What opportunities for training and professional development has the project provided?In 2014, the project held one twilight meeting (25 attendees) for wine grape growers to discuss red blotch virus which at the time was an emerging virus of grape vines suspected to be vectored by insects (suspected to be leafhoppers). The project also organized and conducted a full day course on Grape IPM in March that was attended by 45 grape growers. In 2015, the project held three blueberry twilight meetings (50 attendees) to discuss insect and disease management, two grape twilight meetings (34 attendees) to discuss red blotch virus which is an emerging virus of grape vines that may be vectored by insects (suspected to be leafhoppers), and organized and conducted a second full day course on Grape IPM in March that was attended by 35 grape growers. During 2016, three blueberry twilight meetings were held (36 attendees) to discuss insect and disease management. The project held two grape twilight meetings (one in Northern NJ, one in Southern NJ, 31 attendees total) to discuss insect and disease management including red blotch virus and its suspected insect vectors. During the final year of the project (2017), three annual meeting and 3 twilight meeting were held for blueberry growers to discuss management issues and solutions. In addition, results from the honey bee health objective added in 2016 was presented at three grower meeting involving blueberry and cranberry growers. How have the results been disseminated to communities of interest?During course of this grant the information generated by the project was distributed via weekly newsletters ~30 per year, 23 grower meetings attended by 926 growers (blueberries - 86; grape -90, honey bees - 240), two grape IPM courses attend by 45 growers in 2014 and 35 growers in 2015, and the use of the Rutgers Plant & Pest Advisory blog. What do you plan to do during the next reporting period to accomplish the goals?

What was accomplished under these goals?
During the project the following items were accomplished: 2014 IPM Outreach and Delivery Coordination 1. Conducted 2 quarterly meetings with the coordinators of NJ's 4 IPM programs. 2. Held 1 advisory committee meeting. 3. Attended NJ IPM Task Force and School IPM Advisory Committee meetings. 4. Participated in the NE IPM technical committee (NEERA 104); served as the chair in 2015. Blueberry IPM Program Delivery 1. Provided IPM programming to growers that manage 70% of NJ's blueberry acreage. 2. Provided weekly information via newsletters/blogs to >95% of all growers. 3. Added 3 new growers to the program. 4. Assisted in the updating and distribution of a blueberry production guide. Wine Grape IPM demonstration and development 1. Collected leaf samples from 6 vineyards that were tested for viruses. Four were positive for red blotch, 2 were positive for leaf roll viruses. 2. Presented a poster at the Eastern Branch ESA meeting on brown marmorated stink bug and spotted winged drosophila impacts on wine grapes. 3. Initiated a survey in 9 vineyards for insects and viruses. 4. Conducted an efficacy trial using organic insecticides against grape berry moth. 5. Published a wine grape production recommendation guide. 2015 IPM Outreach and Delivery Coordination 1. Conducted 2 quarterly meetings with the coordinators of our 4 IPM programs. 2. Held one advisory committee meeting. 3. Attended NJ IPM Task Force and NJ School IPM Advisory Committee meetings. 4. Participated as a member NE IPM technical committee (NEERA 104). Blueberry IPM Program Delivery 1. Educated rowers about novel management methods for blueberry pests. 2. Public IPM awareness was improved via demonstrations, articles, county reports and other outreach. Articles appeared in 2 newsletters with 44 editions (printed and web versions), with over 2250 subscribers (including mail and webblog subscriptions). Newsletters on the Web recorded over 7,000 views or downloads. 3. The average grower using IPM practices saved about $100/A. 4. New pest management practices such as mating disruption and whole farm GIS based monitoring were used. 5. IPM training of students/farm employees created new IPM interns, professionals and researchers. 6. Soil and plant fertility monitoring during 2015 fertility tests demonstrated that about 75% of fields sampled had sufficient to high levels of soil phosphorous. 7. Adjustments in 2015 to help protect the blueberry industry from spotted wing drosophila while minimizing conventional OP and carbamate insecticide use. Due to this, while non-managed fields showed over 100 maggots per qt, no rejections were reported by IPM participants. Wine Grape IPM demonstration and IPM development 1. A Grape IPM School was conducted for 35 growers and extension educators. Experts from outside of NJ provided basic information on key pest id and management. A clicker-survey was conducted during the meeting to identify current management tactics and areas of concern for wine growers. 2. Grape berry moth occurred at all locations surveyed and showed that the recommended degree-day timings for proper management were inaccurate. 3. The red blotch virus survey showed that it has become more important since it's finding in 2014. Its presence caused some growers to remove grape vines. Since little information is currently known about red blotch transmission of red blotch virus we coordinated leaf tissue analysis for red blotch virus. We will pair geo-referenced symptomatic vines with molecular data and visual observations of symptoms which will allow us to develop diagnostic tools that can be used by growers throughout the state. 4. This project helped to establish a connection between Rutgers University, Rutgers Fruit IPM Program and regional wine grape growers. 2016 IPM Outreach and Delivery Coordination 1. Conducted 2 quarterly meetings with the coordinators of our 4 IPM programs. 2. Held one advisory committee meeting. 3. Attended NJ IPM Task Force and NJ School IPM Advisory Committee meetings. 4. Participated as a member NE IPM technical committee (NEERA 104). Blueberry IPM Program Delivery 1. Growers were educated about novel management methods for a variety of pests in blueberries. 2. T Public IPM awareness was improved via demonstrations, articles, county reports and other outreach. Articles appeared blueberry newsletters published weekly through the growing season (printed and web versions), with over 2000 subscribers (including mail and web blog subscriptions). The web-based newsletters recorded over 6,500 views or downloads. 3. Growers minimized on farm pest management costs (up to 50% lower amounts of pesticides/acre). 4. Mating disruption and whole farm GIS based monitoring continued to be used. Mating disruption was used primarily for control of Oriental beetle. 5. IPM training of college students/farm employees resulted in six students and seasonal workers, and one farm employee being trained as IPM scouts, enabling 66% of NJ blueberry acreage to be under IPM practices. Wine Grape IPM demonstration and IPM development 1. Grape berry moth occurred at all locations surveyed. 2. The survey component for red blotch has become of greater importance since its finding in NJ in 2014. Its presence is associated with a significant reduction in grape quality, and had caused some growers to remove grape vines. A costly process that is not an assured management tactic as little information is currently known about transmission of red blotch virus. The collaboration with Dr. Bradley Hillman at Rutgers University in 2016 to conduct leaf tissue analysis allowed pairing of georeferenced symptomatic vines with molecular data and visual symptom observations of symptoms as a diagnostic tools that growers can be used. 2016-2017 Honey Bee Health 1. Each year, non-migratory honeybee hives weremaintained at cranberry and blueberry farms alongside commercial hives. 2. Each year during bloom, pest management recommendations that took into account the negative impact pesticides may place on honeybees were made to growers and measured brood growth, parasitism, disease occurrence, and queen replacement. Pesticide residues were collected from the hives used during pollination. 3. Each year the samples taken were been sent to the New Jersey Department of Environmental Protection laboratory for analysis. 4. Over 30 pesticide residues were found to be present in honey bee hives used for pollinating NJ blueberries and cranberries in 2016 and 2017. These included insecticides, fungicides, herbicides and miticides used for varroa mite control. Virtually all fungicides used during blueberry bloom were present in hives. 5. At the same time beekeepers continued to suffer significant losses in dead workers, queenless hives, and overall decline found shortly after blueberry pollination. 6. These results were presented at 3 grower/beekeeper meetings (240 in attendance) and resulted in a set of provisional recommendations, including the avoidance of aerial spraying during bloom, avoidance of direct overspraying of hives during pollination, use of evening only fungicide applications, and removal of hives during fungicide applications. 7. This funding led to one NESARE grant (approx. $200,000), one State Specialty Crop Block Grant ($40,000), and funding from the NJ Blueberry Industry Council ($9,700). 2016 Zika Awareness This objective was added in September of 2016 with the intent to develop science based information for New Jersey resident and others out side the state that could be delivered using the internet as the distribution vehicle. The informational materials and websites developed is available at http://vectorbio.rutgers.edu/zikalinks.php. This main page provides links to materials developed by the Rutgers Center for Vector Biology, the Centers for Disease Control, the World Health Organization, and a review of current Zika Virus knowledge written by Musso and Gubler in 2016.

What was accomplished under these goals?
Objective 1 - Increase awareness of and adoption of IPM programs During 2017 the following activities were conducted: 1) Conducted two quarterly meetings with the New Jersey coordinators of the fruit, greenhouse, nursery, and vegetable IPM programs, 2) Held oneadvisory committee meeting inMarch 2017, 3) Attended meetings of the New Jersey Departmetn of Environmental Protection'sIPM Task Force and School IPM Advisory Committee, and 4) Participated as a member of the NortheastIPM Technical Committee (NEERA104). Objective 2 - Continue to off an IPM program in blueberries During 2017, the following activities were conducted: 1) Growers were educated about novel management methods for a variety of pests in blueberries, 2) Through demonstrations, articles, county reports and other outreach, public awareness on IPM was improved. Articles appeared blueberry newsletterspublished weekly through the grwoing season(printed and web versions), with over 2000 subscribers (including mail and web blog subscriptions). Newsletters on the Web recorded over 6,500 views or downloads. 3) Growers minimized on farm pest management costs. Some growers continue to apply large amounts of pesticides/acre while the average IPM participant up to 50%lower amounts of pesticides/acre, 4) Mating disruption and whole farm GIS based monitoring continue to be used on farms participating in the program withmating disruption beused primarlity for control of Oriental beetle, and 4) IPM training of college students and farm employees created new IPM interns, professionals and researchers.The program trained six students and seasonal workers, and one farm employee as IPM scouts, enabling 66% of NJ blueberry acreage to be under IPM practices, and an additional 16% of NJ acreage to be self scouted. Objective3 - Offer an IPM program in grapes Grape berry moth occurred at all locations surveyed. A critical finding was that the recommended degree-day timings for proper management were inaccurate.This data is still being analyzed. The survey component forred blotch has become of greater importance since its finding in NJ in 2014. Its presenceis associated with a significant reduction in grape quality, andhad caused some growers to remove grape vines.

We will be able to pair georeferenced symptomatic vines with molecular data and visual observations of symptoms which willallow us to develop diagnostic tools that can be used by growers throughout the state. This project has also helped to establish a connection between RutgersUniversity, Rutgers Fruit IPM Program and regional wine grape growers. As there is currently no IPM program for wine grapes, this is an important output of this research. Understanding where and how growers receive and utilize management recommendations is critical to developing delivery programs. Objective 4 - Honeybees This objective was added in September of 2016 with the intent to develop baseline data targeting grower use of pesticides duringblueberry and cranberry bloom.In the spring of 2017, non-migratory honeybee hives were established and maintained by project staff at cranberry and blueberry farms alongside commercial hives. During bloom, pest management recommendations that took into account the negative impact pesticides may place on honeybees were made to growers and measured brood growth, parasitism, disease occurrence, and queen replacement. We also collected pesticide residues from the hives used during pollination. The biological data collected data are currently being analyzed. The samples taken from hives has been sent to the New Jersey Department of Environmental Protection laboratory for analysis.During 2017, non-migratory honeybee hives were established and maintained by project staff at cranberry and blueberry farms alongside commercial hives.

What do you plan to do during the next reporting period to accomplish the goals?Coordination of New Jersey IPM Outreach and Delivery Program (Hamilton) The overall objectives of this portion of the proposal are to continue to provide statewide coordination of current programs, coordinate advisory meetings with stakeholders, respond to IPM-related inquires, coordinate and report on state/institutional activities, develop new initiatives via the use of a statewide advisory committee and represent NJ Agricultural Experiment Station on state and regional IPM committees. During year 3 of this project the state IPM coordinator will Conduct an annual advisory meeting to review the goals, objectives and activities of the IPM program and to set yearly priorities to be addressed by the state IPM coordinator, Participate at the state level as a member of the NJ IPM Task Force and NJ School IPM Advisory Committee, Advise commodity and industry groups on IPM issues, Participate at the regional level as a current member NEREAP-IPM committee, When requested the IPM coordinator will survey state specialist in affected areas and report to the person and/or agency making the inquiry. Records of all activities to generate the requested information will be maintained, Coordinate and report on state/institutional activities to USDA. Continued Delivery of a Blueberry IPM Program (Polk) The overall objective of this portion of the proposal is to deliver current IPM information and provide on farm IPM programs to NJ blueberry growers. During year 3 of this project we will Train IPM scouts and growers on the proper identification of blueberry pests, Offer scouting program to NJ blueberry growers, Provide pest management recommendations to blueberry growers, Deliver IPM presentations to blueberry growers at one annual winter meeting, Deliver current pest information to blueberry growers during the spring and summer twilight meetings. Wine Grape IPM demonstration and IPM development (Nielsen, Polk, Hamilton) The overall objective of this portion of the proposal is to deliver current IPM information to NJ wine grape growers. However, because there is no current established NJ wine grape IPM program there is a need for the development of an on farm IPM program. During year 2 of this project we will Complete the survey begun in Year 1 to identify identity and seasonality of pests of interest, Analyze leaf tissue samples during Year 1 for red blotch virus, Analyze preliminary data on DD models for grape berry moth, Present Year 2 findings to growers at Grape Expectations (n=~100) in February, Submit manuscripts on the seasonality of BMSB in wine grapes, injury diagnosis and phenology, Refine and repeat Year 1 survey with more focused timings based on 2015 findings, Update production guide as needed.

What was accomplished under these goals?
Coordination of New Jersey IPM Outreach and Delivery Program (Hamilton) Conducted 2 quarterly meetings with the coordinators of our fruit, greenhouse, nursery and vegetable IPM programs, Held an advisory committee meeting in February 2105, Attended meetings of the NJ IPM Task Force and the NJ School IPM Advisory Committee, Participated as a member NE IPM technical committee (NEERA 104). Continued Delivery of a Blueberry IPM Program (Polk) Growers were educated about novel management methods for a variety of pests in blueberries. Through demonstrations, articles, county reports and other outreach, public awareness on IPM was improved. Articles appeared in 2 newsletters with 44 editions (printed and web versions), with over 2250 subscribers (including mail and web blog subscriptions). Newsletters on the Web recorded over 7,000 views or downloads. Growers minimized on farm pest management costs. Some growers spent as much as $250/A for pesticides while the average IPM participant spent $140/A. The average grower using IPM practices saved about $100/A. New pest management practices such as mating disruption and whole farm GIS based monitoring were used. Small plot research/demonstration trials for Oriental beetle mating disruption continued to show that Oriental beetle could be managed with mating disruption in place of soil applied insecticide. Based on our research and demonstration work, a registration package is now finished, and commercial use started in 2013. IPM training of students and farm employees created new IPM interns, professionals and researchers. The program trained 6 students and seasonal workers, and 1 farm employee as IPM scouts, enabling the 66% of NJ blueberry acreage to be under IPM practices, and an additional 16% of NJ acreage to be self scouted. Fertility monitoring leads to recommendations of lower fertilizer use. During 2015, 348 samples were taken for combined monitoring of plant fertility and nematode levels. Soil and plant fertility tests demonstrated that about 75% of fields sampled had sufficient to high levels of soil phosphorous. In 2012, the spotted wing drosophila developed as a serious invasive pest in blueberries nationwide. While this is a serious threat to IPM programming, we made adjustments in 2015 to help protect the blueberry industry while minimizing conventional OP and carbamate insecticide use. While non-managed fields showed over 100 maggots per qt of berries, no fruit rejections were reported by IPM participants. While insecticide applications averaged just over 11 applications per field, OP and carbamate use was minimized to under 50% of total applications. Wine Grape IPM demonstration and IPM development (Nielsen, Polk, Hamilton) A Grape IPM School, was conducted that was attended by 35 growers and extension educators. Experts from outside of NJ were brought in to provide basic information on pest identification and management of key issues facing NJ growers. A clicker-survey was conducted during the meeting to identify current management tactics and areas of concern for wine growers. Survey results indicate that grape root borer was found at 42.8% of the sites sampled. This represents a more Northern distribution of this pest species than originally thought, although only at one site did populations reach an economic threshold where the grower would have to treat. Grape berry moth occurred at all locations surveyed. A critical finding was that the recommended degree-day timings for proper management were inaccurate. This data is still being analyzed. The survey component for red blotch has become of greater importance since its finding in NJ in 2014. Its presence, and it associated significant reduction in grape quality, had caused some growers to remove grape vines. A costly process that is not an assured management tactic as little information is currently known about transmission of red blotch virus. We have coordinated with Dr. Bradley Hillman at Rutgers University who is conducting the leaf tissue analysis for redblotch virus. We will be able to pair geo-referenced symptomatic vines with molecular data and visual observations of symptoms which will allow us to develop diagnostic tools that can be used by growers throughout the state. This project has also helped to establish a connection between Rutgers University, Rutgers Fruit IPM Program and regional wine grape growers. As there is currently no IPM program for wine grapes, this is an important output of this research. Understanding where and how growers receive and utilize management recommendations is critical to developing delivery programs.
