    • The present invention provides a wettable composition for use in agriculture comprising microorganisms as an active ingredient, which can maintain a high survival rate of the same over long periods, and exhibit superior physical properties during applications, and provide a method for stably storing the wettable composition for use in agriculture for a long period of time. That is, the present invention corresponds to a wettable composition for use in agriculture comprising spores of filamentous fungi which are in the form of dried powders having a volume median diameter ranging from 2 &mgr;m to 10 &mgr;m, and having a ratio of (volume 90% diameter)/(volume 10% diameter;) of not more than 5.62, and an adsorbent having a water absorption ability in an amount of at least 1% by mass based on the total mass of the composition. The composition is prepared by pulverizing and mixing a mixture of spores of filamentous fungi, an adsorbent having a water absorption ability, and other additive components such as a surfactant, in an appropriate ratio of the same, by means of impact pulverization, and adjusting a moisture content so that the moisture content is less than 2.5% by mass based on the total mass of the composition. In addition, the composition is stored by packaging in a bag formed from a hermetic film.
    • 本发明提供了一种用于农业的可湿性组合物,其包含微生物作为活性成分,其可长期保持其高存活率,并且在使用期间表现出优异的物理性能,并提供稳定地储存可湿性组合物的方法 长期用于农业。 也就是说,本发明对应于一种用于农业的可湿性组合物,其包含丝状真菌的孢子,其为体积中值粒径为2μm至10μm的干燥粉末形式,并且具有(体积90% 直径)/(体积10%直径)为5.62以下,吸水能力为相对于组合物总质量至少1质量%的吸附剂。 组合物通过粉碎和混合丝状真菌的孢子,具有吸水能力的吸附剂和其它添加剂组分如表面活性剂的混合物,通过冲击粉碎以适当的比例粉碎和混合,并调节 水分含量使得水分含量基于组合物的总质量小于2.5质量%。 此外,组合物通过包装储存在由密封膜形成的袋中。
