Description

Diflufenican is a highly effective pre- and early post-emergence herbicide belonging to the chemical class of pyridinecarboxamides. Its primary value lies in providing long-lasting, residual control of a broad spectrum of grass and broadleaf weeds in key agricultural crops. This compound is essential for agronomists and formulators in the crop protection industry seeking to develop robust, selective herbicide solutions. Diflufenican CAS NO 83164-33-4 is a cornerstone active ingredient for integrated weed management programs globally.

Application

Diflufenican is a selective herbicide with systemic and residual activity, widely used in various agricultural formulations.

• Cereal Herbicides: Primary use in wheat, barley, rye, and triticale for control of key weeds like black-grass, cleavers, and poppy.
• Oilseed Rape Protection: Formulated for pre- and post-emergence weed control in winter oilseed rape crops.
• Legume Crop Solutions: Used in peas and beans as part of a mixture for broad-spectrum weed management.
• Industrial Vegetation Management: Employed in non-crop areas for total vegetation control.
• Formulation Intermediate: Serves as a key technical material for manufacturing wettable powders (WP), suspension concentrates (SC), and emulsifiable concentrates (EC).
• Synergistic Herbicide Mixtures: Commonly combined with other actives like isoproturon or pendimethalin to enhance the spectrum of control and manage resistance.
