To achieve the best results, apply Roundup® Super Concentrate Grass & Weed Control Herbicide when weeds, grasses, or brush are actively growing.

Do not spray in windy conditions. Do not spray to the point of run-off. Rain or watering two hours after application will not wash away effectiveness. However, heavy rainfall immediately after application may wash the chemical off the foliage and repeat treatment may be required. Do not apply if rainfall is forecast for the time of application. Avoid spray contact on desirable plants as any plant contacted may be controlled.
