ABSTRACT:
An herbicidal composition containing from 1 to 4 pounds of clomazone per gallon of formulation and having a clomazone volatility less than fifty percent of that of an emulsifiable concentrate containing four pounds of clomazone per gallon of formulation is prepared by the interfacial reaction of polymethylene polyphenyl isocyanate with a polyfunctional amine selected from ethylenediamine, diethylenetriamine, triethylenetetramine, 1,6-hexanediamine, and their mixtures in an aqueous phase optionally containing from 0.05 to 0.25 weight percent of a xanthan gum viscosity modified/stabilizer. Several such formulations and the method of their preparation are described.
