Efficacy of ipm modules against mango hopper complex

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).
