No Need to Spray for Soybean Aphids This Season
Soybean harvest underway in northeastern Kansas

Soybean aphid levels in northeastern Kansas have decreased to extremely low levels with the increasingly cool weather.

Scott Beguelin, Crop Quest Area Manager, based in Silverlake, Kan., notes that area producers didn’t spray for aphids prior to harvest. Decreased insect pressure should encourage yields in the area, but the consultant says that area producers haven’t received much yield indication from the small amount of soybeans harvested so far.

Beguelin estimates that about 80% of soybeans planted in the northeastern Kansas area have turned or dropped leaves. The U.S. Department of Agriculture (USDA) Oct. 5, 2003 Crop Progress Report notes that only about 10% of the Kansas soybean crop has been harvested.

“We’re right about where we expected to be, Beguelin says. “Next year, if the populations come in earlier, we could see higher levels of soybean aphid infestation. This year, we were able to reach harvest without spraying for aphids.
