2 AgCat
18 Cessna
0 Stearmans

Ontario

3 Stearman sprayed fenitrothion on 21,000 acres June 6-18 1969 in the Burchell Lake area and 1 Stearman sprayed 5000 acres in the French Lake area of northwestern Ontario. All aircraft were contracted from General Airspray of St. Thomas, Ontario [Table 4, Howse and Sippell in Prebble 1975]

These were probably:
#71 CF-FBD
#76 CF-VOB
#77 CF-FRZ

1970

A letter from Crown Assets Disposal Corporation, Ottawa (November 28, 1969) stated that 20 Stearmans were left in Canada, “all very old”.

New Brunswick

Aircraft
1 Stearman

FPL provided one Stearman sprayer to the C.C.R.I. (Chemical Control Research Institute, Environment Canada) testing program located at the Scoudouc Airport. These trials continued in 1971.

Ontario

Aircraft
3 Stearmans

Stearmans organized by tail/project number – 1970

Bradley Air Services Ltd., Carp (Ottawa), Ontario [Why 4 listed?]

#71 CF-FBD
#72 CF-DZC
#73 CF-DQP
#74 CF-IBA?

Two Stearman sprayed fenitrothion on 11,000 acres June 13-26 1970 in three small areas in northwestern Ontario. Also two Stearman on floats June 13-15 in northeastern Ontario and one on floats in southeastern Ontario May 29 and June 7. All Stearman were provided by General Airspray of St. Thomas, Ontario, and used boom and nozzle. [Howse and Sippell in Prebble 1975]

These were probably:
#71 CF-FBD
#76 CF-VOB
#77 CF-FRZ

Quebec

FPL employed three Stearman guided by a leading Cessna to spray fenitrothion in Quebec north of Ottawa-Hull, in the Gatineau Park and the lower Gatineau areas as far north as Low. They were deployed from Carp Airport, which is located near Ottawa-Hull. This was the last use of Stearman in Quebec. “Afterward the sprayers moved to Mont Laurier and from a local field sprayed some 2,500 acres of jackpine infested with Jackpine budworm.” [Forest Spraying Operations – 1970. Forest Protection Limited. B.W. Flieger, October 26, 1970; Blais et al. in Prebble 1975].

1971

New Brunswick

Aircraft
1 Stearman

FPL again provided one Stearman sprayer to the C.C.R.I. (Chemical Control Research Institute, Environment Canada) testing program. These trials were undertaken in a mixed spruce-fir-hardwood stand in Westmorland County near Scoudouc, New Brunswick. Application of the sprays was made by using a Stearman aircraft (CF-EQS) [Wheeler-Northland Airlines] equipped with four AU-3000 Mlcronair units. [Randall et al. 1971].

Ontario

Aircraft
3 Stearmans

Small areas in northwestern Ontario were sprayed May 21 to June 19 by General Airspray of St. Thomas, Ontario, using three Stearmans equipped with boom and nozzle. Also one Stearman June 13-19 in northeastern Ontario [Howse and Sippell in Prebble 1975]. This Stearman aircraft was on floats and arrived in Chapleau on June 13/71 and spraying started that evening. [Howse et al. 1971]

These were probably:
#71 CF-FBD
#76 CF-VOB
#77 CF-FRZ

1972

New Brunswick

Aircraft
2 Stearmans
2 Agcats

FPL conducted an experimental spray program against adult spruce budworm moths on the Tobique River drainage. Spraying was conducted out of Dunphy Airstrip using a formation of four Stearmans eqipped with Micronair spinning cage nozzles. However, two of these, CF-UOF #51 and CF-UOG #52, were actually AgCats. The total of four Stearmans probably comes from the listing of all four aircraft without distinguishing them. This also occurred in 1973.

Ontario

Aircraft:
3 Stearman

Small areas in southeastern Ontario were sprayed May 26 to June 5 by General Airspray of St. Thomas, Ontario, using a Stearman equipped with Micronairs. [Howse and Sippell 1975 in Prebble]

These were probably:
#71 CF-FBD
#76 CF-VOB
#77 CF-FRZ

1973

New Brunswick

Aircraft:
2 Stearmans
2 AgCats

FPL again conducted an experimental spray program against adult spruce budworm moths on the Tobique River drainage. Spraying was conducted out of Dunphy Airstrip using a formation of “four” Stearmans. However, as stated in 1972, two of these, CF-UOF #51 and CF-UOG #52, were actually AgCats. The total of four Stearmans comes from the listing of all four aircraft without distinguishing them on a handwritten list in the FPL files.

Aircraft:

Small areas in northeastern Ontario were sprayed June 9-21 by a Stearman and an AgCat from by General Airspray of St. Thomas, Ontario, and one Stearman in southeastern Ontario May 24 to June 4 by Midair Canada using one Stearman and a Cessna AgWagon equipped with Micronairs.
