Studies on Compatibility of Metarhizium anisopliae with Insecticides

Abstract

The results on the compatibility of M. anisopliae (isolate TNAU-MA-GDU) with various insecticides at five different doses (0.1x, x, 2x, 5x, and 10x) revealed that the highest mycelial growth was observed in flubendamide 480 SC (89.00 to 78.8 mm) and spinetoram 11.70 SC (89.00 to 76.60 mm) and was significantly superior over rest of insecticides tested. The minimum growth of M. anisopliae was observed in insecticidal treatment with azadirachtin (Neem 1500) (65.2 to 18.2 mm) followed by novaluron 10 EC (86.6 to 42.1 mm). All the tested insecticides except azadirachtin (Neem 1500) were compatible with M. anisopliae (TNAU-MA-GDU) at lower and field doses. The results on the compatibility of insecticides with M. anisopliae clearly indicate that the pesticides having better compatibility exhibited the maximum mycelial growth, sporulation, and biomass production in order of flubendiamide 480 SC > spinetoram 11.70 SC > emamectin benzoate 5 SG > chlorantraniliprole 18.5 SC > novaluron 10 EC > azadirachtin (Neem 1500).
