Description

L-Metalaxyl is a high-purity, single-enantiomer form of the systemic fungicide metalaxyl, specifically the L-(+)-enantiomer. This optically active form is recognized for its superior fungicidal activity and is a critical intermediate in the synthesis of advanced agricultural formulations. It is essential for manufacturers and formulators developing targeted crop protection solutions against soil and seed-borne diseases caused by Oomycete pathogens, such as Pythium and Phytophthora species. Its use is fundamental in ensuring crop health and yield for a wide range of agricultural commodities.

Application

• Primary Active Ingredient in advanced, enantiomerically pure fungicidal formulations.
• Seed Treatment for protecting crops like corn, soybeans, cotton, and vegetables from damping-off and root rot at the earliest growth stages.
• Soil Application for controlling Oomycete diseases in high-value horticultural crops, vineyards, and turfgrass.
• Intermediate in Agrochemical Synthesis for the production of metalaxyl-M (mefenoxam) and other chiral pesticide compounds.
• Research & Development as a standard reference material for analytical method development and biological efficacy studies.
• Formulation Blends combined with other fungicides or insecticides to create broad-spectrum crop protection products.
