Description

Ioxynil-Methyl CAS NO 3336-40-1 is a selective post-emergence herbicide belonging to the hydroxybenzonitrile chemical class. This compound is valued for its potent systemic action, effectively controlling a range of broadleaf weeds in cereal crops. It is a critical agrochemical input for farmers and formulators seeking reliable weed management solutions. Its specific mode of action makes it a key component in integrated pest management programs.

Application

• Selective Herbicide in Cereals: Primary use for post-emergence control of broadleaf weeds, such as chickweed and mayweed, in wheat, barley, and rye.
• Agrochemical Formulations: Used as an active ingredient in the manufacture of emulsifiable concentrate (EC) and suspension concentrate (SC) herbicide formulations.
• Weed Resistance Management: Employed in rotation or tank-mix programs with herbicides of different modes of action to mitigate and manage weed resistance.
• Industrial Vegetation Control: Applicable for managing unwanted vegetation in non-crop areas like railways, roadways, and industrial sites.
• Research & Development: Serves as a reference standard and intermediate in agricultural chemical research for developing new crop protection agents.
