<p>Disclosed is a continuous process for the production of methomyl comprising the steps of: continuously forming, in an inert organic solvent and at an elevated reaction-initiating temperature of from about 30-70.degree.C, a liquid mixture of methylthloacetaldoxime and with methyl isocyanate in an amount in excess of stoichiometric proportions ; passing the mixture through a plug-flow, adiabatic, tubular reactor, maintained at a pressure of from about 30 to 70 psig, to produce reaction product at a temperature up to a reactor discharge temperature of from about 80 to 120.degree.C; and withdrawing the reaction product from the reactor and stripping unreacted methyl isocyanate and solvent therefrom to provide product methomyl, while recycling at least a portion of the unreacted isocyanate and solvent to the mixture.
