The investigation was carried out on “Compatibility of Metarhizium anisopliae with botanicals under laboratory condition” at College of Agriculture, Pune during 2021-22.

Studies on compatibility of Metarhizium anisopliae with botanicals by dual plate bioassay method revealed that Azadirachtin @ 1000 ppm recorded 1.80 per cent inhibition with

M. anisopliae, which was at par with M. anisopliae with NSKE 5 per cent (6.31 %). Next best treatments in compatibility rating were M. anisopliae with Eucalyptus 1 per cent (32.87 %) which was on par with M. anisopliae with Karanj oil 5 per cent (43.24 %). M. anisopliae with Neem oil 5 per cent observed (59.45 %) reduction in germination. Therefore, Azadirachtin and NSKE were highly compatible with M. anisopliae. Eucalyptus oil and Karanj oil were compatible with M. anisopliae. Whereas, Neem oil was partially compatible with M. anisopliae.

Studies on compatibility of M. anisopliae with botanicals by dual liquid bioassay method revealed that M. anisopliae with Azadirachtin @ 1000 ppm recorded least per cent inhibition (9.50 %) which was at par with M. anisopliae with NSKE 5 per cent (23.15 %). Next best treatments were M. anisopliae with Eucalyptus 1 per cent which was on par with M. anisopliae with Karanj oil 5 per cent recorded 33.61 and 27.80 per cent reduction in germination, respectively. Maximum reduction in germination was observed in treatment with M. anisopliae with Neem oil 5 per cent (46.24 %). Thus, Azadirachtin and NSKE were highly compatible with M. anisopliae. Eucalyptus oil and Karanj oil were compatible with M. anisopliae. Whereas, Neem oil was partially compatible with M. anisopliae.
