The components (C) are known. Where the components (C) are included in "The
Pesticide Manual" [The Pesticide Manual - A World Compendium; Thirteenth Edition; Editor: C. D. S. Tomlin; The British Crop Protection Council], they are in most cases described therein under the entry number given in round brackets hereinabove for the particular component (B); for example, the compound "abamectin" is described under entry number (1 ). Most of the components (C) are referred to hereinabove by a so- called "common name", the relevant "ISO common name" or another "common name" being used in individual cases. If the designation is not a "common name", the nature of the designation used instead is given in round brackets for the particular component (C); in that case, the IUPAC name, the lUPAC/Chemical Abstracts name, a "chemical name", a "traditional name", a "compound name" or a "development code" is used or, if neither one of those designations nor a "common name" is used, an "alternative name" is employed. Ametoctradin is being commercialised under the trade name Intium®. A synergistic effect exists whenever the action of an active ingredient combination is greater than the sum of the actions of the individual components. The action to be expected E for a given active ingredient combination obeys the so-called COLBY formula and can be calculated as follows (COLBY, S. R. "Calculating synergistic and antagonistic responses of herbicide combination". Weeds, Vol. 15, pages 20-22; 1967): ppm = milligrams of active ingredient (= a.i.) per liter of spray mixture X = % action by active ingredient A) using p ppm of active ingredient Y = % action by active ingredient B) using q ppm of active ingredient. According to COLBY, the expected (additive) action of active ingredients A)+B) using
X • Y p+q ppm of active ingredient is E = X + Y
100
If the action actually observed (O) is greater than the expected action (E), then the action of the combination is super-additive, i.e. there is a synergistic effect. In mathematical terms, synergism corresponds to a positive value for the difference of (O- E). In the case of purely complementary addition of activities (expected activity), said difference (O-E) is zero. A negative value of said difference (O-E) signals a loss of activity compared to the expected activity.
However, besides the actual synergistic action with respect to fungicidal activity, the mixtures and compositions according to the invention can also have further surprising advantageous properties. Examples of such advantageous properties that may be mentioned are: more advantageous degradability; improved toxicological and/or ecotoxicological behaviour; or improved characteristics of the useful plants including: emergence, crop yields, more developed root system, tillering increase, increase in plant height, bigger leaf blade, less dead basal leaves, stronger tillers, greener leaf colour, less fertilizers needed, less seeds needed, more productive tillers, earlier flowering, early grain maturity, less plant verse (lodging), increased shoot growth, improved plant vigor, and early germination.
Some mixtures and compositions according to the invention have a systemic action and can be used as foliar, soil and seed treatment fungicides.
With the mixtures and compositions according to the invention it is possible to inhibit or destroy the phytopathogenic microorganisms which occur in plants or in parts of plants (fruit, blossoms, leaves, stems, tubers, roots) in different useful plants, while at the same time the parts of plants which grow later are also protected from attack by phytopathogenic microorganisms.
The mixtures and compositions according to the invention can be applied to the phytopathogenic microorganisms, the useful plants, the locus thereof, and the propagation material thereof, storage goods or technical materials threatened by microorganism attack.
The mixtures and compositions according to the invention may be applied before or after infection of the useful plants, the propagation material thereof, storage goods or technical materials by the microorganisms.
The amount of a composition according to the invention to be applied, will depend on various factors, such as the compounds employed; the subject of the treatment, such as, for example plants, soil or seeds; the type of treatment, such as, for example spraying, dusting or seed dressing; the purpose of the treatment, such as, for example prophylactic or therapeutic; the type of fungi to be controlled or the application time.
When applied to the useful plants component (A) is typically applied at a rate of 5 to 2000 g a.i./ha, particularly 10 to 1000 g a.i./ha, e.g. 50, 75, 100 or 200 g a.i./ha, typically in association with 1 to 5000 g a.i./ha, particularly 2 to 2000 g a.i./ha, e.g. 100, 250, 500, 800, 1000, 1500 g a.i./ha of component (B).
In agricultural practice the application rates of the compositions according to the invention depend on the type of effect desired, and typically range from 20 to 4000 g of total composition per hectare.
When the mixtures and compositions according to the invention are used for treating seed, rates of 0.001 to 50 g of a compound of component (A) per kg of seed, preferably from 0.01 to 10g per kg of seed, and 0.001 to 50 g of a compound of component (B), per kg of seed, preferably from 0.01 to 10g per kg of seed, are generally sufficient.
The mixtures and composition of the invention may be employed in any conventional form, for example in the form of a twin pack, a powder for dry seed treatment (DS), an emulsion for seed treatment (ES), a flowable concentrate for seed treatment (FS), a solution for seed treatment (LS), a water dispersible powder for seed treatment (WS), a capsule suspension for seed treatment (CF), a gel for seed treatment (GF), an emulsion concentrate (EC), a suspension concentrate (SC), a suspo-emulsion (SE), a capsule suspension (CS), a water dispersible granule (WG), an emulsifiable granule (EG), an emulsion, water in oil (EO), an emulsion, oil in water (EW), a micro-emulsion (ME), an oil dispersion (OD), an oil miscible flowable (OF), an oil miscible liquid (OL), a soluble concentrate (SL), an ultra-low volume suspension (SU), an ultra-low volume liquid (UL), a technical concentrate (TK), a dispersible concentrate (DC), a wettable powder (WP) or any technically feasible formulation in combination with agriculturally acceptable adjuvants.
Such mixtures and compositions may be produced in conventional manner, e.g. by mixing the active ingredients with at least one appropriate inert formulation adjuvant (for example, diluents, solvents, fillers and optionally other formulating ingredients such as surfactants, biocides, anti-freeze, stickers, thickeners and compounds that provide adjuvancy effects). Also conventional slow release formulations may be employed where long lasting efficacy is intended. Particularly formulations to be applied in spraying forms, such as water dispersible concentrates (e.g. EC, SC, DC, OD, SE, EW, EO and the like), wettable powders and granules, may contain surfactants such as wetting and dispersing agents and other compounds that provide adjuvancy effects, e.g. the condensation product of formaldehyde with naphthalene sulphonate, an alkylarylsulphonate, a lignin sulphonate, a fatty alkyl sulphate, and ethoxylated alkylphenol and an ethoxylated fatty alcohol.
Customary formulation ingredients are, for example, formulation ingredients that are do not have any significant biological activity, or have no biological activity. They include, for example, diluents, solvents, fillers, surfactants, biocides, anti-freeze, stickers, thickeners and compounds that provide adjuvancy effects.
The compositions according to the invention may also comprise further pesticides, such as, for example, fungicides, insecticides or herbicides.
A seed dressing formulation is applied in a manner known per se to the seeds employing the compositions according to the invention and a diluent in suitable seed dressing formulation form, e.g. as an aqueous suspension or in a dry powder form having good adherence to the seeds. Such seed dressing formulations are known in the art. Seed dressing formulations may contain the single active ingredients or the combination of active ingredients in encapsulated form, e.g. as slow release capsules or microcapsules. In general, the formulations include from 0.01 to 90% by weight of active agent, from 0 to 20% agriculturally acceptable surfactant and 10 to 99.99% solid or liquid formulation inerts and adjuvant(s), the active agent consisting of at least a compound of component (A) together with a compound of component (B), and optionally other active agents, particularly microbiocides or conservatives or the like. Concentrated forms of compositions generally contain in between about 2 and 80%, preferably between about 5 and 70% by weight of active agent. Application forms of formulation may for example contain from 0.01 to 20% by weight, preferably from 0.01 to 5% by weight of active agent. Whereas commercial products will preferably be formulated as concentrates, the end user will normally employ diluted formulations.

28 parts of a combination of component (A) and component (B), or of each of these components separately, are mixed with 2 parts of an aromatic solvent and 7 parts of toluene diisocyanate/polymethylene-polyphenylisocyanate-mixture (8:1 ). This mixture is emulsified in a mixture of 1.2 parts of polyvinylalcohol, 0.05 parts of a defoamer and 51.6 parts of water until the desired particle size is achieved. To this emulsion a mixture of 2.8 parts 1 ,6-diaminohexane in 5.3 parts of water is added. The mixture is agitated until the polymerization reaction is completed. The obtained capsule suspension is stabilized by adding 0.25 parts of a thickener and 3 parts of a dispersing agent. The capsule suspension formulation contains 28% of the active ingredients. The medium capsule diameter is 8-15 microns. The resulting formulation is applied to seeds as an aqueous suspension in an apparatus suitable for that purpose.
Examples
Example 1 : Evaluation of different rates of Presidio® (fluopicolide), Revus® (mandipropamid) and Ridomil Gold SL® (metalaxyl-M) for control of downy mildew (B. lactucae) on lettuce
This study was conducted to determine the range of fungicide rates needed to allow for the detection of possible synergistic interactions between the products. Presidio was tested at 0.3, 1 and 3 mg a.i./L; Revus® was tested at 0.01 , 0.1 and 1 mg a.i./L; and Ridomil Gold SL® was tested at 0.3, 1 and 3 mg a.i./L. The rationale for selecting low rates of the fungicides was to have incomplete control of the disease and, therefore, be able to detect any synergistic interactions from mixtures. The disease severity levels with the fungicide concentrations selected were found to give appropriate levels of control and further studies were planned based on these concentrations, with the exception of the Revus® concentration of 1 mg a.i./L that provided too high a level of control of the disease (Table 1 ). Therefore, a lower concentration of Revus® (0.3 mg a.i./L) was selected for further studies. Table 1. Evaluation of different rates of Presidio®, Revus® and Ridomil Gold® on the reduction of down mildew caused b B. lactucae on lettuce.

Example 2: Evaluation of Mixtures of Presidio® and Revus® for control of downy mildew (B. lactucae) on lettuce
Presidio® at 0.3 and 1 mg a.i./L and Revus® at 0.1 and 0.3 mg a.i./L were tested alone and in combination for control of downy mildew caused by B. Lactucae. Plants were inoculated 24 h after the fungicide application with a sporangial suspension at a concentration of 1x104 sporangia/ml of water and spraying the inoculum on the lower and upper surfaces of leaves. At 8 days after inoculation disease severity was measured as % leaf area infected. Synergy between Presidio® and Revus® was not detected when Presidio® at 0.3 mg. a.i./L was combined with Revus® either at 0.1 or 0.3 mg a.i./L (Table 2). However, good synergistic interactions were detected when Presidio at a rate of 1 mg a.i./L was combined with Revus® at 0.1 or 0.3 mg a.i./L (Table 3).

Example 3: Evaluation of Mixtures of Presidio® and Revus® for control of downy mildew (B. lactucae) on lettuce - second study
A second study was conducted again looking at the synergistic interaction of Presidio® and Revus® on the control of lettuce downy mildew in order to validate the results obtained in the first study. As in the previous study, sporangia of B. Lactucae were inoculated one day after fungicide application. In this study, Presidio® was tested at 1 , 3 and 10 mg a.i./L and Revus® at 0.03, 0.1 and 0.3 mg a.i./L alone and in combination. The inoculum concentration was higher in this study, with 2x104 sporangia/ml inoculated on the lower and upper surfaces of the leaves. Eight days after inoculation, disease severity was measured as % leaf area infected. Disease severity was higher in this study compared to the previous one. The results of the first study were validated since good synergistic interactions between Presidio® and Revus® were detected in all combinations tested in the second study (Table 3).

Example 4: Evaluation of Mixtures of Presidio® and Ridomil Gold SL® for control of downy mildew (β. lactucae) on lettuce:
Presidio® at 0.3 and 1 mg a.i./L and Ridomil Gold SL® at 0.1 and 0.3 mg a.i./L were tested alone and in combination for control of lettuce downy mildew. Lettuce treated with fungicides or untreated were inoculated one day of application with a sporangial suspension adjusted to 1x104 sporangia/ml. Disease severity ratings were conducted 8 days after inoculation and measured as % leaf area infected. All the combinations of Presidio® and Ridomil Gold SL® exhibited clear synergistic interactions (Table 4).

In this second study, Presidio at 1 and 3 mg a.i./L and Ridomil at 0.3, 1 and 3 mg a.i./L were tested alone and in combination for control of lettuce downy mildew. Lettuce treated with fungicides or untreated were inoculated one day of application with a sporangial suspension adjusted to 2x104 sporangia/ml. The inoculum concentration was higher in this study compared to the first one. Disease severity ratings were conducted 8 days after inoculation and measured as % leaf area infected. Once again, all the combinations of Presidio and Ridomil Gold SL exhibited clear synergistic interactions (Table 5).
