PRODUCT INTRODUCTION
description
Dimethomorph is a mixture of (E)- and (Z)-dimethomorph in an unspecified ratio. It is used as a systemic fungicide used on vines, potatoes, and greenhouse crops; only the Z isomer has fungicidal activity. It has a role as a xenobiotic, an environmental contaminant and an antifungal agrochemical. It is a mixture and a morpholine fungicide. It contains an (E)-dimethomorph and a (Z)-dimethomorph.
