What kind of sprayer would typically be used for tree canopies?

An air-blast sprayer is typically used for treating tree canopies because it effectively delivers pesticides to the upper parts of trees, where pests and diseases often reside. This type of sprayer uses a high-velocity air stream to propel droplets of the pesticide solution into the tree canopy, ensuring that the foliage receives adequate coverage. The design of air-blast sprayers allows for penetration into dense foliage, making them ideal for large trees and crops with tall canopies.

Ground sprayers may not reach upper branches effectively, while handheld sprayers are generally not suitable for large areas or high canopies due to their limited range and coverage. A drip irrigation system, while useful for delivering water and some nutrients directly to plant roots, is not designed for applying pesticides and would not be effective for this purpose. Thus, the choice of an air-blast sprayer stands out for its efficiency in treating tree canopies.
