The present investigation was undertaken to assess the efficacy of different newer molecule of insecticides against citrus leaf miner in nursery on Nagpur mandarin grafts. The experiment was conducted during September-October 2012 at Centre of Excellence for Citrus (Indo- Israel Project) Horticulture Section, College of Agriculture, Nagpur. The investigation was conducted with treatments; Abamectin 1.9 EC (0.003%), Acetamiprid 20 SP (0.04%), Diflurobenziron 25 WP (0.08%), Dimethoate 30 EC (0.04%), Imidacloprid 17.8 SL (0.005%), Spinosad 45 SC (0.03%), Thiamethoxam 25 WG (0.06%) and Control (water spray). Observations were recorded with counting infected and total leaves from randomly selected five plants from eachblock and revealed that, the infestation of citrus leaf miner was mostly observed on sprouted leaves of citrus. Similar trend of the effect of different new molecules of insecticide was observed against citrus leaf miner in nursery at 3 DAS and 7 DAS of each application. Amongst the different new molecule of insecticides tested, Thiamethoxam 25 WG (0.06%) was significantly superior over all treatments recording cumulative lowest (4.50 per cent) leaf miner infestation. The Abamectin 1.9 EC (0.003%) was second in order of merit which exhibited 6.22% leaf miner infestation and found significantly superior to the following treatments viz, Spinosad 45 EC (0.03%), Acetamiprid 20 SP (0.04%), Imidacloprid 17.8 SL (0.005%), Diflubenzuron 25 WP (0.08%), and Dimethoate 30 EC (0.03%) recorded cumulative per cent leaves infestation of citrus leaf miner in the range of 9.71 to 14.57 per cent, respectively.
