The object of the present invention was to provide further means for combating harmful fungi and in particular for certain indications.

Surprisingly, it has now been found that this object is achieved with a mixture which comprises benzamide oxime derivatives of the formula I defined at the beginning and, as a further fungicidally active component, a fungicidal active substance from the class of azoles II to XXIII.

The mixtures according to the invention act synergistically and are therefore particularly suitable for controlling harmful fungi and in particular powdery mildew in cereals, vegetables and vines.

In the context of the present invention, halogen represents fluorine, chlorine, bromine and iodine and in particular fluorine, chlorine and bromine.

The term "alkyl" encompasses straight-chain and branched alkyl groups. These are preferably straight-chain or branched C 1 -C ₄ -alkyl groups. Examples of alkyl groups are alkyl, in particular methyl, ethyl, propyl, 1-methylethyl, butyl, 1-methylpropyl, 2-methylpropyl and 1, 1-dimethylethyl. Haloalkyl stands for an alkyl group as defined above which is partially or completely halogenated with one or more halogen atoms, in particular fluorine and chlorine. There are preferably 1 to 3 halogen atoms, with the difluoromethane / - or the trifluoromethyl group being particularly preferred.

The above statements on the alkyl group and haloalkyl group apply correspondingly to the alkyl and haloalkyl groups in alkoxy and haloalkoxy.

The radical R in the formula I preferably represents a hydrogen atom.

Examples of compounds of the formula I are listed in Table 1.

Table 1

The mixtures according to the invention contain at least one compound of the formula II to XXIII as the azole derivative.

In order to develop the synergistic effect, a small proportion of benzamide oxime derivative of the formula I is sufficient. Benzamide oxime derivative and azole are preferably used in a weight ratio in the range from 20: 1 to 1:20, in particular 10: 1 to 1 : 10 used. Because of the basic character of the nitrogen atoms contained in them, the azoles II-XXIII are able to form salts or adducts with inorganic or organic acids or with metal ions.

Examples of inorganic acids are hydrohalic acids such as hydrogen fluoride, hydrogen chloride, hydrogen bromide and hydrogen iodide, sulfuric acid, phosphoric acid and nitric acid.

Examples of organic acids are formic acid, carbonic acid and alkanoic acids such as acetic acid, trifluoroacetic acid, trichloroacetic acid and propionic acid as well as glycolic acid, thiocyanic acid, lactic acid, succinic acid, citric acid, benzoic acid, cinnamic acid, oxalic acid, alkylsulfonic acids (sulfonic acids with straight-chain alkyl radicals) 20 carbon atoms), arylsulfonic acids or disulfonic acids (aromatic radicals such as phenyl and naphthyl which carry one or two sulfonic acid groups), alkylphosphonic acids (phosphonic acids with straight-chain or branched alkyl radicals having 1 to 20 carbon atoms), arylphosphonic acids or diphosphonic acids (aromatic radicals such as phenyl and naphthyl which carry one or two phosphoric acid residues), where the Al yl or aryl residues can carry further substituents, for example p-toluenesulfonic acid, salicylic acid, p-amino salicylic acid, 2-phenoxybenzoic acid, 2-acetoxybenzoic acid etc.

In particular, the ions of the elements of the first to eighth subgroups, especially chromium, manganese, iron, cobalt, nickel, copper, zinc and, in addition, of the second main group, especially calcium and magnesium, of the third and fourth main group come as metal ions Aluminum, tin and lead are considered. The metals can, if appropriate, be present in various valencies to which they are assigned.

XXIII 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 application rates of the mixtures according to the invention, especially for agricultural crop areas, are from 0.01 to 8 kg / ha, preferably 0.1 to 5 kg / ha, in particular 0.5 to 3.0 kg / ha, depending on the type of effect desired ,

The application rates for the compounds I are 0.01 to 2.5 kg / ha, preferably 0.05 to 2.5 kg / ha, in particular 0.1 to 1.0 kg / ha.

The application rates for the compounds II to XXIII are accordingly from 0.01 to 10 kg / ha, preferably 0.05 to 5 kg / ha, in particular 0.05 to 2.0 kg / ha.

In the case of seed treatment, application rates of mixture of 0.001 to 250 g / kg of seed, preferably 0.01 to 100 g / kg, in particular 0.01 to 50 g / kg, are generally used.

If pathogenic fungi are to be combated for plants, the separate or joint application of the compounds I and at least one of the compounds II to XXIII or their mixtures of the compounds I and at least one of the compounds II to XXIII is carried out by spraying or dusting the seeds, the plants or the soil before or after sowing the plants or before or after emergence of the plants.

example

The synergistic effect of the mixtures according to the invention can be demonstrated by the following experiments:

The active ingredients are prepared separately or together as a 10% emulsion in a mixture of 63% by weight cyclohexanone and 27% by weight emulsifier and diluted with water in accordance with the desired concentration.

The evaluation is carried out by determining the affected leaf areas in percent. These percentages are converted into efficiencies. The efficiency (W) is determined according to Abbot's formula as follows: α

W = (1 - -) # ιoo ß

α ^• corresponds to the fungal attack of the treated plants in% and ß corresponds to the fungal infection of the untreated (control) plants in%

With an efficiency of 0, 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 calculated using the Colby formula [R.S. Colby, Weeds 15, 20-22 (1967)] and compared with the observed efficiencies.

Example of use 1: Activity against powdery mildew caused by Erysiphe [syn. Blumeria.] Graminis forma specialis. tri tici

Leaves of potted wheat seedlings of the "Kanzler" variety were sprayed to runoff point with aqueous preparation of active compound, which was prepared from a stock solution consisting of 10% active compound, 85% cyclohexanone and 5% emulsifier, and 24 hours after the spray coating had dried on, with spores wheat powdery mildew {Erysiphe [syn. Blumeria] graminis forma specialis. tri tici) pollinated. The test plants were then placed in a greenhouse at temperatures between 20 and 24 ° C and 60 to 90% relative humidity. After 7 days, the extent of mildew development was determined visually in% infestation of the entire leaf area.

The visually determined values for the percentage of leaf areas affected were converted into efficiencies as% of the untreated control. Efficiency 0 is the same as in the untreated control, efficiency 100 is 0%. The expected efficacies for combinations of active ingredients were determined using the Colby formula (Colby, SR (Calculating synergistic and antagonistic responses of herbicide combinations ", Weeds, 15, pp. 20-22, 1967) and compared with the observed efficacies.

The results of the experiment show that the observed efficiency in all mixing ratios is higher than the efficiency calculated in advance by the Colby formula (from Synerg 174. XLS).

Example of use 2: Curative activity against wheat brown rust caused by Puccinia recondi ta

Leaves of "Kanzler" wheat seedlings grown in pots were dusted with spores of the brown rust (Puccinia recondi ta). The pots were then placed in a chamber with high air humidity (90 to 95%) and 20 to 22 ° C. for 24 hours. During this time, the spores germinated and the germ tubes penetrated the leaf tissue. The next day, the infected plants were sprayed to runoff point with an aqueous active compound preparation which was prepared from a stock solution consisting of 10% active compound, 85% cyclohexanone and 5% emulsifier. After the spray coating had dried on, the test plants were cultivated in a greenhouse at temperatures between 20 and 22 ° C. and 65 to 70% relative atmospheric humidity for 7 days. The extent of the rust fungus development on the leaves was then determined.

The visually determined values for the percentage of leaf areas affected were converted into efficiencies as% of the untreated control. Efficiency 0 is the same as in the untreated control, efficiency 100 is 0%. The expected efficacies for combinations of active substances were determined using the Colby formula (Colby, S.R. (Calculating synergistic and antagonistic responses of herbicide combinations ", Weeds, 15, pp. 20-22, 1967) and compared with the observed efficacies.
