    • Pesticidal formulations of cadusafos are provided. An aqueous capsule suspension is provided, containing from about 150 to about 360 grams of cadusafos per liter of formulation and having lower mammalian toxicity than aqueous cadusafos microemulsion formulations is prepared by interfacial polymerization of a first polyfunctional compound, such as a polymethylene polyphenyl isocyanate, with a second polyfunctional compound, such as a polyfunctional amine or mixtures of polyfunctional amines, in an aqueous phase optionally containing from about 0.05 to about 0.50 xanthan gum viscosity modifier/stabilizer. A granular form of the microencapsulated cadusafos is also provided. Several such formulations and the method of their preparation are described.
