Target Audience: Agricultural professionals (consultants, elevator/cooperative personnel, agrochemical/industry personnel, independent applicators, etc), commodity groups soybean, corn, small grains, and sugarbeet), growers, agricultural financial personnel, government personnel (NRCS, school districts, etc) Changes/Problems: One IPM Specialists retired in 2011 (Dr. Carlyle Holen). We have modified the program to include a number of Regional Extnsion Educators, already involved in MN IPM activities. This has provided the program with wider geographic representation, strengthened some areas of expertise and provided more flexibility to the program as a whole. These changes were implemented in the 2012 grant year. In additin, a new position will be created in the upcoming year. We will have 1 FTE dedciated to developing, disseminating and coordinating digitally based IPM information developed by participants and cooperators. What opportunities for training and professional development has the project provided? In 2009, IPM Adoption Surveys of independent growers indicated they rely on professional crop advisors and University resources for pest management information. In 2011, the UMN Extension IPM Program continued to focus on delivering education to Agricultural Professionals to act as message multipliers, incorporating newsletters and other electronic and digital outreach publications directed to both professional and grower audiences to educate growers. These efforts were supplemented with face to face meetings and field demonstration projects. In 2012, over 30 extension event meetings targeted to agricultural professionals, over 80 event meetings targeting growers, over 40 research and demonstration plot locations were conducted. Educational programs were the result of the collaborative efforts of 8 state faculty specialists, 27 UMN Extension personnel, 8 multistate collaborative research/extension efforts, and collaborations with industry personnel. In 2012, personnel from the IPM Program participated in programming and delivering content in multi-day Field Schools for Ag Professionals at 1 location; The Annual Crop Pest Management Short Course (1320 attendees), The Annual Agricultural Professional Update at 6 locations across the state (>350 individuals); Commercial, Noncommercial and Structural Pesticide Recertification Workshops at >25 locations across Minnesota; Winter Crops Days at multiple locations, and ~35 other events targeted at Agricultural Professionals throughout Minnesota. How have the results been disseminated to communities of interest? The IPM program supported 3 regional newsletters and 3 websites providing current IPM information and management recommendations: Cropping Issues in NW MN reports on developing IPM issues in northwest MN, SW MN IPM does the same for the SW, and Crop Connection the SE MN Regional Ag Newsletter. In 2012, the results from all cropping regional research and demonstration trials conducted by UMN Extension personnel in southern Minnesota were made available in a single report ("2012 Southern Minnesota Regional Research & Demonstration Trials"). UMN-IPM personnel helped develop and produce this report which includes methods, results, and full-color photos of most plots. To ensure an extension program effectively reaches its audience, some form of program evaluation is necessary. At annual pesticide applicator recertification meetings, we conduct an IPM Adoption Survey assessing the success of our educational efforts. Results are also presetned at events targeted at agricultural professionals (as above) and producers. IPM Personnel were involved in programming and delivering content at over 70 grower targeted events throughout the year in Minnesota and collaborating neighboring states, including Prairies Grains and Best of the Best events covering small grains and soybeans; Barriers to Bushels covering soybeans and corn; Sugarbeet Research & Education Board Annual Research Reporting Sessions, sugarbeet growers seminars and the International Sugarbeet Institute; Twilight Tour and Plot Days for potato and seed potato industries; and numerous grower events, plot and field tours, and Industry meetings throughout the growing season across Minnesota and neighboring collaborating states. What do you plan to do during the next reporting period to accomplish the goals? The Agricultural Professional Updates, the Crop Pest management Short Course and Pesticide Applicator Training sessions will be held through the winter extension season, as will numerous other UMN Extension events. The websites, blogs, newsletters and other publications will be continued. In addition, we will be establishing a new position with the responsibilities of coordinating IPM information disseminated in digital formats (web, video, social media, Vine and other digital formats). The participants will continue to meet the goals of this project.

What was accomplished under these goals?
University of Minnesota Extension and the UMN IPM Program annually designs and implements a series of IPM Adoption surveys. These surveys are conducted at Pesticide Applicator training and re-certification programs, ensuring a wide audience and high level of response. UMN Extension IPM personnel are pivotal in the originating this survey and continued to be heavily involved in their development and implementation. The survey is redesigned annually to assess not only the success of individual efforts and contributions, but when the results from all locations are analyzed; they provide a method whereby regional programming success can be evaluated. In 2012, 830 producers participated, answering questions designed to assess pest management in Minnesota (although not all 830 answered questions on the same cropping systems as the state wide survey crosses production areas). Events: In order to meet the needs of our clientele, UMN EFANS IPM Program participates in Extension events targeted both at producers and at agricultural professionals (through the UMN Institute for Agricultural Professionals). Some of the most successful and best established of which included the annual Agricultural Professional Updates, the Crop Pest Management Short Course, Winter Crop Days, the Commercial and Private Pesticide Applicator Training Programs, and multiple Field Days and plot tours. The UMN IPM Program personnel also collaborate with county and regional Extension Educators in the development and delivery of local and regional Extension programming related to pest management. Through the growing season of 2012, many Minnesota producers and agricultural professionals were battling resistance issues in corn, soybeans and potatoes. Increasing tolerance to insecticides, herbicides and fungicides were being encountered in all three cropping systems. Consequently, throughout the season and well into the fall and early winter, Extension programming was designed and delivered to provide insight into the development and management of pesticide resistance. This represented individual efforts by UMN IPM personnel across the state to ensure that Minnesota producers and agricultural professionals understand why the existing problems are developing and what can be done to manage the situation. Grower Participatory Research/Demonstration: There is a long history of grower participation in Minnesota’s Extension delivery. In 2012, the UMN IPM Program was assisted by growers in establishing on-farm research and demonstration trials at over 30 locations. These included soybean, small grain, corn, and alfalfa plots used to assess and demonstrate a wide variety of pest management tactics varying from insect management to insecticide resistance. The increasing problem of glyphosate resistance in Minnesota has resulted in significant research and demonstration on recognizing and managing resistant weeds. Evaluation: Of particular interest were the responses dealing with the onset of resistance in corn (to Bt traits) and to glyphosate, both of which indicated a growing awareness and concern over both issues. These data underscore the growing concern of growers about pesticide resistance. In Minnesota, these concerns were accelerated when laboratory trials confirmed chlorpyrifos resistance in some Two Spotted Spider Mite populations in soybeans. Consequently, the UMN EFANS IPM Program incorporated resistance management information in plot tours and fields days in the summer of 2013. This will also be a focus for events in 2013/14. In addition, a new extension project, initiated in 2012, was continued through the growing season of 2013. IN an effort to provide information to seed potato growers in MN (and North Dakota) on the incidence of aphid vectors of virus diseases, a suction trap network was established. While this network generates research data, it also provides seed potato producers with vital information needed for the timing of aphid management tactics. Weekly information on the densities and distributions of these insects was made available via direct email (with assistance of the Northern Plains Potato Growers Assoc), Twitter (#MNSpudbug), and a blog (aphidalert.blogspot.com).

The survey is redesigned annually to assess not only the success of individual efforts and contributions, but when the results from all locations are analyzed; they provide a method whereby regional programming success can be evaluated. In 2011, this survey indicated that as a result of University of Minnesota Extension IPM training more than half of respondents have significantly increased their use of monitoring and field scouting, more than 60% have significantly increased their use of safety precautions when using pesticides and keeping field records. Results also indicate that producers in southern MN are increasingly relying on UMN Extension IPM sources for initial information; producers in northern MN rely more on Coops and consultants for initial information but value UMN Extension for research results. Much of the 2011 survey focused on the prevalence and management of glyphosate resistant weeds. Approximately 69% of respondents indicated that glyphosate was not currently working as well as in the past. The top two tactics employed for managing resistant weeds tank mixing additional herbicides and rotating modes of action. Surveys indicated a growing adoption of mobile devices but an overwhelming number again this year stated they preferred hard-copies of extension bulletins, newsletters and fact sheets. We are increasing the inclusion and dissemination of these products at extension events. Other advanced application technologies, such as GPS mapping, auto boom and auto steering also seem to be increasingly adopted. These results demonstrate the inroads made by the UMN Extension IPM Program. For example, an overwhelming proportion of respondents report utilizing foliar applications in soybeans as a response to thresholds (~66.67%) and past surveys indicate as many as 80% of producers using thresholds are utilizing the threshold of 250 aphids/plant as recommended by UMN Extension. In the face of marketing pressure, this underscores the success of the UMN IPM programming efforts. Similar results can be found in glyphosate resistance, soybean cyst nematode and corn rootworm programming activities.

OUTPUTS: In 2009 and 2010 IPM Adoption Surveys of independent growers, most reported relying on both Elevator/Cooperative resources and University resources, newsletters and websites for the majority of their pest management information. Consequently, in 2010, the UMN IPM Program continued to focus on delivering education to Agricultural Professionals to act as message multipliers and incorporate newsletters and other electronic and digital outreach publications directed to both professional and grower audiences educate growers. These efforts were heavily supplemented with meetings and demonstration projects. . In 2010, we also began to develop a pilot program to provide quick updates on developing pest problems to crop consultants. This program, called Heads-Up Network will provide text messages to crop consultants by region and crop system interests. In 2010, personnel from the IPM Program participated in programming and delivering content in multi-day Field Schools for Ag Professionals at 2 locations; The Annual Crop Pest Management Short Course held in conjunction with The Minnesota Crop Production Retailers Association (~1500 attendees), The Annual Agricultural Professional Update at 6 locations across the state; Commercial, Noncommercial and Structural Pesticide Recertification Workshops at 29 locations across Minnesota; Winter Crops Days at multiple locations, and ~35 other events targeted at Agricultural Professionals throughout Minnesota. In addition, IPM Personnel were involved in programming and delivering content at over 100 grower targeted events throughout the year in Minnesota and in collaborating neighboring states, including Prairies Grains and Best of the Best events covering small grains and soybeans; Barriers to Bushels covering soybeans and corn; Sugarbeet Research & Education Board Annual Research Reporting Sessions, Sugarbeet Growers Seminar and the International Sugarbeet Institute; Twilight Tour and Plot Days covering potato and seed potato industries; and numerous grower events, plot and field tours, and Industry meetings throughout the growing season across Minnesota and neighboring collaborating states. The IPM program also supported 3 regional newsletters and 2 websites providing current IPM information and management recommendations: Cropping Issues in NW MN and the website Red River IPM reports on developing IPM issues in northwest MN, SW MN IPM does the same for the SW, and Crop Connection the SE MN Regional Ag Newsletter. In 2010, the results from all cropping regional research and demonstration trials conducted by UMN Extension personnel in southern Minnesota were made available in a single report ("2010 Southern Minnesota Regional Research & Demonstration Trials").

Results also indicate that producers are increasingly relying on UMN Extension IPM sources for research and field trial results and unbiased IPM information. Almost 60% report relying on UMN sources for accurate data and other UMN IPM extension materials to gain IPM related knowledge and practices. Surprisingly, only approximately half of respondents extensively use the internet to obtain IPM information while an overwhelming 85% use UMN Extension newsletters as primary, valued sources for IPM information. In 2010 the survey indicated that a greater distribution network of these publications would be helpful. We are currently investigating partnerships with elevator and co-op organizations to distribute publications of interest. These results demonstrate the inroads made by the UMN Extension IPM Program. For example, one of our greatest successes has been the increasing adoption and utilization of the recommended soybean aphid threshold of 250 aphids/plant when 80% of plants are infested. In the face of marketing pressure, this underscores the success of the UMN IPM programming efforts. Similar results can be found in glyphosate resistance, soybean cyst nematode and corn rootworm programming activities.
