Evaluation of Compatibility of Metarhizium rileyi (Farlow) Kepler (Hypocreales: Clavicipitaceae) with Novel Insecticidal Molecules

Abstract

The compatibility of the entomopathogenic fungus Metarhizium rileyi (Hypocreales: Clavicipitaceae) with selected new generation insecticides was evaluated to support its integration in pest management programs. Eight insecticides Chlorantraniliprole 18.5 % SC, Flubendiamide 39.35 %SC, Emamectin benzoate 5 % SG, Spinosad 48 % SC, Indoxacarb 15 % SC, Profenophos 50 % EC, Diafenthiuron 50 % WP, and Spinetoram 11.7 % SC were tested at their recommended field concentrations. Fungal growth was assessed 14 days post-inoculation to determine the impact of each insecticide on M. rileyi viability. Significant variation in growth inhibition was observed among the treatments. Chlorantraniliprole 18.5 % SC exhibited the highest compatibility, causing only 24.01 % growth inhibition, whereas Indoxacarb 15 % SC recorded the highest inhibition at 68.91 %, indicating low compatibility. These findings highlight the potential for selective use of insecticides in conjunction with M. rileyi to enhance the sustainability of integrated pest management strategies.
