Abstract:

The investigation examined the effectiveness of various insecticide modules against citrus leaf miner infestation in a citrus nursery. These modules included Azadirachtin 1500 ppm combined with different chemical agents. Incidence of citrus leaf miner on Nagpur mandarin seedlings commenced in the 36th meteorological week at 14.96% infestation, peaked at 70.25% in the 42nd week, and subsequently declined. Infestation was notably higher in newly sprouted leaves during the 41st and 42nd weeks, showing significant positive correlation with evaporation and non-significant positive correlation with high temperature, and negative correlation with low temperature, morning and evening relative humidity, and rainfall. The cumulative effect of three applications across all modules revealed that Module-2 (Azadirachtin 1500 ppm combined with Thiamethoxam 25 WP and Thiamethoxam (12.6%) + Lambdacyhalothrin (9.5%) ZC) exhibited the lowest leaf infestation rate at 13.73%, significantly superior to the control. Module-7 followed with 14.18% leaf infestation. Modules 1, 4, and 6 were also effective, recording leaf infestation rates of 15.15%, 15.60%, and 15.62%, respectively. Module-5 recorded the highest infestation rate at 18.56%, while the control (water spray) exhibited a maximum infestation rate of 27.43%.
