Description

Difenzoquat Methylsulfate is a quaternary ammonium salt widely recognized for its potent herbicidal activity. This compound matters for its selective action against specific weed species, making it a valuable tool in integrated crop management systems. It is primarily needed by the agrochemical industry for the formulation of post-emergence herbicides targeting wild oats and other grassy weeds in cereal crops like wheat and barley.

Application

• Primary use as a selective post-emergence herbicide for broad-acre farming.
• Formulation of commercial agrochemical products for control of wild oats (Avena fatua) in wheat, barley, and rye.
• Management of other annual grassy weeds in cereal crop production systems.
• Used in research and development as a standard or reference compound for herbicidal efficacy studies.
• Potential application in non-crop areas for vegetation control, subject to local regulatory approval.
• Investigated for use in seed treatment protocols to protect crop yield.
