What is the primary purpose of a cone nozzle in pesticide application?

The primary purpose of a cone nozzle in pesticide application is to apply pesticides to dense foliage. Cone nozzles produce a conical spray pattern, which is particularly effective for targeting plants with thick canopies or dense vegetation. This design allows for better penetration of the pesticide into the foliage, ensuring that the solution reaches the undersides of leaves and other hard-to-reach areas where pests or diseases may be hiding. Dense foliage can obstruct the spray from conventional flat fan nozzles, making cone nozzles advantageous in these situations.

Other options may seem relevant but do not capture the unique functionality of cone nozzles as effectively. While herbicides can certainly be applied using various types of nozzles, they are not specifically the focus of cone nozzles. The notion of achieving even spray coverage is important in pesticide application; however, cone nozzles are primarily designed for their ability to distribute the spray into thin and layered parts of bushy or thickly vegetated areas. Maintaining high pressure is also a factor in nozzle operation but is not exclusive to or the primary role of cone nozzles, as high pressure is required for many types of spray nozzles to operate efficiently.
