Description

(E)-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 rice paddies. It is a critical tool for agricultural professionals and formulators seeking reliable crop protection solutions. Its specific mode of action makes it a key component in integrated weed management programs.

Application

• Primary Use in Rice Cultivation: Selective post-emergence control of barnyardgrass (*Echinochloa crus-galli*), sedges (*Cyperus* spp.), and other problematic annual grasses in transplanted and direct-seeded rice fields.
• Formulation Ingredient: Serves as the active ingredient in the manufacture of commercial emulsifiable concentrate (EC) and suspension concentrate (SC) herbicide formulations.
• Weed Resistance Management: Incorporated into weed control strategies to manage and prevent herbicide resistance due to its distinct site of action.
• Agricultural Research & Development: Used as a reference standard and analytical reagent in agrochemical R&D for metabolic studies, environmental fate analysis, and efficacy testing.
