Description

Methazole CAS NO 20354-26-1 is a selective pre-emergence and post-emergence herbicide belonging to the benzothiadiazole chemical class. It is valued for its effective control of a broad spectrum of annual grasses and broadleaf weeds in various crops. This compound is primarily utilized by the agrochemical industry for the formulation of crop protection products. Its reliable performance makes it a key component in integrated weed management programs.

Application

• Agrochemical Formulations: Primary use as a key active ingredient in selective herbicide products.
• Crop Protection: Effective pre- and post-emergence control of weeds in crops such as cotton, soybeans, and peanuts.
• Broadleaf Weed Management: Targets problematic broadleaf weeds including pigweed, lambsquarters, and velvetleaf.
• Grass Weed Suppression: Controls annual grasses that compete with cash crops for nutrients and sunlight.
• Industrial Vegetation Management: Used in non-crop areas for general vegetation control.
• Research & Development: Serves as a reference standard or intermediate in agricultural chemical research.
