A study was conducted to test the different integrated approaches for management of Downy Mildew of bitter gourd along with bower system and non bower system of planting, Four years pooled data revealed that all the treatments of bower system of planting lowered the disease severity as compared to non bower system of planting. Among the 14 treatments tested, integrated disease management components like seed treatment with ridomil mz (metalaxyl 8%+mancozeb 64%) @ 0.25%+3 (three) times removal of lower infected leaves in the morning and spray of mancozeb 75% @ 0.25% in the afternoon on bower system recorded significantly lowest disease severity of downy mildew (4.7%) with maximum fruit yield of 90.2 q/ha. The same treatment also registered 92.24% disease control over control plots followed by seed treatment with ridomil mz (metalaxyl 8%+mancozeb 64%) @ 0.25% along with one foliar spray of alliete (fosetyl-al) @ 0.25% on bower system of planting registered 79.87% disease control. However, the check plot recorded the maximum disease severity of 60.6% and 46.6% with minimum green fruit yield of 33.5 q/ha and 41.1 q/ha in non bower and bower system of planting respectively.
