Understanding life cycle assessments with Dr. Rosentrater
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.

Drs. Matt O’Neal and Erin Hodgson created a podcast to promote IPM concepts, like identification, sampling, economic thresholds, and insecticide efficacy. They also talk about updates on invasive pests and regulatory news, and translate new research relative to insects in agriculture.
