  • Wettable compositions for use in agriculture, preparation method therefor, and storage method therefor
    Patent number: 6750176
    Abstract: 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.
    Type: Grant
