Description: 

Matt and Erin recap a presentation made at ICM Conference this week. Bob Koch (University of Minnesota) talked about bifenthrin failures to soybean aphid in southern Minnesota in 2015. He performed bioassays and detected resistance. The level of resistance was low, but provides the first example of this pest overcoming a pyrethroid in the field. Bob's ICM proceedings article summarizes highlights how resistance happens and strategies for prolonging insecticide efficacy.
