Canada thistle is a large irritant and can become a serious weed problem
if left to thrive. As an invasive plant the traditional control methods of
spraying and hand slashing can be environmentally damaging and hugely time
consuming. Farms and Ranches that operate organically or with environmental
farm plans will benefit greatly from studying the longer term effectiveness of
This project will monitor the effectiveness of the stem mining weevil
(Hadroplontus litura) at eradicating thistle patches over a 3-5 year period.
Weevils have been shown to be an effective control method in areas of Alberta. This
project will determine if they can be used as a long term solution, and if they
can weather the climates of the Peace Region in BC.
