During the budworm control operation in Maine during the 1975, spray was applied to TBM, PV-2, C-46, and Constellation aircraft. At that time no attempt except for estimation of gross appearances of the spray blocks, was made to compare the results in areas treated by the various types of aircraft.
After the egg mass survey was completed, the question was raised by the U.S. Forest Service as to the relative effectiveness of the Constellations Vs. the TBM's and the PV-2's ie. conventional aircraft.
The surveys and analysis done, and the results of the work to determine the relative effectiveness of the different aircraft are contained herein.
