Dick Sloan farms near Rowley in northeastern Iowa. For the past two years, he has conducted on-farm research on soybeans grown from neonicotinoid-treated and untreated seeds, and found no differences in yield. As a result, he has been able to cut input costs on his farm. Matt O’Neal, research entomologist at Iowa State University, will discuss recent research on the possible negative impacts of neonicotinoids, along with management alternatives for growers.

FARMINAR

• Neonicotinoid seed treatments in
soybean production are ubiquitous but
recent evidence has called their benefit
to yields and their ecological impact
into question.
• Farmer-cooperators compared soybean
yields from soybeans of the same variety
grown from neonicotinoid-treated
seeds and seeds not treated with a
neonicotinoid.
Key findings
• At each location, there was no measured
effect of seed treatment on
soybean yield.
• Given the lack of measured yield
benefit, the economic practicality of
neonicotinoid seed treatments can be
questioned.
