  • Applications

    Dichlobenil (CAS 1194-65-6) is a soil-applied pre-emergence herbicide used to control weed growth in agricultural crops and ornamental horticulture. Typical applications include weed control in crop production and nursery stock production; weed management in vineyards and fruit-tree orchards; turf management for lawns and golf courses; and use in greenhouses or potted-plant production, with granular formulations applied to soil before weed emergence.
