Biorational management of citrus leaf miner (Phyllocnistis citrella) under shade net nursery of Nagpur mandarin

Abstract

The set of treatments were evaluated for the assessment of percentage reduction in leaf infestation caused by citrus leaf miner on 3, 7 and 10 days after each application of insecticidal modules and the percentage of larval mortality calculated on 3,7 and 10 days after each insecticidal modules. The application of clothianidin 50% WDG @0.005% followed by azadirachtin 10,000 ppm @ 0.5ml was found to be the most effective and statistically superior treatment in term of maximum mortality of larval population and minimum infestation of citrus leaf miner on grafts of Nagpur mandarin. The next set of treatments in descending order of efficacy were imidacloprid 17.8 SL @ 0.005% followed by Neem oil 1%, azadirachtin 10000 ppm @ 0.5ml followed by clothianidin 50%WDG @ 0.005%. Application of all the test materials was gave significant reduction in infestation. These test materials confirmed to more effective in reducing the damage and increasing citrus yield.
