Description

Chlorotoluron is a selective, systemic phenylurea herbicide widely used for pre- and post-emergence weed control. Its primary value lies in effectively managing a broad spectrum of annual grasses and broadleaf weeds in key cereal crops, contributing to higher agricultural yields. This product is essential for agricultural professionals and formulators seeking reliable residual activity and crop safety in wheat, barley, and rye cultivation systems.

Application

• Cereal Crop Protection: Pre- and post-emergence control of weeds in winter and spring wheat, barley, and rye.
• Broad-Spectrum Weed Management: Effective against key problem weeds including black-grass, annual meadow-grass, chickweed, and cleavers.
• Agricultural Formulations: A key active ingredient in the manufacturing of suspension concentrates (SC), wettable powders (WP), and other commercial herbicide formulations.
• Integrated Weed Management (IWM) Programs: Used in rotation or tank mixes with other herbicide modes of action to prevent and manage herbicide resistance.
• Non-Selective Vegetation Control: Used in industrial and non-crop areas for total vegetation management, subject to local regulatory approvals.
