Dicamba is an herbicide used to control annual and perennial broadleaf weeds. In 2016, Monsanto first commercialized genetically engineered (GE) dicamba-tolerant (DT) cotton seeds. The genetic engineering process inserts into a plant’s genome genes with beneficial traits, such as the ability to tolerate herbicide applications. DT cotton varieties were developed by inserting a bacterial gene that enables them to survive dicamba applications. Since 2016, cotton farmers have widely adopted DT cotton seeds.
