As harvest season ends one issue that soybean producers are concerned about is the dicamba herbicide.

According to a recent study from the Iowa Soybean Association, less than a third of farmers expect their yields to be negatively affected by dicamba, but it was at the top of the list of concerns for the 2018 growing season. Dicamba is a weed killer that is sprayed over the top of soybean fields. Iowa soybeans have typically been tolerant to it, according to American Soybean Association Vice President and Keota farmer John Heisdorffer, but there are some parts of the U.S. that have seen dicamba’s negative effect, “It’s the non-tolerant ones that are having the problem. So when it drifts over to them it causes the leaves to kind of look like crinkly and cupping up, but it can also completely kill the soybeans if they’re in the right stage.”

Heisdorffer says dicamba has had a larger problem in southern states like Arkansas, Kentucky, and Tennessee, and the ASA directors from that area have formed a task force with industry leaders and universities to determine the cause of the issue. The ASA board of directors will discuss dicamba at their meeting this week.
