Herbicidal latex dispersion for controlled delivery and release of herbicides and their preparation

摘要

A controlled release and delivery system for a hydrophobic, water sensitive herbicide is produced by: (a) dissolving the herbicide in a volatile water-immiscible solvent; (b) introducing the solvent containing the herbicide dissolved therein to a latex dispersion comprising an aqueous continuous phase and polymeric discrete phase; (c) agitating the resultant mixture until the polymeric particles of the discrete phase absorb the herbicide; and (d) removing the solvent from the resultant mixture at reduced pressure.
