Field experiments were conducted during Kharif 2016 and 2017 to manage yellow vein mosaic virus in Okra with seven modules along with one control. The module consists of use of either seed treatment or yellow sticky trap singly or in combination with neem oil (bio-pesticide), one insect growth regulator and two new generation insecticides to manage the vector population of whitefly which transmit the disease. Lowest mean population of whitefly(3.74/3leaves) and lowest YMV infected plant of 3.7% was found in seed treatment with imidacloprid 600FS @ 5ml/kg of seed, installation of yellow sticky trap @ 50 traps/ha and spraying of diafenthiuron50% WP @ 1 gm / Lit with 41.74% increase in yield and BC ratio 1.86 followed by whitefly population of 6.22/3leaves and % YMV affected plant of 5.38 in seed treatment with imidacloprid 600FS, installation of yellow sticky trap and spraying of acetamiprid 20 SP @ 0.3 gm / Lit with 35.26% increase in yield and BC ratio of 1.82 as compared with control of whitefly population102.9/3leaves, % YMV affected plant of 38.44 and BC ratio of 1.45. The whitefly population, % disease incidence in other treatments, were more but % increase in yield over control and BC ratio were lower than the above two treatments. Highest number of natural enemies like spider and lady bird beetle was found in control followed by neem oil, only seed treatment, yellow sticky trap and lower population of natural enemies in insecticide treated plots.
