Description

Carfentrazone-Ethyl is a selective, post-emergence herbicide belonging to the aryl 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 a critical active ingredient for agricultural professionals and formulators seeking reliable weed control in major row crops, turf, and non-crop areas.

Application

Carfentrazone-Ethyl is primarily utilized as a herbicide active ingredient. Its key applications include:

• Broadleaf Weed Control in Cereals: Effective management of key weeds like cleavers, mayweed, and chickweed in wheat, barley, and other cereal crops.
• Soybean and Cotton Desiccation/Aid: Used as a harvest aid or desiccant to control late-season weeds and facilitate uniform crop maturation and harvesting.
• Turf Management: Control of tough broadleaf weeds such as dandelion, clover, and plantain in professional turf settings like golf courses and sports fields.
• Industrial Vegetation Management: Management of vegetation along rights-of-way, fence lines, and other non-crop industrial areas.
• Pre-plant and Burndown Applications: Used in no-till and reduced-till systems to control existing vegetation before planting crops like corn and soybeans.
• Formulation Component: A key ingredient in the production of various emulsifiable concentrate (EC) and suspension concentrate (SC) herbicide formulations.
