Aerial spraying for spruce budworm slated for area watersheds

Western spruce budworm treatment planned for regional areas in early June

The Ministry of Forests, Lands and Natural Resource  Operations plans to aerially treat up to 28,000 hectares of Douglas fir  forest in the Okanagan to reduce populations of western spruce budworm.

The proposed treatment areas include the Ellis- Carmi forest service road, Clark Creek, Inkameep, Madden Creek,  Naramata Bench, Okanagan Falls, Naramata Mountain, Shingle Creek, and Sheep Creek. The pest management plan and maps of  treatment areas can be viewed at the Thompson Okanagan Region Forest  Health Program office at 441 Columbia Street in Kamloops (or online at :

The biological agent Foray 48B will be applied by helicopter on or  about June 10-15, 2012, weather permitting.

Foray 48B is a biological insecticide that is widely used in B.C. and  is registered with the Organic Materials Review Institute. The active  ingredient in Foray 48B is the naturally occurring bacterium Bacillus  thuringiensis var. kurstaki (Btk). This spray only affects moth and  butterfly larvae and can be used safely around humans and other animals. Birds, household pets, fish and beneficial insects (including  honey bees) are not affected.

The western spruce budworm is an insect that is native to B.C. and the  Pacific Northwest. In its larval stage, it defoliates Douglas fir, true  firs, spruce and larch trees. A budworm outbreak has the potential to  seriously harm or kill trees over large areas.
