PROBLEM TO BE SOLVED: To obtain an antiseptic aqueous capsule suspension agrochemical preparation which has excellent handling and storage stability and shows high antiseptic property by including a specific amount of a nonionic water-soluble substance, which has a specific molecular weight and is solid at ordinary temperature, and water. SOLUTION: The objective preparation is obtained by mixing (A) a microcapsulized agrochemical active ingredient, (B) 3-30 wt.%, preferably 5-20 wt.%, of a nonionic water-soluble substance which has a molecular weight of 50-700 and is solid at ordinary temperature, (C) 30-90 wt.% of water and (D), when necessary, 0.1-10 wt.%, preferably 1-5 wt.%, of a disperser. As the ingredient B, succharides, e.g. monosacharides, oligosaccharides or the like, and water-soluble organic compounds, e.g. urea and the like, are illustrated. The average particle diameter of the microcapsule is preferably 0.1-200μm, more preferably 1-100μm. As the agrochemical active ingredient, insecticides, microbicides, herbicides, plant growth-controlling agents, insect growth- controlling agents, etc., are illustrated. The compound amount of the agrochemical active ingredient in the preparation is preferably 1-50 wt.%, more preferably 5-35 wt.%. |
