Design and Development of Grape Yard Pesticide Sprayer

India is an agricultural nation. India’s population is growing, as we all know, and agricultural sector modernization is crucial to meet the country’s growing demand for food. Farmers in our nation use fertilizers, pesticides, and insecticides on their crops to get rid of weeds and other undesirable plants. They also employ substances to get rid of mice and rats and manage a range of insects and bacteria. Fertilizers are manually applied in the traditional manner by farmers using backpack sprayers. It can be perilous and is quite damaging to their health. The required work is rather more difficult. There are pesticide spraying machines on the market, therefore there is no problem. However, farmers cannot afford the exorbitant expense of purchasing two different pieces of equipment for spraying pesticides and fertilizer. Therefore, cost optimization that can improve the Farmer’s financial situation with developing multipurpose pesticide sprayer is the main emphasis of our work.
