Description

Benzofenap CAS NO 82692-44-2 is a selective pre- and early post-emergence herbicide belonging to the benzoylpyrazole chemical class. It is valued for its effective control of a broad spectrum of annual grasses and broadleaf weeds in key agricultural crops. This compound is primarily utilized by the agrochemical industry for the formulation of crop protection products, specifically targeting rice and turf management.

Application

• Rice Herbicide: A key active ingredient in selective herbicides for paddy rice, controlling weeds like barnyardgrass and sedges.
• Turf Management: Used in professional turf care products for golf courses and sports fields to manage invasive grassy weeds.
• Agrochemical Formulations: Serves as a critical component in the manufacturing of emulsifiable concentrates (EC) and suspension concentrates (SC).
• Pre-emergence Weed Control: Applied to soil to prevent weed germination and establishment in target crops.
• Post-emergence Weed Control: Used for early post-emergence application to control young, actively growing weeds.
• Industrial R&D: Supplied as a high-purity reference standard or intermediate for research and development of novel agrochemicals.
