Outline of method
Dimethomorph is dissolved in acetonitrile and determined by high performance liquid chromatography on a reversed phase column (RP18) with acetonitrile + water (45 + 55 v/v) eluent and UV detection at 243 nm. The content of active ingredient is calculated from peak areas using an external standard.
The method is usable for TC, WP, WG and DC formulations.
