Description

Pyrazoxyfen is a selective herbicide belonging to the pyrazole chemical class, known for its effective pre-emergence and early post-emergence control of annual grasses and broadleaf weeds. Its primary value lies in providing reliable, long-lasting residual activity in key agricultural systems, helping to secure crop yields and quality. This product is essential for formulators and distributors serving the global agrochemical industry, particularly for use in rice paddies and other field crops.

Application

• Primary use as a selective herbicide for pre-emergence and early post-emergence weed control in rice cultivation.
• Formulation into various end-use products such as wettable powders (WP), suspension concentrates (SC), and granules (GR).
• Control of problematic annual grasses (e.g., barnyardgrass) and broadleaf weeds in paddy fields.
• Integration into integrated pest management (IPM) programs to manage herbicide resistance.
• Use in the production of combination herbicide products for broader-spectrum weed control.
• Supplying agrochemical manufacturers and formulators for the production of crop protection solutions.
