Thrips are a common but relatively minor pest of soybeans. They are most serious early in the season in fields that are also suffering drought stress.
Soybean thrips feed by scraping the underside of leaves then drinking the plant juices. The impact of this feeding is most severe on young plants that are suffering drought stress.
Insecticides are available for treating soybean thrips, but are rarely economically justified. Always read and follow all label instructions.
