Description

Oxadiazon Methoxy CAS NO 19666-31-0 is a selective pre-emergence herbicide belonging to the oxadiazole 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 a critical agrochemical input for agricultural producers and formulators seeking reliable, long-lasting residual weed management.

Application

• Selective Herbicide in Agriculture: Primarily used as a pre-emergence herbicide for weed control in crops such as rice, turf, and certain fruit orchards.
• Turf and Ornamental Management: Applied in the maintenance of golf courses, lawns, and ornamental landscapes to prevent weed germination.
• Industrial Vegetation Control: Utilized in non-crop areas like roadsides, railways, and utility rights-of-way for total vegetation management.
• Agrochemical Formulation: Serves as the active ingredient in the manufacturing of various commercial herbicide formulations, including wettable powders (WP) and granules (GR).
• Research & Development: Used as a reference standard or intermediate in agricultural chemical research for developing new crop protection solutions.
