Author(s): Ganesha Naik R and Jayalakshmi K
Abstract: Among eight fungicides evaluated against Cercospora leaf spot disease of bhendi under field conditions, Propiconazole 25 EC (0.1%) was found significantly superior in controlling the disease. The percent disease index (PDI) was significantly less (11.79) in Propiconazole 25 EC sprayed plot followed by Carbandizim 12% + Mancozeb 63% WP (16.31) and Cymoxanil 8% + Mancozeb 63% WP (19.28) compared to other fungicides and unsprayed control plot (87.85 PDI) respectively. Correspondingly, a maximum fruit yield of 16844.44 kg/ha was recorded in plot in which Propiconazole 25 EC was received followed by Carbandizim 12% + Mancozeb 63% WP (15,888.89 kg/ha) and Cymoxanil 8% + Mancozeb 63% WP (15,500.00 kg/ha) sprayed plots respectively. Whereas, in unsprayed control plot a minimum fruit yield of 11,022.22 kg/ha was recorded. The B:C ratio was also found higher in propiconazole 25EC (1:3.09) Carbandazim 12% + Mancozeb 63% (1:2.58) and Cymoxinil 8% + Mancozeb 63% WP (1:2.37) sprayed plots compare to other fungicides and untreated control plots.
