Grass control is challenging for Mississippi growers. Italian ryegrass, which is resistant to glyphosate, clethodim, and ALS-inhibiting herbicides, is common in the Delta area of the state. Complete control of dense populations of Italian ryegrass requires multiple herbicide applications. Summer annual grass control can be influenced by nozzles, spray mixtures, and application volume. Severe infestations of summer annual grasses should be managed as a primary target.
