In for all intents and purposes all cases this was accounted for as the most significant application system. The underarm switch worked type is generally mainstream yet shoulder siphon sprayers and pressure or pneumatic sprayers were likewise referenced. Backpack sprayers are utilized to apply any sort of pesticide (for example generally bug sprays, trailed by fungicides and herbicides). Water volumes extend from 100 to 400 l/ha. In all likelihood in view of the costs in question, a sprayer is all the more regularly utilized on money yields, for example, cocoa, maize and cotton, and furthermore on garden crops and to a lesser degree on the staple nourishment crops.

·         Battery operated Sprayer
Battery opearted sprayers utilize a plastic pivoting circle, fueled by batteries, to scatter the splashing fluid into exceptionally little beads. Application volumes can be as low as 3 liters for every ha which is a significant preferred position in instances of water shortage and furthermore their relative basic system and usability have added to the across the board utilization of turning plate sprayers.
