World crop yields are reducing every year between 20 to 40% due to the damage wrought by plant pests and diseases. Crop protection is essential to reduce loses of yield. Among all the crop protection methods, chemical protection usage growing effectively as of its immediate action, low cost and reduces human drudgery. Chemical protection of crop carried out by dust or spray form. To spray pesticides on crop, low hp tractor operated wiper sprayer was developed instead of using conventional equipment to reduce operating cost, time and drudgery. In laboratory condition, uniformity coefficient of developed wiper sprayer was found to be 89.9 %. The average effective field capacity, field efficiency, fuel consumption and application rate of developed wiper sprayer in the field of groundnut was found to be 0.9072, 1.4899, 2.0618 ha h-1, 80, 78.83, 77.92%, 1.513, 1.018, 0.815 l ha-1 and 423, 253, 181 l ha-1 at forward speeds of 1.5, 2.5 and 3.5 km h-1. Cost economics of developed wiper sprayer was found to be 310.2, 197.61 and 150 Rs. ha-1 at forward speeds of 1.5, 2.5 and 3.5 km h-1.Saving of labor cost (%) and time (%) over conventional method of spraying found to be 101.5, 216.27, 316.67 % and 1714, 2880, 4023 % at forward speeds of 1.5, 2.5 and 3.5 km h-1. Operating speed of 3.5 km h-1 was given best performance.
