The members of this genus are known as teasel, teazel or teazle. The genus includes about 15 species of tall herbaceous biennial plants growing to 1–2.5 metres tall. Teaselweedcontrol usually requires a multi-pronged approach.The best way to gain teaselweedcontrol is to remove flowering stalks by hand before seeds are mature. With teasel being a biennial plant, control e orts will take at least two years and possibly longer, depending on the amount of teasel seed in the seed bank. This project will use insects for biological control of three weeds that are invasive in Illinois and the Midwest -- garlic mustard, teasel and leafy spurge. “Infestation” is the term for what teasels are doing in Missouri. Learn to identify these thistlelike plants, and help to control the weedy spread of these tough, prickly invaders. Common TeaselControl. Tools for Teasel Removal.

Discover the best time to apply herbicides for effective control of invasive cutleaf teasel. Study examines impact on surrounding vegetation and seed production. Teasel prefers mesic habitats that are open and sunny, but is also found on drier sites. Teasel plants can produce 3,000 seeds per plant with up to 80% of the seeds germinating.
