Description
Biennial thistles produce seedlings during the summer and fall. Plants overwinter as rosettes and produce a flower stalk the next spring, seed, and die. Musk and plummeless are the most serious of the biennials. They produce a heavy seed crop and seedling vigor is very good. Treatments suggested have provided over 90% control into the next season and have reduced seedling emergence considerably during the next year.
