What aspect of nozzles is important for ensuring effective pesticide application?

The aspect of nozzles that is crucial for ensuring effective pesticide application is their ability to control the amount of material applied. Nozzles play a critical role in determining the spray pattern, droplet size, and application rate of the pesticide. By controlling how much pesticide is released at any given time, nozzles help achieve the desired coverage on plants, ensuring that the pesticide is absorbed effectively while minimizing waste and environmental impact. Proper calibration and selection of nozzles directly influence the efficacy of the treatment, making it essential for pesticide applicators to understand how nozzles function and their impact on application rates.
