Abstract

The fungicidal composition consists of a mixture of a triazole or pyrimidine compound with a benzimidazole compound or an aluminium salt of ethyl phosphite, optionally mixed with carriers, diluents or excipients. The compounds are suitable for the curative or preventive fungicidal treatment of vine downy mildew or cereal powdery mildew.

Description

The invention relates to a fungicidal composition.

The fungicidal composition according to the invention is characterized in that it contains as a fungicidally active ingredient a pyrimidine compound of the formula I

A preferred pyrimidine of the formula I for the desert treatment of grapes is one where X is a chlorine atom, while a compound of the formula I where X is a fluorine atom is preferred for use in conjunction with fungal infections of 10-10.

The components of the composition according to the invention can be applied to the plant to be treated sequentially or simultaneously, the latter method being pre-treated. The compounds of the formula I are preferably applied in an amount of 10 to 100 g, most preferably from 10 to 30 g per hectare in the treatment of grapes, while the compounds of the formula II are preferably applied in an amount of 100 to 3000 g per hectare. . Thus, the ratio of the compounds of formula I to the compounds of formula II in the combinations according to the invention may range from 1:10 to 1: 100, expressed as

The compound of formula (II), the aluminum salt of dimethyl (AEEP), is preferably used in combination with another fungicide, for example mancose or optionally with folpet, 2- (chloromethyl) -. -thioi “^! H-isoiodol-1,3 (2H) -dione. / viz. Yt ^ ί ^^ Phytopharmoaie. /.197,7/.7.

In order to simplify production, storage and transport, a combination of compounds of formula I and compounds of formula I is used.

Such concentrate compositions may contain 0.5 to 90 Z, preferably 5. to. 90 Of the active ingredients, supplemented with one or more inert non-phytotoxic agents. such compositions will generally be in the form of a dry powder, dust or aqueous suspension, although aqueous AEP suspensions. has a tendency to instability due to the relatively short half-life.
