For the past 5 years, we have evaluated insecticides for managing soybean aphids. The most recent report can be found at our website www.soybeanaphid.info. After applying insecticides as part of our 2009 insecticide evaluation, Erin and I discuss some issues to consider when selecting an insecticide
As soybeans reach the late reproductive stages the need to manage aphids decreases. However, aphids persist in soybean fields around the midwest. We discuss a couple factors that should be considered when applying insecticides this late in the year. Also, we re-count the spread of Japanese beetles in Iowa as a new herbivore of soybeans.
In the last episode of season 7, Matt and Erin talk about two new insecticide options for soybean aphid in Iowa. Movento and Sivanto by Bayer CropSciences are products that target fluid-feeding pests, like aphids, and are considered reduced-risk options compared to broad spectrum insecticides. Movento is a Group 23 and Sivanto is a Group 4D. To learn more about these insecticide groups, visit the IRAC website.
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
