Definite
Pre-Emergence Herbicide for Corn Weed Control

Definite is a selective herbicide designed for use on herbicide-tolerant and conventional field corn, offering early-season control of grass and broadleaf weeds. It combines acetochlor, clopyralid, and flumetsulam to disrupt weed germination and seedling growth. Ideal for pre-plant, pre-emergence, or early post-emergence applications, it helps optimize the timing of post-emergence herbicides like glyphosate or glufosinate. Definite provides soil residual control of weeds, ensuring effective management for enhanced crop protection.
