There’s been widespread cupping of soybean leaves across the Northern Plains this summer. University of Minnesota Extension Agronomist Seth Naeve a number of things may be causing the damage, including dicamba. “Whether it was drift, volatilization or soybeans that were less tolerant, those are the things that are around the edges we’ll have to figure out.” At the end of July, Minnesota’s dicamba drift complaints were in-line with the same time last year, but that number is increasing. On August 2, the Minnesota Department of Agriculture had 119 dicamba drift complaints. Dicamba complaints are also showing up in the Dakotas, but the number of complaints are lower. As of August 2, the South Dakota Department of Agriculture has 14 alleged dicamba incidents, close to last year’s 17 total complaints. North Dakota had seven formal complaints, a few shy of the 11 total complaints from 2020.
