Claims (8)

1. A microencapsulated formulation consisting of A) a particle dispersion phase of a) the reaction product of - at least one diamine, polyamine, dialcohol, polyalcohol and/or aminoalcohol with - a isocyanate mixture obtained during the dimerization and/or trimerization of hexamethylene-1,6-diisocyanate of the formulation OCN-(CH2)6-NCO (I) and/or during the reaction of hexamethylene-1,6-diisocyanate of the formulation (I) with water and/or carbon dioxide, if appropriate in the mixture with toluileine diisocyanate b) containing at least one fungicide active compound from the amino derivatives or morpholine derivatives. or azole derivatives and/or at least one insecticidal active compound from the phosphoric ester, pyrethroid, or carbamate group and/or at least one weedkilling active compound from the acetanilide group; and c) if appropriate, additives, dispersed phase particles with an average particle size between 1 and 20 μm; and B) liquid aqueous phase. 2. The microencapsulated formulation as per claim 1 is characterized by the encapsulated fungicide active compound being spirosamine. 3. The microencapsulated formulation as per claim 1 is characterized by the presence of the active fungicide compound, fenpropidim. 4. The microencapsulated formulation as per claim 1 is characterized by the presence of the active insecticidal compound, phenamiphos. 5. The microencapsulated formulation as per claim 1 is characterized by the presence of the active insecticidal compound, tebupyrimphos. 6. The microencapsulated formulation as per claim 1 is characterized by the presence of the active insecticidal compound, cyfluthrin. 7. The formulation of the microencapsulated formulation according to Patent 1, characteristic name, which contains the insecticidal active compound beta-cyfluthrin. 8. The procedure for the preparation of the microencapsulated formulation according to Patent 1, characteristic name, which, alpha) in step one, contains at least one fungicidal active compound from the amino derivative, morpholine derivative or azole derivative group and/or at least one insecticidal active compound from the phosphoric ester, pyrethroid or carbamate group and/or at least one herbicide active compound from the acetanyl group - mixed with an isocyanate mixture obtained during the dimerization and/or trimerization of hexamethylene-1,6-diisocyanate of formulation OCN-(CH2)6-NCO (I) and/or during the reaction of hexamethylene-1,6-diisocyanate of formulation (I) with water and/or carbon dioxide. If appropriate, mix with toluene diisocyanate, and if appropriate, with organic solvents, and if appropriate, with an emulsifier (beta). Then, in the second step, disperse the final mixture in water. If appropriate, as a mixture with additives (and gamma). In the third step, add at least one diamine, polyamine, dialcohol, polyalcohol, and/or aminoalcohol, if appropriate, as a mixture with water, and then, if appropriate, add more additives to the final dispersion. 8. The use of the microencapsulated formulations as per claim 1 for the application of the encapsulated agrochemical active compounds to the plant and/or the plant's environment.
