Abstract
A controlled release composition is prepared by contacting an organoclay with a biologically active material in concentrated form to cause absorption of the active material on the organoclay. The resulting product releases the active agent slowly, over a period of time, when exposed to the open atmosphere, for instance on being distributed over cultivated fields.
