Description

Metolachlor CAS NO 51218-45-2 is a selective pre-emergence herbicide belonging to the chloroacetamide chemical class. It is a critical active ingredient for controlling a broad spectrum of annual grasses and certain broadleaf weeds in major field crops. This product is essential for agricultural professionals and formulators seeking reliable, high-purity active ingredients for crop protection solutions. Its primary use is in the cultivation of corn, soybeans, peanuts, and cotton, where effective soil-applied weed management is paramount for yield protection.

Application

• Selective Herbicide for Major Row Crops: Primarily used for pre-emergence control of weeds in maize (corn), soybean, cotton, and peanut fields.
• Grass and Broadleaf Weed Management: Effective against annual grasses like foxtails, barnyardgrass, and crabgrass, as well as small-seeded broadleaf weeds such as pigweed and lambsquarters.
• Agricultural Formulations: Serves as the key technical material for manufacturing emulsifiable concentrate (EC), suspension concentrate (SC), and granular (GR) herbicide formulations.
• Soil-Applied Weed Control: Applied to the soil surface and activated by rainfall or irrigation, forming a protective barrier that inhibits weed seed germination and early seedling growth.
• Integrated Pest Management (IPM) Programs: A cornerstone chemical for rotational and tank-mix strategies to manage herbicide resistance and ensure long-term field efficacy.
