Product Q&A

Answer:

Casoron 4G Herbicide is a pre-emergent herbicide that would control weeds before they emerge from the ground by forming an herbicidal vapor barrier in the upper layer of the soil when activated by rainfall or irrigation. We recommend that it should be applied before weed seed germination and emergence from the soil (usually from mid-winter to early spring).
