In-vitro efficacy of fungicides against Phomopsis vexans caused Phomopsis blight in Brinjal

Abstract

Phomopsis blight caused by Phomopsis vexans is one of the major constraints in the production of brinjal. In order to find out the effective fungicides against Phomopsis vexans experiment was carried out in-vitro evaluation of fungicides. The results of present investigation revealed that the maximum growth inhibition after seven days against Phomopsis vexans in-vitro condition was recorded in the treatment of carbendazim 87.46 per cent followed by propiconazole 86.29 per cent. Other fungicide treatments growth inhibition recorded hexaconazole and tebuconazole whereas 72.18 per cent and 64.83 per cent respectively. Copper oxychloride showed growth inhibition 54.20 per cent and minimum growth inhibition was noticed in copper hydroxide 47.40 per cent and this treatment.
