Cucumber Mosaic Virus is a ubiquitous pathogen and a member of the genus Cucumovirus from the family Bromoviridae. It is a globally distributed pathogen responsible for causing disease and severe yield and quality losses in various vegetables and pulse crops, ornamentals, medicinal plants and weeds reported in world. The present study, conducted during Rabi-2024 at the Department of Plant Pathology, College of Agriculture, Latur to evaluate the efficacy of management strategies involving insecticides, chemicals, oils and plant extract in managing CMV in cucumber. Results indicated that different insecticides including (Imidacloprid 17.8 SL, Thiamethoxam 25 WG and Dimethoate 30 EC), chemicals (Salicylic acid), oils (Neem oil and Karanj oil) and Clove extract were used. Among these treatments, (T₁) imidacloprid 17.8 SL was found to be the most effective in reducing disease incidence by 48.66%, lowering mean aphid population to 1.98 aphids/leaf and achieving the highest yield (16.23 t/ha) as compared to untreated control. This demonstrates the strong potential of systemic insecticides in achieving rapid and consistent pest control under conventional farming practices. Treatment (T₆) Karanj oil was the least effective, with mean disease incidence of 23.11%, mean aphid population of 3.22 aphids/leaf and yield of 13.62 t/ha.
