I'm a part time Northern Colorado resident fighting an ongoing battle with Canada thistle and musk thistle. Based on my usual schedule of visits, I've settled on a regimen of mechanical control (cutting down everything I can in the summertime) and chemical control (spraying in the fall).
For some number of years, I've been using Curtail with limited success. My big jug of concentrate is now empty, so I've revisited online recommendations before buying more.
It seems like the top rated stuff available to consumers is now Milestone.
Does anyone on this list have experience with Milestone? Alternate recommendations? Sources in Northern Colorado (Front Range communities from, say, Denver to the Wyoming border)?
Thanks in advance,
