In vitro effect of phytoextracts against Phomopsis vexans causing Phomopsis blight of brinjal

Abstract

Brinjal is one of the most important vegetable that is grown and cultivated all around the globe. Its infected with a plethora of pathogens one of which is the deadly fungi Phomopsis vexans that is the incitant of Phomopsis blight and fruit rot disease of brinjal. The present study was carried out to evaluate the antagonistic properties of various easily available phytoextracts against the pathogen. The effect of nineteen different phytoextracts was tested in vitro by poisoned food technique, among which Allamanda registered maximum inhibition per cent of 89.13% and 91.43% at 15% and 20% respectively followed by garlic with an inhibition per cent of 84.22% and 88.81% which were significantly different from each other. The least inhibition was observed in Lantana with an inhibition per cent of 64.16% and 72.27% at 15% and 20% respectively. All the other treatments were significantly at par.
