Description

Picolinafen is a selective herbicide belonging to the chemical class of pyridines. This compound is valued for its effective pre-emergence and early post-emergence control of broadleaf weeds in various cereal crops. It is a critical tool for agricultural professionals seeking reliable weed management solutions. The product is supplied as a high-purity technical material suitable for formulation into commercial agrochemical products.

Application

Picolinafen CAS NO 137641-05-5 is primarily used in the agricultural industry as a key active ingredient. Its main applications include:

• Pre-emergence Herbicide in Cereals: Used in wheat and barley for controlling weeds like cleavers, mayweed, and chickweed before they emerge.
• Early Post-emergence Weed Control: Applied in the early growth stages of cereal crops to manage established broadleaf weeds.
• Formulation into Crop Protection Products: Serves as the technical active ingredient for manufacturing various commercial herbicide formulations.
• Integrated Weed Management (IWM) Programs: Used in rotation or mixture with other herbicide modes of action to prevent herbicide resistance.
• Broadleaf Weed Control in Legumes: In some regions, used in leguminous crops under specific registered use patterns.
