Hessian fly-resistant hard red winter wheat variety 'Duster' which was developed through OSU's Wheat Improvement Team is on target to become the #1 variety planted in Oklahoma in 2011-12. Canola acreage has grown in Oklahoma from 41 acres in 2002 to an estimated 100,000 acres in 2010. Results of research demonstrations and educational efforts provided to canola growers for aphid management showed that producers could save an average of $30 per acre in spray costs with no loss in yield by following newly developed canola aphid management thresholds, resulting in $900,000 in potential cost savings from reduced pesticide applications to the 2009-2010 crop. Results of the timely reporting of insect activity in cotton allowed cotton producers to correct pest problems on more than 50,000 acres, resulting in a yield savings of nearly $1.7 million. Marestail has become a problem because it is an important weed in no-till systems is not effectively controlled with glyphosate. Dr. J.C. Banks (retired) developed a marestail management program . In 2010, growers communicated that fewer acres were lost to uncontrolled marestail (confirmed by visual surveys) and resulted in an increased ratio of harvested to planted acres > 94% in 2010 Through the use of the weed track sprayer 15 marestail (Conyza canadensis) populations were tested for resistance to glyphosate. All of the populations were classified as resistant to glyphosate, when compared to a susceptible population. We have also confirmed ALS-resistance in four populations of cheat (Bromus secalinus) in north central Oklahoma. From some dose response studies that were conducted, these populations have been shown to survive applications of 32 times the labeled rate for commonly used herbicides in wheat. Additionally, since the purchase of the track sprayer, 6 populations of Italian ryegrass (Lolium multiflorum) were screened for resistance to ALS- and ACCase-inhibitor herbicides. ALS-resistance has been previously confirmed as widespread throughout Oklahoma. As a result, most wheat producers have switched to using ACCase-inhibitor herbicides to control Italian ryegrass Since 1991, our musk thistle weevil round-up program collected and redistributed more than 850,000 musk thistle head weevils and 40,910 musk thistle rosette weevils across the state. Landowners in NE Oklahoma have noted from 80% to 95 % decrease in number of musk thistle plants in areas where they are using an integrated approach that includes use of the musk thistle weevils. If the typical landowner applies 1 lb. active ingredient of herbicides per acre annually, biological control has decreased the amount of herbicides applied to the environment by 7.1 million lbs per year.
