    Katelyn Kesheimer, assistant professor and extension specialist, Auburn University, Auburn, AL

    This presentation will focus on fall armyworms and corn earworms, pests that are known to wreak havoc across many crops. We will discuss what the heck happened in 2021 that saw one of the largest infestations in recent history, and how we can better prepare with a solid integrated pest management plan in the future.

    Ashley Dean, extension specialist, Entomology, Iowa State University, Ames, IA; Erin Hodgson, professor and extension entomologist, Iowa State University, Ames, IA

    Setting up traps is an easy and passive way to get information about insect pests. Information from statewide and regional insect trapping networks helps farmers make informed management decisions for pests and ensures profitable crop production. Learn how we use these networks to aid in scouting and management and how you can get involved!

    Nathan Kleczewski, plant disease and entomology specialist, Growmark, Champaign, IL

    2021 was a field season filled with disease and insect issues. This talk will discuss the most prevalent issues observed throughout the Midwest, their management, and identification. Topics including corn rootworm, fall armyworm, soybean gall midge, tar spot, red crown rot, southern rust, and Physoderma will be discussed.
    Session D - Wednesday, 1:00 PM - 1:50 PM
    Session E - Wednesday, 2:00 PM - 2:50 PM

  • 14. Fungicide considerations for soybean (1.0 PM)

    Daren Mueller, associate professor and extension crop plant pathologist, Plant Pathology and Microbiology, Iowa State University, Ames, IA

    Session B - Wednesday, 10:00 AM - 10:50 AM

  • 16. Update on the soybean cyst nematode situation (1.0 PM)

    Gregory Tylka, professor, Plant Pathology and Microbiology, Iowa State University, Ames, IA

    The soybean cyst nematode (SCN) is a major yield-reducing pathogen of soybean and is widespread in Iowa. The resistance currently contained in 95% of soybean varieties has been used in resistant varieties for decades and has lost much of its effectiveness. Also, SCN reproduction in fields where soybeans were grown in 2021 likely was much greater than normal due to the hot, dry growing season. This presentation with include information on the current situation with SCN in Iowa and surrounding states and discussion of prospects for control of the pest in future years.
    Session B - Wednesday, 10:00 AM - 10:50 AM
    Session C - Wednesday, 11:00 AM - 11:50 AM

  • 17. A summary of research results with dicamba (1.0 PM)

    Kevin Bradley, professor, Plant Sciences, University of Missouri, Columbia, MO

    This session will provide a summary of several ongoing and recently completed university research projects related to off-target movement of dicamba. The environmental factors that are most likely to influence off-target movement will be discussed, along with future recommendations.

  • 18. Sociological and human dimensions of herbicide resistance evolution and management (1.0 PM)

    Katherine Dentzman, assistant professor, Rural Sociology, Iowa State University, Ames, IA

    If herbicide resistance were merely a chemical, biological, or agronomic problem it likely would have been solved long ago. However, there are also humans involved-humans that make decisions, face barriers, and have access to different skills, knowledge, and capitals. Come hear from a sociologist on why the 'human factor' will be key to manage resistance issues and preserve herbicides as a useful agronomic tool.
