Description

Carfentrazone-Ethyl is a selective, post-emergence herbicide belonging to the phenyl triazolinone chemical class. It is valued for its rapid action and effectiveness against a broad spectrum of broadleaf weeds, including those resistant to other herbicide groups. This compound is essential for agricultural professionals and formulators seeking reliable weed control in key crops such as cereals, corn, soybeans, and turf.

Application

Carfentrazone-Ethyl is a key active ingredient in modern agricultural chemistry, primarily used for post-emergence weed management. Its specific applications include:

• Broadleaf Weed Control in Cereals: Effective management of weeds like kochia, pigweed, and lambsquarters in wheat, barley, and oat fields.
• Soybean and Corn Production: Used in herbicide mixtures to control challenging broadleaf weeds without harming the crop.
• Turf and Ornamental Management: Formulated for use on golf courses, lawns, and in ornamental nurseries to eliminate unsightly weeds.
• Industrial Vegetation Management: Applied in non-crop areas such as rights-of-way, fence lines, and around industrial sites.
• Desiccant and Harvest Aid: Used to dry down certain weed species and crop canopy to facilitate a more uniform harvest.
• Resistance Management Programs: A vital tool in rotation to manage and prevent herbicide-resistant weed populations.

Quality Control

Our Carfentrazone-Ethyl technical material is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing to ensure it meets precise specifications for identity, potency, and impurity profiles. A Certificate of Analysis (COA) detailing assay (typically ≥95% by HPLC), relevant impurities, and physical properties is provided with each shipment to guarantee consistency and performance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Keep away from heat, sparks, and open flame. Ensure the container is kept upright to prevent leakage.
