Application
Dimethomorph is a systemic
fungicide which protects plants from molds, as well as killing molds
on plants and preventing their spread. It is a cinnamic acid
derivative and a member of the morpholine chemical family.
Dimethomorph is a systemic morpholine fungicide for use on potatoes.
Its mode of action is the inhibition of sterol (ergosterol)
synthesis. Morpholines are all systemic with curative and
preventative qualities. Dimethomorph was developed for downy
mildews, late blights, crown and root rots for grapes, potatoes,
tomatoes, and other vegetables.. Dimethomorph is used as a wood
preservative to control downy mildew on vines, and to control late
blight on tomatoes and potatoes.
