Weed Impede® herbicide is a preemergence surface-applied product for the control of many annual grasses and broadleaf weeds in ornamental plantings, rock gardens, ornamental bedding plants, bulbs, ground covers/perennials and established warm-season turfgrass.
Weed Impede® is orange in color and may cause temporary discoloration of sprayed surfaces.
Weed Impede® controls weeds growing from seed. Weed Impede® will not control emerged weeds. It does not control established weeds, weeds growing from stolens, rhizomes, or root pieces. Therefore, areas to be treated should be freeof emerged weeds. Weed residues, pruning and trash should be thoroughly mixed into the soil or removed prior to treatment.
