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.

Today, Matt and Erin talk about the recent EPA proposal to revoke all tolerances to chlorpyrifos. This insecticide is an option in corn and soybean in Iowa and restricting or removing the use could have potential implications for field crop pest management. Matt shares a paper that shows a decrease of chlorpyrifos in corn but relatively steady use in soybean (doi:10.1088/1748-9326/10/9/094016). He isn't sure if revoking the use would have an immediate impact, but Erin offers a Coke analogy to say otherwise.
