Microcapsules of Clomazone are described, for their use in tailored release of chemicals. The described process is a novel microencapsulation method using certain acetylene carbamide derivatives that reduces the toxicity associated with some previously described processes of microencapsulation using higher quantities of isocyanates of the type toluene diisocyanate.
