Comparative Analysis of the Effect of Different Insecticide Treatments on Nagpur Mandarin in Biomass Accumulation

The Comparative Analysis of the Effect Different Insecticide Treatments in Nagpur Mandarin on Biomass Accumulation was conducted during Ambia bahar 2009-10. experiment carried out an eight-year-old mandarin orchard with a spacing 6.0 m x at Futala farm, College Agriculture, Nagpur. study aimed to assess impact different insecticide treatments Citrus psylla management. A trial comprising eleven set Randomized Block Design (RBD), replicated thrice, each treatment plot having four plants. Four branches were selected from plant random and tagged. population citrus (both nymph adult) counted twigs 5 cm fresh growth shoot all sides 2009-2010. found that imidacloprid 0.25 ml/l, acetamiprid 0.1 g/l, quinalphos 1 ml/l + karanj oil (pongamia oil) 10 most effective based biomass accumulation (wet weight basis). Meanwhile, lower efficacy Verticillium lecani 4 g/l mineral azadirachtin 2 g/l. Furthermore, application thiomethoxam be dry basis. results indicated imidacloprid, acetamiprid, thiomethoxam, promoting higher new flush, bearing (buds, flowers fruit), both wet Among them, effective.
