Definitions

• the present invention relates to fungicidal mixtures comprising

They are partly systemically effective and can therefore also be used as leaf and soil fungicides.
• the compounds I and II can be applied simultaneously, that is jointly or separately, or in succession, the sequence in the case of separate application generally not having any effect on the success of the control measures.

• the form of application depends on the intended use; in any case, it should ensure that the mixture according to the invention is as fine and uniform as possible.
• the formulations are prepared in a manner known per se, e.g. by adding solvents and / or carriers. Inert additives such as emulsifiers or dispersants are usually added to the formulations.
• alkali, alkaline earth, ammonium salts of aromatic sulfonic acids e.g. Lignin-,
• Powders, materials for broadcasting and dusts can be prepared by mixing or jointly grinding the compounds I or II or the mixture of the compounds I and II with a solid carrier.

• the infection of the treated plants corresponds to that of the untreated control plants; at an efficiency of 100, the treated plants showed no infection.
• the expected efficacies of the active ingredient mixtures were determined using the Colby formula [RS Colby, Weeds 15, 20-22 (1967)] and compared with the observed efficiencies.
• Leaves of potted plants of the "large meat tomato St. Pierre" were sprayed to runoff point with an aqueous suspension which was prepared from a stock solution consisting of 10% active ingredient, 85% cyclohexanone and 5% emulsifier. The following day, the leaves were infected with a cold aqueous zoo spore suspension of Phytophthora infestans with a density of 0.25 x 10 6 spores / ml. The plants were then placed in a steam-saturated chamber at temperatures between 18 and 20 ° C. After 6 days, the blight on the untreated but infected control plants had developed so strongly that the infestation could be determined visually in%.
