NOVELTY - Aqueous suspoemulsion (I) comprises a dispersed oil phase (a) comprising (i) a solvent having at least one triazole active compound dissolved in it; and a continuous water phase (b) comprising (ii) water having at least one strobilurin active compound suspended in it.    USE - (I) is useful for applying the agrochemically active compounds comprised in it to plants and/or their habitat to treat unwanted pests at a locus (all claimed). (I) is useful for controlling unwanted microorganisms such as fungi and bacteria, on a wide range of crops e.g. transgenic, crops of useful plants and ornamentals, e.g. cereals such as wheat, barley, rye, oats, sorghum and millet, rice, cassava and maize, or else crops of peanut, sugar beet, cotton, soya, oilseed rape, tomato, pea and vegetables. (I) (comprising tebuconazole (100 g/hectare) and trifloxistrobin (50 g/hectare)) was tested for its microbiocidal activity against soybean rust by measuring the severity grade determined according to the Diagrammatic Scale for Soybean Rust of EMBRAPA. The results showed that the severity percentage of rust, after 28 days of third application of (I), was 6.56% (for (I) treated soybeans) and 94.33% (for control treated soybeans).    ADVANTAGE - (I): is environmental friendly; has synergistic effect for controlling pests; and has potent microbiocidal activity. (I) is stable (i.e. no crystal growth is formed) even after prolonged storage at elevated temperatures or in the cold. (I) is highly suitable for applying the agrochemically active compounds comprised in it, to the plants. (I) does not exhibit side effects, upon dilution with water.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for the preparation of (I), comprising: (a1) preparing the triazole EC phase by mixing the active triazole ingredient with an alkyl carboxylic acid amide, which acts as a solvent and a crystal growth inhibitor, and a polymeric stabilizer; (a2) preparing a dispersion of particles of the strobilurin active ingredient in a continuous water phase by mixing the active ingredient, a dispersant and a required amount of water; and (a3) combining the oil phase produced in (a1) with the water phase produced in (a2).
