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.
