Dave Nicolai and Dr. Seth Naeve talk about agronomic issues from the recent heavy rains in early May 2023 and early-season insect issues with Bruce Potter, IPM Extension Specialist based out of Lamberton, MN. Potter has been monitoring black cutworm and true armyworm flights as well as alfalfa weevil that may be affecting crops in upcoming weeks. Diseases to watch out for in flooded or wet soils include soybean sudden death syndrome, Pythium, and Fusarium.

Dave Nicholai gives an update on planting progress with Dr. Seth Naeve and discusses weed management tactics early in the season with Dr. Debalin Sarangi. Weeds such as waterhemp are already emerging with the warming temperatures. They focused on herbicide options for weed management, especially how to time pre-emerge and post-emergence options along with possible tank-mix strategies.

Dave Nicolai discusses May planting and potential early-season diseases with U of M Extension plant pathologist Dean Malvick and soybean agronomist Seth Naeve.

It's late April in 2023 and it's still wet and difficult to get field work done across the state. It's a bit too early to discuss much about pests, but as a lead-in to future early-season pest issues that could result from this late spring, it's important to look at agronomic issues related to planting when soils are still cold and wet. Dave Nicolai chats with U of M agronomists Drs. Jeff Coulter and Seth Naeve about current field conditions and when to plant corn and soybeans.  

Dr. Bob Wright with the University of Nebraska discusses with Dr. Anthony Hanson how integrated got its start and Dr. Hanson goes through how we have adapted IPM plans to new invasive pests, such as soybean aphid. The two segments were produced as part of a 50th anniversary of IPM podcast supported by the USDA, National Institute of Food and Agriculture and the North Central IPM Center hosted at: https://feeds.buzzsprout.com/2039018 The IPM Podcast will be going on break in 2023 to focus on producing IPM updates for UMN Extension's Strategic Farming programs. You can contact Anthony Hanson at [email protected] with IPM questions in Minnesota.

Dr. Trisha Leaf from the Minnesota Department of Agriculture discusses how recent pesticide regulatory changes for pesticides such as chlorpyrifos, Enlist Duo (glyphosate & 2,4-D) and dicamba will affect farmers this year.

After 38 years with the University of Minnesota, corn entomologist Dr. Ken Ostlie is retiring at the end of January. He stopped by to talk about corn insects and entomology over the years and where he sees the field going in the future.

Dr. Aaron Lorenz, soybean breeder and Associate Professor at the Department of Agronomy and Plant Genetics at the U of M discusses how soybean breeding is actually done and what work is going on at the U to improve soybeans.

Dr. Janet Knodel, Extension Entomologist at North Dakota State University, discusses what to keep an eye out for when thinking about pests in or around stored grain. Sanitation and prevention are often the easiest and most cost effective tools due to the difficulty of treating pest issues once they are found.

Liz Stahl, U of M Regional Extension Educator based out of Worthington, discusses what she has learned from the annual IPM Assessment, a survey of growers across the state about their pest management use and concerns. Perceptions on what neighbors are doing can influence grower decisions, though one farmer after seeing this survey data remarked, "Wow, I thought all my neighbors were using fungicide on their corn." Often times, growers are using less pesticide than we might perceive.

Episode 21. Drs. Jochum Wiersma and Jared Goplen give updates on pest management in small grains in 2021. Recorded May 20, 2021.

Dr. Greg Tykla, nematologist with Iowa State University and Dr. Samuel Markell, Extension broadleaf plant pathologist at North Dakota State University discuss soybean cyst nematode and the challenges with managing this pathogen.
