WEEDY GRASSES CONTROLLED
This product kills most annual and hard-to-kill perennial grasses up to 1 foot high, including the following examples, in one or two applications. Younger, actively growing seedling weeds are more easily killed than older, mature, well-established grassy weeds that may require a repeat application for control. Adding oil concentrate may help control grassy weeds.
Barnyardgrass, Bermudagrass, Broadleaf Signalgrass, Crabgrass (Large & Smooth), Fall Panicum, Foxtail (Giant, Green & Yellow), Goosegrass, Johnsongrass (Seedling & Rhizome), Junglerice, Lovegrass, Orchardgrass (Seedling), Quackgrass, Tall Fescue Seedling, Texas Panicum, Shattercane/Wildcane, Wild Proso Millet, Wirestem Muhly, Witchgrass, Wooly Cupgrass
APPLICATION TIMING
Apply when grassy weeds are actively growing, not exceeding the minimum of days from application to harvest when used on vegetables and fruits. Warm sunny weather will accelerate systemic movement from leaves and stems down to the roots to give complete kill. DO NOT mow or cut off tops of weeds before spraying. DO NOT apply if rainfall is expected within one hour following application. Growth of treated grass stops soon after application. Grass turns yellow and dies within one to three weeks depending on the grass species, stage of growth and weather conditions. Cool weather, drought, and heat stress slow activity.
