Description

Metribuzin is a selective, systemic herbicide belonging to the triazinone chemical class. It is valued for its effective pre- and post-emergence control of a broad spectrum of annual grasses and broadleaf weeds in key agricultural crops. This product is essential for agronomists and formulators in the crop protection industry seeking reliable and efficient weed management solutions.

Application

• Selective Herbicide in Agriculture: Primarily used for weed control in soybean, potato, and sugarcane fields.
• Pre-emergence Application: Applied to soil before weed seeds germinate to create a protective barrier.
• Post-emergence Application: Used for controlling early-stage weeds in certain tolerant crops.
• Industrial & Non-Crop Areas: Employed in managed turf, forestry, and other non-agricultural vegetation control programs.
• Formulation Ingredient: Serves as the active ingredient in the manufacture of various wettable powder (WP), suspension concentrate (SC), and granular (GR) herbicide formulations.
• Integrated Weed Management (IWM): A key component in strategies to combat herbicide resistance and maintain crop yield.
