A comprehensive study was carried out on the effect of power (batteries) on the droplets with the objectives to minimise dose rate and maximise mortality, by avoiding the wastage of pesticides. Droplet distributions were obtained over a range of rotation speeds by using different nozzles. The data obtained using various batteries indicate that the speed was directly proportional to numbers of batteries used while the droplet size was inversely proportion to the speed of disc. With increasing problems in controlling some cotton pests, particularly those on the under-surface of leaves, these results indicate that it may now be worth re-exploring the issue of using charged sprays.
