What is the recommended droplet size for effective aerial pesticide application?

The recommended droplet size for effective aerial pesticide application falls within the range of 100 to 400 microns. This size is optimal for achieving a balance between coverage and drift control. Droplets in this range are large enough to target the intended area effectively, ensuring that the pesticide reaches the plant surfaces and doesn't evaporate or drift excessively due to wind or other environmental conditions.

Droplets smaller than 100 microns may be too fine, which can lead to significant drift and evaporation before they reach the target site, thereby reducing the effectiveness of the pesticide application. Conversely, droplets larger than 400 microns can be too heavy, leading to issues with uniform coverage and potentially causing runoff or excessive deposition on the ground instead of the intended targets. Therefore, using droplets within the 100 to 400 micron range is critical for maximizing the efficiency of aerial applications while minimizing the risks of environmental impact and waste.
