Description

Pretilachlor is a selective pre-emergence herbicide belonging to the chloroacetamide chemical class. Its primary value lies in its effective control of annual grasses and broadleaf weeds in transplanted rice, ensuring higher crop yields and quality. This product is essential for agricultural chemical manufacturers, formulators, and distributors serving the global rice cultivation industry. We supply high-purity Pretilachlor CAS NO 51218-49-6 to meet the stringent demands of modern agrochemical production.

Application

Pretilachlor is a cornerstone active ingredient in selective herbicide formulations, primarily for rice agriculture. Its key applications include:

• Transplanted Rice Herbicide: As a pre-emergence treatment to control weeds in paddy fields.
• Granular Formulations (GR): Used in the production of easy-to-apply granular products for direct application in flooded fields.
• Emulsifiable Concentrate (EC) Formulations: A key component in liquid formulations for dilution and spray application.
• Control of Annual Grasses: Effectively targets barnyard grass, sprangletop, and other problematic grass weeds.
• Control of Sedges and Broadleaf Weeds: Manages weeds such as Cyperus species and certain broadleaf weeds in rice.
• Integrated Pest Management (IPM) Programs: Used as part of a rotational strategy to prevent herbicide resistance.
