Evaluation of effectiveness of various insecticides for the management of citrus Psylla, Diaphorina citri Kuwayama


Author(s): Deepika Chauhan and Poonam Srivastava

Abstract: The study was commenced with the objective to evaluate the effectiveness of various insecticides against citrus psylla, Diaphorina citri during the year 2014-2015 at Pantnagar. Insecticides employed for the evaluation are Novaluron 10 EC, acephate 75 % SP, thiamethoxam 25% WG, acetamiprid 20% SP, spinosad 45 % SC, imidacloprid 17.8% SL, neem (5%). The relative efficacy of each treatment was assessed on the basis of per cent reduction over control where the per cent reduction of nymphal population was recorded to be significantly highest with 91.78 per cent in imidacloprid recording lowest number of 0.66 nymphs/twig/plant at 11 days after 2nd application. During the year 2015 imidacloprid caused highest reduction in the population of psylla nymphs with highest per cent reduction of 74.62 per cent. After 1st application thiamethoxam was found most effective in reducing the population of adults of citrus psylla with highest per cent reduction (77.59 %).
