Summary: Stephenson addresses the factors involved in the poor control of grass in corn, cotton, and soybean that occurred during 2019 in the states of Tennessee, Mississippi, and Louisiana. He reviews the history of grass control and the resistance that has developed among various types of grass, such as johnsongrass. He also identifies reasons for the failure to control grasses in 2019, including poor coverage and poor environmental conditions. Stephenson concludes by making recommendations for herbicide use to control grass.
