Control of grass weeds in grain sorghum is accomplished through the use of soil applied herbicides.  Rainfall, irrigation, or physical incorporation is required to activate the herbicide that provides grass control.  Currently, herbicides for broadcast postemergence grass control in grain sorghum do not exist.  An acetolactate synthase (ALS) resistant grain sorghum hybrid was developed at Kansas State University.  Weed control programs involving combinations of atrazine, S-metolachlor, dicamba, and a corn herbicide ‘Steadfast’ (nicosulfuron + rimsulfuron) were established for grass and broadleaf weed control in ALS resistant grain sorghum at Manhattan, Belleville, Topeka, Hutchinson, Hesston, Parsons, Garden City, Tribune, and Dodge City, KS.  Field days were held at the various locations to discuss and show sorghum growers the new postemergence grass control option in grain sorghum.  Potential for crop injury and weed species controlled were discussed.  Grower perception of the program will be discussed.
