General description

Diclofop-methyl is an early post-emergence phenoxypropanoic acid herbicide. Its mode of action involves inhibition of acetyl CoA carboxylase (ACCase) activity, which in turn decreases fatty acid synthesis in weeds and inhibits photosynthesis and the activity of meristem.

Application

Diclofop-methyl may be used as a reference standard for the determination of diclofop-methyl in soil samples by gas-liquid chromatography (GLC).
Refer to the product′s Certificate of Analysis for more information on a suitable instrument technique. Contact Technical Service for further support.
