A microencapsulated insecticidal pathogen for application to vegetation is disclosed. An insecticidal viral, bacterial or fungal pathogen is encapsulated in a polymeric encapsulating agent such as Eudragit L, Eudragit S, Eudragit L or S with Eudragit RL, Eudragit L or S with Eudragit RS, polyacrylates, polyacrylic acids, cyclic acrylate polymer or mixtures thereof. Also encapsulated in the polymeric encapsulating agent is a sunscreening agent such as benzophenone, para amino benzoic acid, benzil, or mixtures thereof. Also disclosed is a process for encapsulating an insecticidal pathogen. The microcapsules of the invention effectively retain sunscreening agent within the capsule and are easily prepared without using toxic materials requiring subsequent removal.
