Welcome to the Fourth IPM Podcast for Field Crops – 2019
Dr. Koch discusses the population growth of soybean aphid so far this year and the continued use of the 250-aphid treatment threshold to prevent aphid populations from reaching economically levels. Ongoing insecticide resistance issues and new insecticide options are also reviewed.
Soybean gall midge (SGM) is a new soybean pest in MN, and has been causing significant damage in Rock County in southwestern MN in 2018, and now in 2019. Koch describes what to look for when determining if soybean gall midge is present in a field, the type of damage it causes, how to respond if SGM is found and current research in to possible control tactics.
