Description

Pyraclonil is a selective herbicide belonging to the chemical class of pyrazole derivatives. This compound is valued for its effective pre-emergence and early post-emergence control of a broad spectrum of weeds in key agricultural systems. It is primarily needed by agrochemical manufacturers and formulators developing crop protection solutions for rice paddies and other field crops. Its specific mode of action makes it a valuable tool in integrated weed management programs.

Application

• Primary Use in Rice Cultivation: Pre-emergence and early post-emergence control of annual grasses, sedges, and broadleaf weeds in transplanted and direct-seeded rice.
• Agrochemical Formulation: A key active ingredient in the manufacture of suspension concentrates (SC), wettable powders (WP), and granular (GR) herbicide formulations.
• Weed Resistance Management: Used in rotation or mixture with other herbicide modes of action to mitigate and manage herbicide-resistant weed populations.
• Broad-Spectrum Weed Control: Effective against problematic weeds such as barnyardgrass, sedges, and certain broadleaf species that compete with crops.
• Industrial & Non-Crop Areas: Potential application for vegetation management in non-agricultural settings, subject to local regulatory approvals.
• Research & Development: Serves as a reference standard or intermediate in agricultural chemical research for developing new crop protection agents.
