Description

Piperophos is a selective organophosphorus herbicide belonging to the thiolcarbamate chemical class. This compound is valued for its effective pre- and early post-emergence control of grassy weeds in key agricultural systems. It is primarily utilized by the agrochemical industry for formulating crop protection products. Piperophos CAS NO 24151-93-7 is a critical active ingredient for ensuring crop yield and quality.

Application

• Selective Herbicide in Rice Cultivation: Primarily used for controlling annual grasses and sedges, such as barnyard grass, in paddy rice fields.
• Pre-emergence Weed Control: Applied to soil before weed seeds germinate to create a protective barrier against grassy weeds.
• Early Post-emergence Application: Effective for managing young weed seedlings in their early growth stages.
• Formulation Intermediate: Serves as a key technical-grade active ingredient for manufacturing emulsifiable concentrates (EC), wettable powders (WP), and granular (GR) herbicide formulations.
• Integrated Pest Management (IPM): Used in rotation with other herbicide modes of action to manage and prevent herbicide resistance.
• Turf and Ornamental Management: Employed in professional turf management for certain grass species (subject to local regulatory approval).
