HDX Weed and Grass Killer Concentrate kills unwanted plants by inhibiting the production of a substance found only in plants. It enters through the sprayed foliage and moves down to the roots. Avoid direct spray or drift onto desirable plants, lawn grasses, shrubs and trees. Protect desirable plants and vegetation with a piece of plastic or cardboard. If desirable plants are accidentally sprayed, wash with water immediately. Any HDX Weed and Grass Killer Concentrate that is not absorbed by the plant is broken down into natural materials. This product has no soil activity. Do not mow, cut or otherwise disturb treated vegetation for at least 7 days following application. Most treated weeds usually show initial symptoms in 2 to 4 days and complete kill in 1 to 2 weeks.
