OHP, Inc. Weed and Grass Killer Casoron 4G

Casoron 4G is a pre-emergent herbicide which easily handles many troublesome weeds in and around established woody landscape ornamentals, non-crop areas, fruit and nut trees and respective nurseries. The active ingredient in Casoron 4G is dichlobenil, which acts by inhibiting germination, and actively dividing cells of meristems of growing points and root tips; thereby, inhibiting cell division through cellulose synthesis. Casoron 4G prevents weed seeds, emerging shoots and certain existing weeds from growing. Casoron 4G develops a vapor barrier and is active for 9-10 months after application. It is absorbed primarily from the soil by the root system. Casoron 4G requires ½ to 1 inch of overhead watering to thoroughly incorporate granules to a depth of 4-6 inches in the soil. Application timing is critical, since dichlobenil volatilizes under warm conditions. Applications should be made under cool weather conditions in late fall or very early spring. A fall application may be necessary to control certain perennials, such as fescues, orchardgrass, quackgrass, docks, and dandelions. Do not treat newly planted trees until at least 6 months after planting. Casoron 4G controls grasses and hard to control weeds such as Coltsfoot, Thistles (has post emergent activity), Horsetail, Nutsedge, and many other annual and perennial weeds.
