Compatibility of Metarhizium anisopliae with new generation insecticide in vitro condition

Abstract

The present investigation was carried out during rabi 2013-2014 at the Entomology laboratory, College of Agriculture JNKVV, Jabalpur at Completely Randomized Block Design (CRBD). The experiment on compatibility studies was undertaken on four treatments and five replication with new generation insecticides. The effect of new generation insecticide on the mycelial growth of Metarhizium anisopliae was conducted in In vitro. Among the new generation insecticides tested the emamectin benzoate 5 SG was found to be most compatible with least inhibition percentage followed by flubendiamide 20 SC and rynaxypyr 20 SC. Although the different new insecticide tested in the present investigations slightly inhibited the growth of M. anisopliae in poisoned media, the combined use of the fungus and new generation insecticide cannot be completely ruled out. All the insecticides tested have been combined at half recommended dose with entomopathogenic fungi to explore the possibility of increasing the efficacy of the combinations for pest control.
