Farmers and crop specialists can hear updates from some of the nation’s leading agricultural researchers Dec. 1-2 at the 2020 University of Missouri Crop Management Conference.
Due to Missouri COVID-19 restrictions, this year’s conference is offered live online, said MU Extension weed scientist Kevin Bradley.
Technology discussions lead the conference.
Bradley tells about MU research on electrocuting weeds and grinding seeds to reduce herbicide-resistant weeds. The Seed Terminator and the Weed Zapper are designed to prevent seeds from returning to the soil. Conventional U.S. agriculture has not adopted these nonconventional weed management tools and practices, but Bradley said the technology deserves a look.
Speakers also look at how technology is affecting multiple generations of farmers on the same farm. MU researchers discuss advances in planter technology that allow different planting depths in highly variable soils.
Extension specialists also offer sessions on emerging pests and diseases such as tar spot in corn, which has been confirmed in four Missouri counties. Discussions on how to scout for and detect tar spots can help producers manage this rapidly spreading disease.
Crop experts from three Midwestern universities will discuss research on the effects of too much potassium and improper timing of application.
A valid email address, internet access, and the ability to play audio and view presentations are required to participate. Certified Crop Adviser credits are available.
