dc.description.abstractPresent investigations on “Studies on Pest Complex and Management of Major Pests of Jasminum sambac cv. Mysuru Mallige” were undertaken at College of Horticulture, Mysuruand surrounding region during the year 2017-18. Four sucking pests namely thrips, blossom midge, brown spotted stink bug and tingid bug, two defoliator pests such as leaf web-worm and sphingid moth, three borer pests which are bud borer,bud and shoot worm, shoot web-worm,and one mite pest, red spider mitewere recorded on Mysuru Mallige in field survey conducted at Mysuru. Seasonal incidence of major pests of Jasminumsambac cv. Mysuru Mallige revealed that, the bud borer incidence was maximum during August, 2017 month with positive significant correlation with minimum temperature, whereas bud and shoot worm incidence was maximum in the month of January, 2018 and had negative significant relationship with minimum temperature. Peak incidence of shoot web worm and leaf web worm was noticed during October, 2017 and November, 2017 months, respectively with both having positive significant correlation with morning and evening relative humidity and negative significant correlation with maximum temperature. Peak population of mite and thrips was recorded during April, 2018 and May, 2018 months, respectively. Both pests had positive significant correlation with maximum temperature and negative significant correlation with morning and evening relative humidity. Among seven insecticides evaluated against bud borer and leaf web worm, chlorantraniliprole 18.5% SC @ 0.2 ml/l, spinosad 45% SC @ 0.3 ml/l, flubendiamide 39.35% SC @ 0.25 ml/l and quinalphos 25% EC @ 2 ml/l recorded lower mean percent affected buds and leaves with higher yield (2058 Kg/ha) and cost benefit ratio (1: 3.62). Out of seven acaricides evaluated against red spider mite,etoxazole 10% SC @ 1 ml/l, spiromesifen 22.9% SC @ 0.8 ml/l, fenazaquin 10% EC @ 2.5 ml/l and propergite 57% EC @ 2.5 ml/l recorded lower mite population with higher yield (2230 Kg/ha) and cost benefit ratio (1: 3.80).en_US
