Herbicides other than glyphosate, such as dicamba, are increasingly being used to control tolerant weeds, according to a new report from the USDA Economic Research Service.
In 2018, about 43% of U.S. soybean acreage was planted with dicamba-tolerant seeds. The states with the most use were Mississippi (79% of soybean acreage), Tennessee (71%) and Kansas (69%).
In 2006, almost 9 out of every 10 acres were planted with glyphosate-tolerant seeds. By 2018, glyphosate-tolerant weeds were identified in the majority of soybean-producing states.
