Item 2022 Weather and Pest Outlook(2022-05-11) Golpen, Jared; Nicolai, DavidThis episode featured special guest Dennis Todey, Director of the Midwest Climate Hub in Ames, Iowa in addition to Bruce Potter, UMN Extension IPM specialist and Dr. Jeffrey Coulter, UMN Extension Corn Agronomist to discuss the weather and pest outlooks for the 2022 growing season. This session discusses the growing season thus far, which has been slow, with cool and cloudy conditions. As a result, planting progress has been slow despite precipitation being close to normal in much of Minnesota. Southerly winds have also brought some migratory insect pests like Black Cutworm and Armyworm moths up into Minnesota. However, the long range forecast predicts a shift to warmer and drier conditions into the summer months.Item After the flooding - crop disease & weed management considerations(2024-07-03) Golpen, Jared; Nicolai, DavidResources: Flooded corn (https://extension.umn.edu/growing-corn/flooded-corn#:~:text=Corn%20plants%20that%20survived%20flooded,stress%20later%20in%20the%20season); U of MN Herbicide resistant weed survey (https://blog-crop-news.extension.umn.edu/2023/06/multiple-herbicide-resistant-waterhemp.html); Crop Protection Network (https://cropprotectionnetwork.org/); Flooded corn fields and what diseases might you expect to see (https://crops.extension.iastate.edu/blog/alison-robertson/flooded-corn-fields-and-what-diseases-might-you-expect-see); Disease Risk in White Mold and Sudden Death Syndrome of Soybean (https://crops.extension.iastate.edu/cropnews/2024/06/disease-risk-white-mold-and-sudden-death-syndrome-soybean); Have our SCN sorrows been drowned?

Debalin Sarangi, Extension weed management specialist, Tom Peters, Extension sugarbeet agronomist, Seth Naeve, Extension soybean agronomist, and Bruce Potter, Integrated Pest Management Specialist, to discuss cupped soybean leaves. Cupped soybean leaves are no rarity in Minnesota; however, the number of fields with cupped, wrinkled, and or strapped soybean leaves in 2021 is quite extraordinary.Item Bonus – Freezing Temperatures? (5/28/21)(2021-05-28) Golpen, Jared; Nicolai, DavidThis bonus episode featured University of Minnesota Extension Specialists, Dr. Jeff Coulter, Dr. Seth Naeve, Dr. Jochum Wiersma, and North Dakota State University Extension Agronomist Dr. Hans Kandel to discuss the recent freezing temperatures and what that means for crops in northern Minnesota and North Dakota.Item Corn agronomy updates and preparing for soybean insects(2023-07-12) Golpen, Jared; Nicolai, DavidSoybean Gall Midge (https://soybeangallmidge.org/soybean-gall-midge-distribution); Spider-mite (https://extension.umn.edu/soybean-pest-management/managing-spider-mite-soybean); Aphids and mites (https://blog-crop-news.extension.umn.edu/2022/07/management-of-soybean-aphids-and.html); Visual guide for defoliation (https://blog-crop-news.extension.umn.edu/2019/08/defoliating-insects-still-making-their.html); Early season drought effects on corn and soybeans (https://blog-crop-news.extension.umn.edu/2021/06/early-season-drought-effects-on-corn.html)Item Corn and soybean disease: Strategies for effective management in 2022(2022-08-03) Golpen, Jared; Nicolai, DavidDr. Dean Malvick, U of M Extension plant pathology specialist and crops program leader and professor of plant pathology discusses corn and soybean diseases he has observed and what might yet appear in 2022. Since it was first found in Minnesota in 2019, the fungal pathogen that causes tar spot in corn has spread from southeastern Minnesota to as far north and west as Stearns County in three growing seasons. Tar spot-related topics included scouting strategies and identification, when symptoms are likely to be observed, and what research has told us regarding proper active ingredient and application timing for managing tar spot with a foliar fungicide.Item Corn and Soybean Planting Update-Are we on Schedule? or What's next?(2024-05-15) Golpen, Jared; Nicolai, DavidItem Corn and soybean yield updates(2023-08-16) Golpen, Jared; Nicolai, DavidDamage to corn and soybeans in August (https://blog-crop-news.extension.umn.edu/2023/08/hail-damage-to-corn-and-soybeans-in.html); MN Crop News: Northern corn rootworm and extended diapause problems increase in areas of Minnesota (https://blog-crop-news.extension.umn.edu/2023/07/northern-corn-rootworm-and-extended.html); Handy Bt Trait Table for 2023 (https://www.texasinsects.org/uploads/4/9/3/0/49304017/bttraittable_march_2023.pdf); Scouting for Corn Rootworm (https://extension.umn.edu/corn-pest-management/scouting-corn-rootworm)Item Corn nutrient status and herbicide application in hot weather(2022-06-22) Golpen, Jared; Nicolai, DavidIn this episode, Brad Carlson, water resources extension educator, and Dan Kaiser, extension nutrient specialist, discussed nutrient availability in corn, especially nitrogen based on previous crops, use of urea, and other nutrients, such as sulfur. Joe Ikley, Extension Weed Specialist at North Dakota State University also discussed weed and herbicide interactions in the recent hot weather we've been having. Drought-stressed weeds have a tendency to produce more protective cuticle, so additional carrier or surfactant is often needed to get herbicide active ingredient penetration into the plant. Anthony Hanson gave updates on insect issues occurring in mid-June, such as true armyworm and alfalfa weevil.Item Corn pollination, atrazine herbicide use, and July insect updates(2022-07-18) Golpen, Jared; Nicolai, DavidDr. Jeff Coulter, U of M Extension Agronomist, updated us on the current status and outlook of corn pollination. Significant progress across much of the state should be occurring in the next week, though because of variable planting dates, it is difficult to generalize how upcoming hot weather will affect the overall crop across the state. Currently projected highs in the lower 90s should not cause significant pollination issues.Seth Dibblee, Environmental Scientist with the EPA, was on to discuss current news with atrazine. Atazine is a widely used post-emergence herbicide with about 33% of planted acres having an application in 2021. Currently, there are water quality concerns with atrazine that the EPA is proposing to address by adding restrictions to reduce runoff, such as disallowing use on saturated soil. A public comment period is open until Sept. 6, 2022 at: https://www.regulations.gov/search?filter=EPA-HQ-OPP-2013-0266. Dr. Anthony Hanson also gave a quick update on insects in early July. So far, soybean aphid hasn't reached economic thresholds across much of the state, but populations are starting to increase in some areas. Whether it's soybean aphid or other insects, be sure to check the insecticides are actually approved. Chlorpyrifos application , even if it's in possession from a previous year, is no longer allowed for any agricultural use.Item Corn Rootworm Current Status, etc. and crop disease update/fungicides(2022-06-29) Golpen, Jared; Nicolai, DavidThe months of July and August typically brings new challenges for corn and soybean growers in Minnesota. In this week's episode, Bruce Potter, Extension Integrated Pest Management Specialist and Andy Nesseth, part owner, Agronomist/Consultant from Extended Ag Services of Lakefield, MN provided an update and reviewed management strategies for corn rootworm in Minnesota. Because of the delayed spring planting season and resistant corn rootworm populations, Minnesota corn growers face numerous field by field management situations for adequate corn rootworm control. Bruce and Andy discussed the use of field traps and scouting as part of these management strategies along with recommended crop and Bt hybrid rotations. The last portion of the program included Dr. Dean Malvick, University of Minnesota Extension Plant Pathologist for corn and soybeans. Dean provided an update of the biology and cultural control of corn tar spot, SDS (sudden death syndrome) in soybeans, white mold, and frog eye leafspot in soybeans. Dean also reviewed the possible use of fungicides for some of these diseases in terms of proper application timing.Item Corn updates and crop disease considerations(2024-07-17) Golpen, Jared; Nicolai, DavidResources: Corn IPM Pipe (https://corn.ipmpipe.org/tarspot/); Crop Protection Network (https://cropprotectionnetwork.org/); Minnesota Ag News – Crop Progress & Condition (https://drive.google.com/file/d/1FnZ6XfP4qE6Wjg4WoTRCORx3HRcUowb6/view?usp=drive_link); Plant Disease Clinic (https://pdc.umn.edu/); Flooded corn fields and what diseases might you expect to see (https://crops.extension.iastate.edu/blog/alison-robertson/flooded-corn-fields-and-what-diseases-might-you-expect-see); Disease Risk in White Mold and Sudden Death Syndrome of Soybean (https://crops.extension.iastate.edu/cropnews/2024/06/disease-risk-white-mold-and-sudden-death-syndrome-soybean); Flooded corn (https://extension.umn.edu/growing-corn/flooded-corn#:~:text=Corn%20plants%20that%20survived%20flooded,stress%20later%20in%20the%20season)Item Crop management considerations during this abnormally dry season(2023-06-28) Golpen, Jared; Nicolai, DavidEarly season drought effects on corn and soybeans (https://blog-crop-news.extension.umn.edu/2021/06/early-season-drought-effects-on-corn.html); Rochester Tour (https://blog-crop-news.extension.umn.edu/2023/06/save-date-for-rochester-crop-management.html)Item Crop management considerations for soggy fields(2024-06-26) Golpen, Jared; Nicolai, DavidReferenced during presentation (https://drive.google.com/file/d/1SGHvVC31Xjk7tfqETpwt9h_1Wo11NFAF/view?usp=drive_link).

Jochum Wiersma (small grains), Jeffrey Coulter (corn) , and Seth Naeve (soybean). Many areas of the state are still dealing with wet conditions, especially northwestern and west-central regions. While delays are decreasing potential yield, current crop prices may help buffer some of the effects of those delays. Growers should discuss with their insurance agent what options they may have for prevented plant acres. Areas with heavy flooding or erosion immediately after planting are a concern in central MN, especially for corn, so now is a time to assess plant stand and health.
