It is an object of the present invention to provide fungicidal mixtures having good fungicidal activity, in particular against fungal diseases in rice, exceeding the activity of the mixture components on their own.

We have found that this object is achieved by the mixtures as claimed in claim 1.

The compounds of the formula I are known per se and are described in the literature (WO 97/15552).

The fungicides of the formulae II to VII are also known and described in the literature. Additionally, they are commercially 0050/48894 6 available under the trade names mentioned below in brackets: II: GB 1,394,373; common name: pyroquilon (trade name: Coratop®, from Novartis); III:GB 1,419,121, common name: tricyclazole (trade name Beam®, from Dow Elanco); IV: Proc. Insect. Fungic. Conf. 8th, 2 (1975), 715, common name: isoprothiolane (trade name: Fuji-one®, from Nihon Noyaku); V: DE 14 93 736, common name: edifenphos (trade name: Hinosan®, from Bayer); VI: GB-A 1,312,536, US-A 3,755,350; common name: ferimzone (from Takeda); 2VII:Pesticide Manual 10th Ed., 1994, 482; common name: fludioxinil (trade name: Celest®,from Novartis).

Owing to their C=C and C=N double bonds, the preparation of the compounds I may yield E/Z isomer mixtures which can be separated into the individual compounds in a customary manner, for example by crystallization or chromatography.

However, if the synthesis yields isomer mixtures, a separation is generally not necessarily required since in some cases the individual isomers can be converted into one another during the preparation for use or upon use (for example under the action of light, acids or bases). Corresponding conversions may also occur after the use, for example in the treatment of plants in the treated plant or in the harmful fungus or animal pest to be controlled.

With regard to the C=X double bond, preference is given to the E isomers of the compounds I (configuration based on the -OCH 3 or the -CH 3 group in relation to the -C0 2

R

1 group) with respect to 4their activity.

With regard to the -C(R 3

)=NOCH

2 double bond, preference is given to the cis isomers of the compounds I (configuration based on the 4radical R 3 in relation to the -OCH 2 group) with respect to their t activity.

Evaluation is carried out by determining the infected leaf areas in percent. These percentages are converted into efficacies. The efficacy is calculated as follows using Abbot's formula: W (1 a).100/p a corresponds to the fungal infection of the treated plants in and f corresponds to the fungal infection of the untreated (control) plants in An efficacy of 0 means that the infection level of the treated plants corresponds to that of the untreated control plants; an efficacy of 100 means that the treated plants were not infected.

The expected efficacies of the mixtures of the active ingredients were determined using Colby's formula Colby, Weeds 20-22 (1967)] and compared with the observed efficacies.

Colby's formula: E x y x-y/100 E is expected efficacy, expressed in of the untreated control, when using the mixture of the active ingredients A and B at the concentrations a and b x is the efficacy, expressed in of the untreated control, when using active ingredient A at the concentration a y is the efficacy, expressed in of the untreated control, when using active ingredient B at the concentration b Use Example 1 Activity against Pyricularia oryzae (protective) Leaves of potted rice seedlings c.v. "Tai-Nong 67" were sprayed to runoff point with an aqueous preparation of active ingredient which had been prepared from a stock solution comprising 10% of active ingredient, 63% of cyclohexanone and 27% of emulsifier.

The following day, the plants were innoculated with an aqueous spore suspension of Pyricularia oryzae. The test plants were subsequently placed in climatized chambers at 22-24 0 C and 95-99% re- A <_tive atmospheric humidity for 6 days. The extent of the deve- 0050/48894 lopment of the disease on the leaves was then determined visually.

The visually determined values for the percentage of diseased leaf area were converted into efficacies as percent of the untreated control. An efficacy of 0 means the same disease level as in the untreated control, an efficacy of 100 means 0% disease.

The expected efficacies for active ingredient combinations were determined using Colby's formula (Colby, S. "Calculating synergistic and antagonistic responses of herbicide combinations", Weeds 15, pp. 20-22, 1967) and compared with the observed efficacies.

As component use was made of the following compound I':
