Abstract: Entomological studies have established that in numerous cases, smaller droplets of pesticide spray provide greater biological efficacy per unit mass of pesticide than do the larger droplets for achieving insect control. Thus, the recent concept of spraying is to spray the target pest more efficiently by selecting optimum droplet size and density for maximum retention and coverage. Customarily, more chemical than theoretically needed is often applied due to the variability in field conditions and the need to ensure complete coverage. In such a situation, Variable rate spraying system and the Electrostatic spraying system can be effectively utilized. The variable rate sprayers and air-atomizing electrostatic sprayers are overcoming the deficiencies of conventional sprayers. The variable rate pesticide spraying has the potential to reduce pesticide amount and cost as well as off target contamination of environment. Electrostatic charging increases spray deposit level, reduces waste and greatly improves spray distribution for better insect and disease control. Therefore the use of these two technologies can ensure the spraying of pesticides within in acceptable limit and ensure residue free farm produce for healthy life of human being
