Abstract: A readily, water-dispersible pesticide formulation in the form of a thick paste containing 1 to 80% by weight of the pesticide, 0.30 to 2.0% by weight of a micropore-generating agent and 30 to 50% by weight of effervescent agents the percentages being based on the total weight of the formulation.

Abstract: Granules prepared by absorbing on hydrophilic polymer granules an aqueous emulsion of at least one active principle and drying the resulting mixture to obtain granules which release the active principle in uniform manner.

Abstract: Granules prepared by absorbing on hydrophilic polymer of acrylic acid polymers and/or acrylamide polymers granules an aqueous emulsion of at least one active principle such as pyrethrinoids and drying the resulting mixture to obtain granules which release the active principle in uniform manner.

Abstract: A process for the preparation of stable suspensions and powders of stable microcapsules containing at least one active material having a variable porosity comprising preparing a colloidal solution of equal parts by weight of gelatin and acacia gum with a total concentration of 4 to 6% by weight of the final emulsion, preparing an oil solution, suspension or emulsion of the active material at a concentration of 1 to 5% by weight of the final emulsion and containing a variable amount of organosoluble ethyl hydroxyethylcellulose, mixing the said two compositions with stirring at a temperature near 50.degree. C. in the presence of an emulsifying agent to form an "oil in water" emulsion, effecting consecutively coacervation and microencapsulation of the emulsified droplets containing the active material by adjusting the pH to 4.2 to 4.4 by addition of an acid and then cooling the mixture to about 20.degree.
