Abstract: Investigations were carried out to evaluate influence of some selective insecticides on mycelial growth and conidial germination of Metarhizium anisopliae (Metsch.) Sorokin and Paecilomyces fumosoroseus (Wize) Brown & Smith. All insecticides significantly inhibited mycelial growth and conidial germination of the fungal pathogens. Lorsban was the most toxic insecticide to mycelial growth and conidial germination followed by Lannate, Larvin and Pirate. Cascade, Match, Steward and Proclaim were comparatively less toxic to mycelial growth (36.78-48.67% inhibition) and conidial germination (40.32-49.97% inhibition) of the fungal pathogens. Conversely, Runner, Capture, Abamectin and Curacron were compatible with significantly lesser inhibition in growth (25.19-36.47%) and conidial germination (27.78-43.66%) of the fungi. Tracer was found safe to conidial germination and growth of the fungi.
