Present investigation entitled “Varietal preference of mango leaf hoppers and its management through biopesticides” was conducted at the Horticultural mango orchard, B.T.C. College of agriculture and research station, Bilaspur, Chhattisgarh during November-2020 to May-2021.

Among the insecticide’s treatments in first spray, the Imidacloprid was found most effective to controlling leaf hoppers with least leaf hopper population (3.04/twig/panicle) followed by Azadirachtin (7.49/twig/panicle) and Neem oil (9.27/twig/panicle). Among microbial treatments Verticillium lecanii was found most effective with minimum leaf hopper population (10.66/twig/panicle) followed by Metarhizium anisoplae (11.71/twig/panicle) and maximum leaf hopper population was recorded in treatment of Beauveria bassiana (12.64/twig/panicle). The untreated control showed significantly highest leaf hopper population (19.33/twig/panicle).

In second spray, the imidacloprid was found most effective to controlling leaf hoppers with least population (2.47/twig/panicle) followed by Azadirachtin (6.96/twig/panicle) and Neem oil (8.65/twig/panicle). Among microbial treatments Verticillium lecanii was found most effective with minimum hopper population (9.30/twig/panicle) followed by Metarhizium anisoplae (10.26/twig/panicle) and maximum hopper population was recorded in treatment of Beauveria bassiana (10.56/twig/panicle). The untreated control showed significantly highest hopper population (13.85/twig/panicle).
