Mansukh bhai Jagani of Amreli, Gujarat innovated ‘bicycle sprayer’ which is a highly efficient alternative to knapsack sprayers. The device consists of a chain and sprocket transmission system, pump assembly, tank and adjustable sprayer boom as a kit. The entire kit can be fitted to any conventional bicycle. Additional sprockets are attached to the axles existing in the bicycle. The forward and backward movement of bicycle is transferred to a pump assembly, which pumps air into the pesticide tank to generate pressure for spraying through the sprayer boon nozzles. This sprayer has an adjustable and foldable boom, which can be adjusted for height as well as spraying nozzles’ positions. On the other hand, the conventional sprayers predominantly used by farmers today are the hand sprayers/knapsack sprayers, which require continuous pumping manually by one hand through lever to carry out spraying operation. The whole process of spraying is very tiresome and also leads to hand, back, and neck pains. But bicycle sprayer has solved all the problems and made the work easy and smooth. This device was launched in the market in the year 2005.
