Description

(Z)-Pyriminobac-Methyl is a selective post-emergence herbicide belonging to the pyrimidinyloxybenzoic acid chemical class. This compound is valued for its high efficacy in controlling a broad spectrum of grass and sedge weeds in paddy rice fields. It is an essential tool for agricultural professionals and formulators seeking reliable crop protection solutions. The product is supplied as a technical-grade material for the manufacturing of commercial herbicide formulations.

Application

This active ingredient is primarily utilized in the agrochemical industry for the development of advanced crop protection products.

• Selective Herbicide for Paddy Rice: Core application for post-emergence control of annual and perennial grass weeds (e.g., barnyardgrass, sprangletop) and sedges.
• Agrochemical Formulation: Used as a technical material in the production of emulsifiable concentrates (EC), suspension concentrates (SC), and wettable powders (WP).
• Integrated Weed Management (IWM): A key component in resistance management strategies, often used in rotation or mixture with other herbicide modes of action.
• Crop Safety Enhancement: Formulated to maximize weed control while maintaining safety for transplanted and direct-seeded rice.
• Global Rice Production: Supports high-yield rice cultivation in major producing regions across Asia and the Americas.
