Abstract
The invention provides an insecticidal composition comprising Diazinon ensulated in microcapsules, the microcapsules having an encapsulating wall formed essentially from the reaction product of toluene diisocyanate and a polyfunctional amine, and further provides a process for encapsulating Diazinon in a microcapsular formulation comprising providing an aqueous phase containing a non-basic emulsifier, providing an organic phase containing toluene diisocyanate and Diazinon, combining the aqueous and organic phase to form an oil in water emulsion, and adding an aqueous solution of a polyfunctional amine with agitation to the emulsion, whereby the amine reacts with the toluene diisocyanate to form microcapsular envelopes about the Diazinon material.
