Cariboo Region
The Cariboo program treated 47,998 hectares (Table 1; Figures 1, 2), using 115,195 litres of B.t.k. The program
required 11 days to complete, between June 25 th and July 7 th , 2012 (Table 4). Production ranged from 2,075
hectares to 9,008 hectares per day. Start-up and completion of the Cariboo program was impeded by cool, wet
weather throughout June. All treatments targeted 4 th instar larvae and full bud flush.
The 2012 aerial application in the Cariboo Region was completed by Conair, using two AT-802F Air Tractors.
The project was a collaborative effort between Region and District staff, the Provincial Air Tanker Centre, Conair
and several forest health consultants. The B.t.k. was delivered to the Cariboo in tankers, where it was transferred
to several 2,500 US gallon storage tanks located at the Williams Lake and 108 Mile airports, which were used as
staging sites for the program.
