Weed control is one of the most time-consuming tasks, and manual weeding is inefficient due to labor costs, time, and tedium. Chemical weed management technologies have helped to alleviate these negative aspects. However, the growth of herbicide-resistant weeds, their environmental impact, and the growing desire for chemical-free foods have encouraged researchers to investigate alternate weed management strategies. A prototype of a walking-type battery-operated boom sprayer cum weeder was developed. The attachment was made to suppress inter-row weed plants mechanically. A brushless dc motor powers the mechanical weeding attachment. One of the most challenging aspects of this project was appropriately designing the weeding attachment and the sprayer for spraying. Both attachments would be joined with a machine to do mechanical weeding and spraying without affecting the crops. In this paper, various researches on sprayers, weeders, and combined configurations of sprayers & weeders have been discussed along with their working principles.
