Pendimethalin 30% EC is a selective, dinitroaniline herbicide used pre-emergence and sometimes post-emergence to control annual grasses and certain broadleaf weeds by inhibiting cell division and elongation. The 30% EC indicates it is an Emulsifiable Concentrate formulation containing 30% active ingredient, which means it mixes with water to form a sprayable liquid. It is applied before weeds and crops emerge to form a protective layer on the soil, preventing weed germination.
