Wide-swath Spray Application in Ornamental Nurseries with Cannon Air Jet Sprayer
- Abstract::
- Pesticide spray applications in nurseries are usually implemented in the very early morning to avoid chemical exposures to regular workers and to prevent potential drift to nearby residential areas. Conventional sprayers cannot efficiently apply pesticides to many container ornamental crops due to the special planting circumstance. A cannon air jet sprayer was investigated in an effort to use optimal spray techniques to effectively control pest insects or diseases for container ornamental crops. Air velocity, spray deposition, spray coverage and spray spot density on artificial targets inside and outside hydrangea plants at two heights across the spray swath were evaluated and correlated. Treatments included three flow rates, three travel speeds, and two different nozzle settings. Under the calm weather conditions, the cannon air jet sprayer could provide fairly uniform spray distributions across the 24 m spray swath.
