I have added two articles at the end of the Spruce Budworm and Spray Aircraft in the New Brunswick Context: 1950’s to 1980’s page, both of which that came from the Forest Protection Limited files:
1) Progression towards smaller spray blocks in New Brunswick (H.J. Irving 1985), and
2) Early TBM use in N.B. by Forest Protection Limited (Don Henry 2008).
Stay tune for many more updates coming soon and in the new year.
