You are invited to attend the Corn & Soybean Pest Management Field Day on Wednesday, August 31, 2022 from 9:00 a.m. to 12:30 p.m. at the Southwest Research and Outreach Center. There is no fee to attend. Pre-registration is preferred by Friday, August 26 and will ensure a meal. Registration will occur from 8:30 a.m. to 9:00 a.m. with a field tour from 9 am - 12 pm to view current research plots. Lunch will follow the conclusion of the tour. In case of inclement weather, the speakers will present inside. Certified Crop Advisor credits in Integrated Pest Management (3 credits) will be available for participants.
8:30 - Registration
9:00 - Corn rootworm management
Bruce Potter, Extension Integrated Pest Management Specialist, will lead a tour of corn rootworm research on corn rootworm management options. The discussion will center on attendee observations and questions. The session will focus on a review of soil insecticides, and transgenic traits, including currently available pyramids of Bt traits and the newest available trait package, SmartStax Pro, scouting, and the implications of Bt resistance and weather on the status of rootworm populations
10:00 - Soybean cyst nematode management
Dr. Seth Naeve, Extension soybean agronomist, will discuss soybean cyst nematode (SCN) management. A focus will be on resistance management and the common virulence on the most common source of genetic SCN resistance available to farmers. Naeve will discuss awareness (soil sampling) and management strategies (variety selection and seed treatments) for SCN. Naeve will also provide insight on the interactions between SCN and another common malady - iron deficiency chlorosis (IDC).
11:00 - Weed management techniques
Dr. Debalin Sarangi, Extension weed scientist, will lead a tour of weed research plots. Sarangi will present information on corn and soybean weed management research and the status of herbicide resistance in Minnesota. Weed research plots on the timing and efficacy of PRE and POST herbicide applications and herbicide resistance will be topics for discussion. The focus will be on strategies to optimize weed control and delay the development of herbicide resistance.
12:00 - Lunch
