Casoron 50lb Bag

Casoron 4G controls weeds underground, before they emerge, by forming an herbicidal vapor barrier in the upper layer of soil when activated by rainfall or irrigation water. Existing weeds rooted in this vapor barrier soon die off and any weed seeds germinating in or below the barrier are killed when new roots and shoots contact the vapor barrier. Deep-rooted perennial weeds are prevented from emerging. Plants with roots below the barrier are not harmed.
