Product information

Crops: Cucumber, Vine, Potato, etc.

Diseases: Active against Oomycetes fungi, especially Peronosporaceae and Phytophthora, etc.

Mode of action: Local systemic fungicide with good protectant and antisporulant activity. Only the (Z)- isomer is intrinsically active, but, because of rapid interconversion of isomers in the light, it has no advantage over the (E)- isomer in practice.

Usage: Fungicide effective against Oomycetes, especially Peronosporaceae and Phytophthora spp. (but not Pythium spp.) in vines, potatoes, tomatoes and other crops. Used in combination with contact fungicides, and applied at 2.0–2.5 kg formulated product/ha.

Formulations: Dimethomorph 50%WP; (9%Dimethomorph+60%Mancozeb)WP
