How do I control johnsongrass (Sorghum halepense) in turfgrass in Roanoke County Virginia?
Website Resources: http://sorghum.halepense.turfweeds.net http://www.ppws.vt.edu/scott/weed_id/sorha.htm Recommendation: Apply MSMA or DSMA at 10-day intervals as needed when plants are still young and maintain a routine mowing program. Other postemergence chemicals include fenoxaprop, fluazifop, and sethoxydim but can only be used in certain types of turfgrass. Read and follow label instructions. Brief yellowing is to be expected from MSMA or DSMA treatments but turfgrass should recover.
