Abstract:
The experiment on, “efficacy of different insecticides against citrus leaf miner (Phylocnistis citrella) on acid lime (Citrus aurantifolia).” was undertaken at Horticultural farm of Krishi Vigyan Kendra, Dahigaon ne and College of Agriculture, Dhule during 2020-2021. The experiment was planned out in Randomized Block Design with ten treatments and three replications. The variety used for study was Phule Sharbati. Total ten treatments were used in present investigation consisting of insecticides viz, spirotetramat 120 SC + imidacloprid 120 SC @ 0.5 ml/l, cyantraniliprole 10.26 OD @ 1.8 ml/l, abamectin 0.15 EC @ 0.37 ml/l, spinetoram 11.7 SC @ 0.5 ml/l, buprofezin 25 SC @ 1.25 ml/l, spinosad 45 SC @ 0.3ml/l, acetamiprid 20 SP @ 0.3 g/l, neem formulation azadirachtin (10000 ppm) @ 3.0ml/l, emamectin benzoate 5 SG @ 0.25 g/l and untreated control. As regards the efficacy of different insecticides, all the insecticides were significantly superior over untreated control in recording the lowest percentage of citrus leaf miner per cent infestation.
Average effect revealed that, lowest larval count were recorded in treatment spinosad 45 SC (3.03 larvae / 15 cm apical twig) was significantly superior and it was found at par with the treatments spinetoram 11.7 SC, cyantraniliprole 10.26 OD and spirotetramat 120 SC+ imidacloprid 120SC recording 3.60, 4.26 and 4.23 larvae / 15cm twig respectively. The next better treatments in order were abamectin 0.15 EC (4.86), acetamiprid 20 SP (5.06), buprofezin 25 SC (5.40), emamectin benzoate 5 SG (5.60) and azadirachtin (10000 PPM) (5.90) citrus leaf miner larvae / 15cm apical shoots, respectively.
