Cucumber mosaic virus is one of the most devastating and widely distributed pathogen. This was successfully transmitted to indicator plants (chili, tomato and chenopodium) through sap inoculation. After infectivity assay, CMV was inoculated on cucumber plants grown in greenhouse. Management of CMV in cucumber was done with different botanicals (Neem, Eucalyptus) and plant defense activators (Urea, Salicylic acid and milk). These treatments were used 7–10 days after CMV inoculation. Botanicals were used @5m/L, urea @5g/L, salicylic acid @1.5mg/L and milk @1ml/9ml. Among the different treatments neem extract with 15.49% disease incidence was the best in reducing cucumber mosaic virus disease followed by eucalyptus (18.13%), urea (18.65%), salicylic acid (19.46%) and milk (28.12%) in that order. Therefore, neem extract treatment was found to be best for management of CMV.
