When an organosilicone surface active agent is added to a pesticidal aqueous suspension composition containing an active ingredient compound of a sparingly water-soluble pesticide for the purpose of attaining activity enhancement and formulation, the following problems arise: such that (1) the viscosity of the composition increases (2) a large amount of foams due to the organosilicone surface active agent tends to generate at the time of preparation of a spray solution and the like. Thus, measuring the composition and preparation of a spray solution were difficult. The present invention provides a pesticidal aqueous suspension composition including (a) an active ingredient compound of a sparingly water-soluble pesticide, (b) an organosilicone surface active agent, (c) a viscosity-reducing agent, (d) an antifoaming agent, (e) a pH adjustor and (f) a dispersant, which is suppressed in increasing in the viscosity, is easy to measure, hardly generates foams at the time of dilution with water and is easy to prepare a spray solution.當有機聚矽氧界面活性劑添加至含有微水溶性農藥之活性成分化合物之農藥水性懸浮劑組成物俾便用以達成活性提升及配方目的時,發生下列問題:(1)組成物黏度增高;(2)由於於噴霧劑溶液製備時,容易產生有機聚矽氧界面活性劑,故造成大量泡沫等問題。如此噴霧劑溶液之組成之測定與製備困難。本發明提供一種農藥水性懸浮劑組成物包括(a)微水溶性農藥之活性成分化合物,(b)有機聚矽氧界面活性劑,(c)減黏劑,(d)消泡劑,(e)pH調節劑,及(f)分散劑,該組成物可遏止黏度的增高,容易測量,以水稀釋時幾乎不會產生泡沫,且容易製備噴霧劑溶液。
