4. INTRODUCTION A Sprayer is a device used to spray a liquid. In agriculture, a Sprayer is a piece of equipment that used to spray pesticides on the farm lands. These sprayers reduces the human effort. Sprayers range in size from man portable range typically backpacks and spray guns.

5. PROBLEM STATEMENT To design and fabricate a proposed model for automated pesticides sprayer. One of the difficult task in farming is to prevent the crop without any pests. This task simply replaced by a Automated sprayer which reduces the farmer effort.

6. LITERATURE SURVEY Performance of a chemical injection sprayer system, found the time delay of concentrated pesticides through injection sprayers to be significant, and proposed injection at the individual nozzles as a possible solution to shorten delays. Development of a direct nozzle injection system that overcame the concentration variation problems reported by previous researchers. Simulations are used to compare chemical application accuracies for various designs of injection sprayers. They found that reducing the diameter of the fluid lines near the end of the spray booms improved overall application accuracy. An autonomous mobile robot for use in pest control and disease prevention applications in commercial greenhouses.

12. ADVANTAGES A sprayer gives you easy access to these areas by delivering an efficient coating, all through the squeeze of a trigger. As much as your sprayer is great for coating a surface in Wet and Forget, it can also be used for leaf fertilizers and substances to protect plants in your garden. Rather than pouring it on and wasting it, you can be a lot more frugal with your cleaning solution by utilizing a sprayer that will only allow an appropriate amount to be released with every squeeze. Forget using a sponge or brush of some description, a sprayer can give you something that any handheld implement.

13. CONCLUSION No design is ever perfect for all the time; design needs to be changed as per the needs and wants of users. Inputs for new product development and or design improvements are obtained from the user’s feedback and product evaluation with respect to user requirements. Identify the circumstances under which chemical pesticides may be required in future pest management. Determine what types of chemical products are the most appropriate tools for ecologically based pest management. Explore the most promising opportunities to increase benefits and reduce health and environmental risks of pesticide use.
