DETAILED DESCRIPTION OF THE INVENTION The present invention provides (E)-/-(,2,Q-dichlorophenyl)-g, goo-dimethyl-J-(/, ,2. &-tri7zol-/-yl)-/-pentene. -3-ol (
A bactericidal composition (hereinafter referred to as compound (A)) and N-(dichlorofluoromethylthio)-N',N'-dimethyl-N-phenyl sulfate 7mide (generic name: dichlorofluanid) as active ingredients. 0) referred to as the composition of the present invention.

Dichlorofluanid, which is one of the active ingredients of the composition of the present invention, is effective in controlling plant diseases of vegetables, fruit trees, and flower petals.
It has extremely low toxicity to humans and animals, is effective against a wide range of plant diseases, and is in practical use.

However, although dichlofluanid is highly effective against gray mold, apple leaf spot, downy mildew, late blight, etc., it is not sufficiently effective against powdery mildew, rust, etc. (Fukunaga-huo ed.,
Pesticide Handbook, Japan Plant Protection Association, /976) On the other hand, compound [A] (% Kaishoj j-/2 Schiff No. 7/ Publication) is resistant to diseases of divine patterned plants such as grains, fruit trees, and vegetables. It is known that dichlofluanid and compound (A) have preventive and curative effects, but are dichlofluanid and compound (A) effective against plant diseases? 1 range is different. The present invention provides that the composition of the present invention enables the control of a wide range of plant diseases;
