Ento Students in the Field

Bob Koch[2/1/2016]More than half of all U.S. soybean farmers use seeds coated with an insecticide meant to protect the plant from its ­biggest foes. But a new report from a dozen public universities, including the University of Minnesota, says the coatings are providing few if any benefits in most cases, while raising expenses for farmers and affecting the surrounding environment in negative ways... a co-author, University of Minnesota entomologist Bob Koch , said neonicotinoid coatings are effective in suppressing a few insects other than soybean aphids, but those are rarely a problem for farmers in northern states where most of the nation's soybeans are grown.

Bob Koch[1/12/2016] MINNEAPOLIS, Minn. — Neonicotinoid seed treatments are used on a large percentage of soybean acres. However, the value of these treatments was questioned in a 2015 EPA report. In response, field crops entomologists from 12 northern states, including Robert Koch and Bruce Potter from the University of Minnesota, collaborated to create a new multipage extension publication, entitled The Effectiveness of Neonicotinoid Seed Treatments in Soybean, which explains the role of neonicotinoid seed treatments in northern soybean.

Neonicotinoid seed treatments can be a useful tool for management of some early-season soybean pests in targeted high-risk situations. However, the current widespread use of these treatments exceeds the risk posed by pests and may cause adverse consequences, such as impacts to beneficial organisms, such as predatory insects, and lead to development of pest resistance. For the full discussion, see The Effectiveness of Neonicotinoid Seed Treatments in Soybean.
