Effect of chemical control of phomopsis blight of brinjalcaused by Phomopsis vexans

Abstract

Experiment was conducted to assess the efficacy of different fungicides against Phomopsis blight of brinjal caused by Phomopsis vexans in-vivo conditions. Among all the tested fungicides the minimum disease intensity and maximum per cent disease control was recorded after third spraying with 0.1 per cent carbendenzim (10.35% & 69.25%)and followed by 0.05 per cent propiconazole (11.41% & 66.10%) this treatment remains at par with each other and significantly superior over rest of the treatments. The higher yield of brinjal fruits was obtained with 0.1 per cent carbendenzim i.e. 185.52 q ha-1 and followed by 0.05 per cent propiconazole i.e. 183.78 q ha-1. But the highest incremental cost:benefit ratio 1:14:8 was recorded by 0.05 per cent propiconazole due to lowest market prize on Phomopsis blight of brinjal.
