Overdrive controls more than 90 annual broadleaf weeds, including kochia, Russian thistle, marestail, sowthistle and prostrate spurge, as well as more than 50 biennial and perennial weeds, such as musk thistle, yellow starthistle, Canada thistle, western ragweed, bull thistle

, with blue and pink flowers the size of eggs nodding on thin, spine-covered stalks.
