    Abstract: PURPOSE: To obtain a pesticide granules emulsifiable in water that contains an agrochemically active substance insoluble or slightly soluble in water and a water-soluble shell-forming structure material, has no fluidity with reduced dusting, readily emulsifiable in water and can be added in a dose. CONSTITUTION: Pesticide granules, emulsifiable in water, comprises (A) at least 2-70wt.% of at least one selected from agrochemically active substances such as water-insoluble or slightly soluble herbicides, insecticides, fungicides, acaricides, nematocides, pheromones, repellents and the like and (B) 10-80wt.% of an at least partially water-soluble shell-forming structure material such as gelatin, gum Arabic, cellulose derivatives, starch derivatives, sodium alginate, PVA, poly(vinyl pyrrolidone). Said granules are produced by removing moisture from the aqueous dispersion of the components for the granules in a fluidized bed dryer that is operated by counter-currently. To these granules, when necessary, are formulated up to 80wt.% of a high-boiling solvent, up to 20wt.% of a moisturizer and up to 20wt.% of pharmaceutical additives.

    Abstract: PURPOSE: To obtain a suspoemulsion comprising phenoxaprop-p-ethyl, a herbicidal compound, a solvent and a surfactant composition. CONSTITUTION: This suspoemulsion comprises phenoxaprop-p-ethyl, a sulfonylurea-based and/or phenylurea-based herbicidal compound, an aromatic solvent or a solvent mixture and a surfactant composition o f ethoxylated tristyrylphenol and ethoxylated sterically modified synthetic alcohol having 13C average chain strength as active ingredients. The suspoemulsion comprises preferably 0.1-20wt.% phenoxaprop-p-ethyl, 0.1-60wt.% urea-based herbidical compound, 2-70wt.% solvent or solvent mixture and 0.1-30wt.% surfactant composition. The suspoemulsion is useful for removing growth of plants with are not desirable by applying the formulation to plants, plant seeds and culturing regions.
