In vivo efficacy of fungicides were assessed against Phomopsis vexans causing Phomopsis blight of brinjal. The tested fungicides were Carbendazim 50 % WP, Propiconazole 25 % EC, Hexaconazole 5 % EC, Mancozeb 75 % WP, Propineb 70 % WP, Carbendazim 12 % + Mancozeb 63% WP, Carboxin 37.5% + Thiram 37.5% WP and Pyraclostrobin 13.3% + Epoxiconazole 5 % SE. Field trials were conducted during Kharif 2024 in the experimental field of Department of Plant Pathology, College of Agriculture, Latur using Pusa Purple Round variety of brinjal. The trial was laid out in Randomized Block Design with three replications. After the third spray Seedling dip with Carboxin 37.5% + Thiram 37.5% WP and Spray Carbendazim 50% WP showed least disease severity of 16.27 % and showed highest disease control 63.25% respectively over the untreated control plot. The same treatment resulted in maximum fruit yield of 28.96 t/ha registering 60.00 % increase in yield over the untreated control plot with ICBR of 1:25.91. The second best treatment was Seedling dip with Carboxin 37.5% + Thiram 37.5% WP and Spray Carbendazim 12% + Mancozeb 63% WP showed disease severity of 16.53 % and showed disease control 62.66 % respectively over the untreated control plot with fruit yield of 28.60 t/ha registering 58.01 % increase in yield over the untreated control plot with ICBR of 1:20.74 followed by Seedling dip with Carboxin 37.5% + Thiram 37.5% WP and Spray Hexaconazole 5% EC showed disease severity of 16.80 % and showed disease control 62.05 % respectively over the untreated control plot with fruit yield of 28.59 t/ha registering 57.96 % increase in yield over the untreated control plot with highest ICBR of 1:26.00. These treatments were at par with each other and significantly superior over rest of the treatments. The untreated control plot recorded maximum disease severity of 44.27 % and lowest fruit yield 18.10 t/ha.
