Ridge gourd [Luffa acutangula (Roxb.) L.] is an important vegetable crop and it is grown in different parts of India. The field trials were conducted during rainy season of 2018 and 2019 to test efficacy of botanicals and inorganic salts against management of mosaic disease in ridge gourd. In this study, naturally infected leaf samples exhibiting characteristic mosaic disease symptoms were collected during experiments. Among 11 treatments, imidacloprid (@ 0.05%) was found the most efficient treatment against mosaic disease with minimum per cent disease index (15.90%) and per cent disease reduction (61.69%). Next best treatment was neem leaf extract (@ 10%) with per cent disease index of 19.34 % and per cent disease reduction of 53.41%, followed by tumba fruit extract @ 10% (21.18% PDI and 48.97% disease reduction). Least effective treatment was borex (500 ppm) with PDI of 36.89%, followed by salicylic acid (500 ppm) with PDI of 35.36% against mosaic disease on ridge gourd in pooled data.
