Abstract:
    A granule-shaped composition containing an agricultural chemical compound and a high proportion of an anionic surface-active agent of selected types in an effective amount to enhance the useful biological activity of said agricultural chemical compound may readily be produced by a process wherein a concentrated aqueous solution or slurry containing said agricultural chemical compound and the anionic surface-active agent at selected ratios, as well as one or more optional additives such as a solid vehicle or water-soluble extender is atomized by means of a spray nozzle of specified outlet orifice diameter and is spray-dried in a spray-drying tower chamber according to a counter-current flow spray-drying method in a specially stipulated manner and under specially selected conditions of operation. The granule-shaped composition so produced has a substantially hollow space within each substantially spherical granule and shows high free-flowing property, favorable collapsibility or disintegrability into water, and favorable solubility or dispersibility in water.
