What should be done if a nozzle is found to be dispensing too much pesticide?

When a nozzle is dispensing too much pesticide, it is essential to adjust the application methods to ensure effective and safe treatment. All three measures mentioned can contribute to achieving the desired application rate.

Increasing ground speed can help reduce the amount of pesticide applied over a given area, as the product is dispersed more quickly. This adjustment can be beneficial if the nozzle is delivering too much pesticide within a specific timeframe.

Decreasing liquid pressure is another effective approach. Lowering the pressure at which the pesticide is expelled from the nozzle directly impacts the flow rate. A reduction in pressure can lead to a finer mist or a smaller volume of liquid being released, thus reducing the total amount applied.

Changing to a smaller nozzle is a practical solution because smaller nozzles typically deliver lower flow rates. By switching to a nozzle designed for smaller volumes, the applicator can ensure that the pesticide is applied more judiciously, aligning the application rate with the recommendations for the specific pesticide and the target area.

Therefore, all three actions—adjusting ground speed, decreasing liquid pressure, and switching to a smaller nozzle—are valid responses to the issue of excessive pesticide dispensing. Implementing any combination of these strategies can help correct the situation and ensure proper pest control while minimizing environmental risks.
