Online published on 3 December, 2015. Abstract Field experiments were conducted to evaluate the efficacy of Integrated Pest Management (IPM) modules against mango hopper during 2009–10 to 2012–13 in south Gujarat region. The module-V consisting first spray of acephate (0.04%) at panicle emergence stage followed by second spray 21 days after first spray with spinosad (0.004%) and third need based spray of carbaryl (0.15%) was found to be the most effective in reducing the hopper population (3.81 hoppers/twig or panicle). This was followed by module-III (4.35 hoppers/twig or panicle) containing first spray of thiamethoxam (0.008%) at panicle emergence stage followed by second spray 21 days after first spray of profenophos (0.05%) and third need based spray of carbaryl (0.15%) and module-IV (4.91 hoppers/twig or panicle) first spray of spinosad (0.004%) at panicle emergence stage followed by second spray 21 days after first spray with thiamethoxam (0.008%) and third need based spray of Neem Azal (10000 ppm @ 3 ml/lit. of water). The maximum number of fruit set at marble stage was recorded in module-Vfruits set at harvest stage was highest in module-V followed by module-III. Highest yield was recorded in module-V (72.63 kg/tree). Top Keywords Mango hoppers, modules, spinosad, thiamethoxam, IPM. Top |
