URBANA, Ill — Every year, University of Illinois scientists conduct pest and disease surveys in corn and soybean crops across the state, along with in-field tests of insecticides, seed treatments, and more. The 2022 report, now available, describes ongoing Bt-resistance monitoring results; field evaluations of traits and insecticides for controlling corn rootworm; results of insect pest surveys, including dectes stem borer, soybean gall midge, and rootworm adults; and a summary of weather and crop production for Illinois' 2022 growing season. 

"We invite farmers to use the report in guiding control decisions, tracking performance over time, and seeing trends in pest populations," says Nick Seiter, research assistant professor in the Department of Crop Sciences and Illinois Extension, both part of the College of Agricultural, Consumer and Environmental Sciences. Seiter is a co-author on the report.

The 2022 report is available on the Field Crop Insect and Disease Applied Research website, along with reports from past years.
