ABSTRACT:
A biocidal powder having a notably reinforced biological effect contains at least 50 wt % of particles having diameter of 0.5 micron or less.
A suspension containing the above powder is prepared by mixing a dispersion liquid which comprises a biocidal substance and a specified dispersing agent such as a polymer of styrene sulfonate with rigid media having particle diameter of 0.5 mm or less.
Thus obtained suspension is applicable to germicides, herbicides, insecticides, miticides and the like.
