OHP Inc. 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.
