    Abstract

    The advent of commercial mycoinsecticides — insect pathogenic fungi used as insecticides — creates new paradigms in formulating these organisms. The “active ingredient” (conidium, blastospore, or preserved mycelium) must be kept alive and infectious yet dormant in the formulation for a commercially acceptable shelf-life under ambient conditions. The inherent conidial hydrophobicity of most of the current candidate fungi must be overcome for many applications without killing the fungus. Formulation additives or spray adjuvants cannot interfere with the infection process. The fungal active ingredient must be kept alive as long as possible on the plant surface in the face of lethal solar irradiation.
