Description

Pyraflufen Ethyl is a highly effective aryloxyphenoxypropionate herbicide, specifically a protoporphyrinogen oxidase (PPO) inhibitor. This mode of action makes it a critical tool for pre- and post-emergence control of a broad spectrum of broadleaf weeds in major row crops. It is essential for agricultural professionals and formulators seeking a reliable, fast-acting solution with excellent crop safety. Its primary use is in global agriculture for weed management programs in crops such as cereals, soybeans, and cotton.

Application

• Selective Herbicide in Cereals: For post-emergence control of key broadleaf weeds like cleavers, chickweed, and mayweed in wheat, barley, and other cereal crops.
• Soybean and Cotton Desiccant/Aid: Used as a harvest aid or desiccant to dry down weeds, facilitating a cleaner and more efficient harvest.
• Broadleaf Weed Control in Legumes: Effective management of problematic weeds in pea, lentil, and bean crops.
• Industrial Vegetation Management: Component in non-crop area herbicides for controlling unwanted vegetation along railways, fence lines, and industrial sites.
• Tank-Mix Partner: Enhances the spectrum and efficacy of other herbicides when used in combination, helping to manage herbicide-resistant weed populations.
• Formulation Intermediate: Sourced by agrochemical companies for the manufacture of proprietary emulsifiable concentrate (EC) and suspension concentrate (SC) formulations.
