in greenhouse gas emission. Hence it is important to develop a clear
understanding of our emission inventory towards reducing greenhouse gas
emissions. Pesticide application play a major role in the greenhouse gas emission.
Environmental hazards associated with pesticides results from over application
and off-target movement of toxic pesticides from inefficient spray application.
The introduction of electrically charged sprays for agricultural application can
provide greater control of droplet transport with impending reduction of wastage.
The study aims to find out the efficacy of electrostatic sprayer on pest control in
comparison with mist blower and air compression sprayer. Six pests were viz.
pumpkin beetle, cowpea aphid, curcurbit fruit fly, brinjal mealy bug, caterpillar
and chilli mite 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 of sprayers, Pre and Post
pest count and the 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. In 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 contribute a significant
reduction in emission of CO2 when it considered globally, ultimately contribute in
mitigation of global warming.
