<kr 2 61608 wherein X is chlorine or fluorine together with an inert carrier which is non-toxic to plants.

, 2-Ethanediylbis / carbamodithioato (2-) manganese is a known compound (see U.S. Patent Nos. 2,504,404 and 2,710,822), commonly known as "Maneb". The pyrimidine methanols of formula (I) are also known and can be prepared by the process described in GB Patent Publication No. 1,218,632. A compound of formula (I) wherein X is fluorine is preferred.

The novel composition of the present invention is surprisingly effective in the treatment and control of fungal infections in cereals. It is particularly effective as a seed dressing in the control of a number of important diseases, of which a representative sample is given below: 1. Barley diseases: (Hordeum vulgare)

Pyrenophora graminea Cohliobolus sativus Alonectria nivalis

Typhula incarnata Erysiphe graminis 2. Oat diseases: (Avena sativa)

Pyrenophora avenae 3. Wheat diseases Cercosporella herpotrichoides Tilletia spp.

Calonectria nivalis Leptoshaeria nodurum

Another aspect of the invention is thus the use of a composition according to the invention for the treatment of cereal seeds to control fungal diseases present in the seeds.

Although the new composition is preferably used as a seed dressing, advantageous results have also been obtained by applying a new combination to the leaves of the plant at any time from the appearance of the cob to the harvest; the frequency and duration of the treatment depend on the severity of the actual or expected disease. The ingredients of the combination can be applied sequentially or simultaneously to the cob to be treated.

Pyrimidinemethanol is preferably applied to the seeds in an amount of 0.05-0.8 g / kg, in particular 0.1 g / kg for wheat and 0.2 g / kg based on the seeds, and Maneb is again applied in an amount of 0 , 2-1.6 g / kg, especially about 0.8 g / kg based on seeds. The ratio of pyrimidinemethanol to Maneb is preferably 1: 2-1: 32, especially 1: 4-1: 8.

The novel combination according to the invention is preferably used as a fungicidal preparation containing pyrimidinemethanol and Maneb together with an inert carrier which is non-toxic to plants.

The fungicidal preparations according to the invention may contain from 5 to 90% by weight of active ingredients and are usually in the form of a wettable powder or dust.

Wettable powders or dusts consist of a thorough mixture of the active ingredients, one or more inert carriers and suitable surfactants. The inert strain may be selected from the group consisting of attapulgite clays, montmorillonite clays, diatomaceous earths, kaolins, mica, substances, talc and purified silicates. Effective surfactants can be found in the group consisting of sulfonated lignins, naphthalenesulfonates, alkylbenzenesulfonates and condensed naphthalenesulfonates, alkyl succinates, alkyl succinates, phenylene sulfonates such as alkyl benzene sulfonates, alkyl sulfates, alkyl sulfates. When used as a pickling agent, the preparations according to the invention also preferably contain a binder for attaching the preparation to the seeds, a pigment to indicate whether a certain batch of seeds has been treated or not, an insecticide and an avian repellent.

A representative example of wettable powders within the scope of the invention consists of the following composition:

Some non-limiting specific examples are provided below to further illustrate the invention. In these examples, CCPM means oC- (2-chlorophenyl) -10- (4-chlorophenyl) -5-pyrimidinemethanol and CFPM means oC- (2-chlorophenyl) -N- (4-fluorophenyl) -5-pyrimidinemethanol .

In Examples 1-3 above, the active ingredients are reduced to the appropriate size by conventional procedures and then mixed with the other ingredients in a conventional mixing apparatus. The mixture is ground. then in a liquid energy mill to a size of 1 to 10 micrometers, the mixture is then mixed again and deaerated before packaging.

In Examples 4 and 5, the active ingredients are reduced to the appropriate size by conventional procedures and then mixed with the other ingredients, whereby the oil or surfactant is sprayed onto the mixture. The mixture is then ground to a particle size of 5-50 micrometers. The mixture is mixed again and deaerated before packaging.

When the preparation of Example 1 was used as a seed dressing agent to control Septor (Leptospaeria nodorum) in wheat, a synergistic effect was obtained.
