Description

Oxadiazon is a selective pre-emergence herbicide belonging to the oxadiazole chemical class. It is valued for its long-lasting residual activity and effectiveness against a broad spectrum of grassy and broadleaf weeds in various crops. This product is essential for agricultural professionals and formulators seeking reliable weed control solutions. Oxadiazon CAS NO 19666-30-9 is a key active ingredient in modern integrated pest management programs.

Application

Oxadiazon is primarily used as a herbicide in agriculture and horticulture. Its key applications include:

• Rice Paddy Weed Control: Selective pre-emergence and early post-emergence control of annual grasses, sedges, and broadleaf weeds.
• Turf and Ornamental Management: Used on golf courses, lawns, and ornamental nurseries to prevent weed establishment.
• Fruit and Vineyard Crops: Applied in citrus groves, vineyards, and tree fruit orchards for residual weed management.
• Industrial Vegetation Management: Control of unwanted vegetation in non-crop areas such as roadsides and utility rights-of-way.
• Agricultural Formulations: Serves as the active ingredient in the manufacture of emulsifiable concentrates (EC), wettable powders (WP), and granular (GR) herbicide formulations.
