Euge I had Great results this year from a product I got from the county weed n pest.
It really targets canada thistle and wipes it out nicely...it is called Redeem. There are some
constraints you will want to study up on....like deadly to conifer trees....soil residules etc...
Your thistle needs to be up 3-4 pairs of leaves for exposure to be effective.
Generally the best time of the year here, is in the fall because that is when the plant
tries to pull nutrients into the root for the winter. Pulls the poison in with that mechanism.
I apply it to each thistle (spot spray)using a plastic quart hand held spray pump bottle. Where it contacts
surrounding foilage ....yes grass....it affects it too.
Anyone klnow how to effectively kill field bind weed?
