Why is there an operating pressure range for each type of nozzle?

The operating pressure range for each type of nozzle is crucial primarily to maintain the integrity of the spray pattern. Each nozzle is designed to deliver a specific flow rate and droplet size at a set pressure, which ensures that the application is both effective and efficient. When the pressure is too low, the nozzle may not produce enough spray volume, leading to inadequate coverage. Conversely, if the pressure is too high, the droplets may become too fine, resulting in drift and uneven application.

In addition to ensuring optimal spray patterns, maintaining the recommended pressure helps to provide consistent performance across different environmental conditions, allowing for uniformity in pest management practices. A well-maintained spray pattern is essential for effective pest control, as it allows for proper crop coverage and minimizes off-target application. This contributes to both effective pest management and conservation of beneficial organisms within the ecosystem.
