Saskatchewan Spruce Budworm Protection Program Wraps Up

Spruce budworm protection programs in Saskatchewan wrapped up this week. 20,000 ha were treated in near Hudson Bay in northeastern Saskatchewan, and 700 ha were treated at the Resort Village of Candle Lake and Candle Lake Provincial Park.

The biological pesticide, Bacillus thuringiensis var. kurstaki (Btk), a naturally-occurring soil bacterium, was used between June 5th and June 10th. Btk only kills certain types of caterpillars, including budworm.

Here are some photos from June 7th, the morning of the first Btk application at Candle Lake.
