Understanding life cycle assessments with Dr. Rosentrater

Soybean Pest Podcast
Season:

Episode:

Description: 

Matt and Erin have a special guest on this podcast to help understand life cycle assessments. Dr. Kurt Rosentrater is an engineer and associate professor at Iowa State. Kurt explained the basics of conducting a life cycle assessment, including assumptions and resulting complications that come with this tool. They focused on a recent example looking at environmental impacts in four major crops. Here is the link to the paper so you can follow along with figures: http://www.ingentaconnect.com/content/iop/erl/2015/00000010/00000009/art094016. The assessment showed freshwater ecotoxicity impact in soybean increased 3-fold from 2002 to 2012. The authors claimed the insecticides used to control soybean aphid was an important factor. Corn, cotton and wheat did not have a significant increase of impact over the study duration.

Are soybean aphids becoming resistant?

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.
