摘要：This study aimed at finding out the efficacy of electrostatic sprayer on pest control in comparison with mist blower and air compression sprayer. Six pests were selected based on specific characteristics viz. integumental, movement and ecological niche. Energy use efficiency in production and application of pesticides used by different sprayers for the control of selected pests were quantified based on application efficiency, pre and post pest count and reoccurrence of pest infestation after spray. The greenhouse gas emission for the total energy usage for the corresponding quantity of pesticide were computed for all the selected sprayers. The energy use efficiency of electrostatic sprayer was found to be 1.5 times more than that of mist blower and 2 times more than that of air compression sprayers. The chemical usage by electrostatic sprayer was reduced by 65%, and that of knapsack mist blower was 35% with air compression sprayers. The corresponding greenhouse gas emission was only 20% for electrostatic sprayer and 65% for powered mist blower than that of air compression sprayers. The post pest count was almost nil in all the categories of pest while applying with electrostatic sprayer and the reoccurrence of the pest to the threshold level was minimum. This contributes a significant reduction in emission of CO2 when considered globally, and ultimately contribute to mitigation of global warming.
