This product controls most existing vegetation prior to renovating turfgrass areas or establishing turfgrass grown for seed or sod. It can also be used to control or suppress many winter annual weeds and tall fescue for effective release of dormant bermudagrass and bahiagrass turf. For annual weeds to be the most easily controlled, make sure to apply Glyphosate Plus when the weeds are small. Perennial weeds are most easily controlled when treated as the weed is nearing maturity.
