The correct answer is: All of the above

One of the key functions of spray nozzles is to serve multiple purposes that enhance the effectiveness and efficiency of pesticide application. These nozzles are designed to regulate the flow of liquid, ensuring that the right amount of pesticide is delivered according to the application requirements. Additionally, they atomize the liquid stream, which involves breaking it into fine droplets, increasing the surface area for better coverage on targeted pests or plants. Furthermore, spray nozzles can spread droplets in a specific pattern to enhance uniformity and precision during application, which is crucial for achieving the desired results while minimizing waste and environmental impact. By fulfilling all these essential functions, spray nozzles play a vital role in ensuring that pesticides are applied effectively, with proper dosage, coverage, and reduction of drift.
