Some of these locations may be very difficult to access from the ground. Aerial application of Btk is the most effective and cost-efficient method of applying Btk over a large area and reach foliage located in poorly accessible locations. Furthermore, and most importantly, over 30 years of aerial application on human populations have revealed no short or long-term adverse effects to human or environmental health. For more information on Btk, go the Btk Facts page. Undiluted Foray 48B is transferred directly from its shipping container into the holding tanks of the spray aircraft.
Aircraft then fly to the site and apply the insecticide.
Droplet size is critical to maximize the coverage and spread of the product through the canopies of trees. The aircraft go through a rigorous calibration process using the product before being applied on the target area. This calibration ensures that the target area receives the desired droplet size and dispersal pattern. This height allows the best dispersal of the droplets and minimizes drift. Aircraft noise during the early morning application window will be noticeable but the disturbance should be limited to a short time.
