Host plant resistance for soybean aphid is a management tool to protect yield. Our lab has evaluated the efficacy and of host plant resistance but generally with small plot research. Working with Iowan farmers, we evaluated the efficacy of aphid-resistant soybean on commercial farms in Iowa. With funding from the North Central Region – Sustainable Agriculture Research and Education Program, we are studying the potential for aphid-resistant soybeans on a larger scale. We provided farmers with experimental and commercially available soybean varieties containing a 2-gene pyramid (Rag1+2). Read more about On-farm evaluation of aphid-resistant soybeans

Sustainable management of host plant resistance for soybean aphid

Project

With funding from the North Central Soybean Research Program, we are determining if aphid-resistant soybeans can be use with a “refuge-in-a-bag” or RIB. Refuges of pest-susceptible varieties are often included when a pest-resistant variety of a crop is used. By including a refuge, we can produce a population of avirulent aphids so that they can inter-breed and swamp out the genes of virulent aphids that are capable of surviving on the aphid-resistant soybeans.

Extension

Page

Our extension program is led by Dr. Erin Hodgson, and Dr. O’Neal and many lab members also participate in programs throughout the year. We are focused on delivering research-based information to a variety of clientele. Our group serves farmers, crop consultants, agricultural professionals and other university/extension personnel. Most of our programs are within the state of Iowa, but we travel throughout the Midwest to deliver content. Read more about Extension
