Spectracide Weed & Grass Killer with Extended Control Concentrate

Spectracide® Weed & Grass Killer with Extended Control Concentrate

This product is a non-selective herbicide that will kill any vegetation contacted and will prevent re-growth for up to 3 months. It enters plants through the leaves and moves down to the roots. This will ensure that the entire plant is eliminated. It also provides a protective barrier that prevents weeds and grasses from emerging for up to three 3 months. 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 plants with water immediately.
