Texas Aerial Application of Pesticide Practice Exam

To minimize drift-sized droplets while maintaining pressure, adding more nozzles is an effective approach. By increasing the number of nozzles, the overall application rate can be maintained without the need to increase the pressure. This is important because higher pressure can lead to smaller droplet sizes, which are more prone to drift when subjected to wind.

When more nozzles are used, the same volume of liquid can be distributed over a larger area at a lower pressure. This allows for the creation of larger droplets that are less susceptible to drifting and can ensure better coverage on the target area. The strategy of diversifying the distribution through multiple nozzles allows aerial applicators to optimize their operation for accuracy and efficacy while reducing the risk of pesticide drift during aerial applications.
