Uses

Agricultural fungicide.

Definition

ChEBI: 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.

Agricultural Uses

Fungicide: A systemic fungicide that protects crops from mold. It also kills mold and prevents their spread; controls late blight on tomatoes; and is used as a wood preservative to control downey mildew.

Metabolic pathway

Limited data are available in the open literature. Information presented in this summary is abstracted from the data evaluation published by the Pesticide Safety Directorate (PSD, 1994). Dimethomorph is a (1:l) mixture of the E- and Z-isomers. The Z-isomer has been shown to have all the intrinsic biological activities. The isomerisation of the E- and Z-isomers was observed when resolved isomers were exposed to UV light. Dimethomorph undergoes extensive degradation and metabolism in soil, plants and animals. The major metabolic pathway is the O-demethylation of one of the phenolic methoxy moieties to the corresponding phenols and conjugates. Other metabolic reactions include the oxidation of one of the CH2 moieties of the morpholine ring and the cleavage/opening of the morpholine ring (Scheme 1).

Degradation

Dimethomorph (1) is hydrolytically stable with no observable degradation in pH 4-9 buffered solutions at 70-90 °C for up to 10 weeks.
Degradation occurred when dimethomorph in pH 5 buffer solution was irradiated under Hanau Suntest apparatus (<290 nm) at 25 °C. The calculated aqueous photolytic degradation half-life (DT₅₀) was ca. 25-28 days of continuous irradiation, No sigruficant degradation product (>7% of the applied radioactivity) was identified.
