Description

Diclofop-Methyl CAS NO 51338-27-3 is a selective post-emergence aryloxyphenoxypropionate herbicide. It is a critical active ingredient for the effective control of annual and perennial grass weeds in broadleaf crops. This compound is essential for agricultural chemical formulators and manufacturers targeting the cereal, soybean, and canola markets. Its mechanism of action provides reliable, systemic control, making it a cornerstone in modern integrated weed management programs.

Application

• Primary Use as a Herbicide: Formulated for the selective post-emergence control of wild oats, black-grass, and other annual grass weeds in winter wheat, barley, and rye.
• Broadleaf Crop Protection: Used in soybean, canola (rapeseed), sugar beet, and flax fields to manage competing grass weeds without harming the cash crop.
• Industrial & Non-Crop Areas: Applied in right-of-way management, industrial sites, and orchards for general vegetation control of grassy weeds.
• Manufacturing of Agrochemicals: Serves as the key technical-grade active ingredient (TC) for producing various commercial emulsifiable concentrate (EC) and wettable powder (WP) formulations.
• Research & Development: Utilized in agricultural research institutions for studying herbicide resistance, mode of action, and developing new synergistic mixtures.
