Abstract: A microcapsule can be produced easily by (a) pulverizing a solid pesticidal compound in a fatty acid ester represented by formula (I) to form a suspension wherein X denotes either —CH2—CH2— or —CH?CH— and R1 and R2 each denote a C1-C4 alkyl group, (b) mixing the resulting suspension and water to prepare a liquid droplet, and (c) forming a coating film around the liquid droplet. A microcapsule obtained in such a way contains most of the solid pesticidal compound within the microcapsule.

Abstract: A pesticidal composition comprising 4-phenoxyphenyl 2-(2-pyridyloxy)propyl ether; a hydrophobic organic solvent capable of dissolving 0.1-fold by weight of 4-phenoxyphenyl 2-(2-pyridyloxy)propyl ether at 0° C.; polyvinyl alcohol; a nonionic surfactant selected from the group consisting of alkoxylated castor oil, alkoxylated hydrogenated castor oil and alkoxylated hydrogenated castor oil fatty acid ester; and water, is excellent in storage stability.

Abstract: A microcapsule can be produced readily by (a) pulverizing a solid pesticidal compound in terpineol, dihydroterpineol, terpinel acetate, dihydroterpinel acetate or a mixture thereof to form a suspension, (b) mixing the resulting suspension and water to prepare a liquid droplet, and (c) forming a coating film of a resin around the liquid droplet. The microcapsule obtained by such a method contains most of the solid pesticidal compound within the microcapsule.

Abstract: A herbicidal composition which comprises a protoporphyrinogen oxidase inhibiting herbicidal active ingredient, a water-soluble herbicidal active ingredient, a water-soluble anionic surfactant, a polyoxyalkylenehydrocarbylamine, a water-immiscible organic solvent in which the protoporphyrinogen oxidase inhibiting herbicidal active ingredient cannot be substantially dissolved, a thickner and water, wherein the protoporphyrinogen oxidase inhibiting herbicidal active ingredient is suspended in the water dissolving the water-soluble herbicidal active ingredient as solid fine particles has excellent suspension stability.

Abstract: A microcapsule can be produced easily by (a) pulverizing a solid pesticidal compound in a fatty acid ester represented by formula (I) to form a suspension wherein X denotes either —CH2—CH2— or —CH=CH— and R1 and R2 each denote a C1-C4 alkyl group, (b) mixing the resulting suspension and water to prepare a liquid droplet, and (c) forming a coating film around the liquid droplet. A microcapsule obtained in such a way contains most of the solid pesticidal compound within the microcapsule.

Abstract: A method for producing a human lymphocyte producing an antibody specific to a desired antigen, a method for producing a monoclonal antibody, as well as monoclonal antibodies produced by the method, are described. The present invention provides a method for producing a human lymphocyte producing an antibody comprising, in the order mentioned, the steps of: transplanting human lymphocytes into an immunodeficient animal so that the human lymphocytes take in the animal body; immunizing the animal with a desired antigen so as to generate human lymphocytes producing an antibody specific to the antigen; and recovering the human lymphocytes producing the antibody from the animal.
