How the Heck do you kill canada thistle? I've tried Tordon, Mecamine D, and old mixed 2-stroke gas on these sons-a-guns, and the only thing that touches it is the gas. You have to use a fair amount of it on the weeds though for it to really do it's job. I'd rather not have to continue to use gas on a lawn, but I can't for the life of me kill these stinking weeds They're taking over my backyard, and I'd like to let my young kids run around out there without getting pricked. Any fool-proof methods that won't kill the grass along with the thistle?

The key principle to Canada thistle control is to stress the plant and force it to use stored root nutrients. Canada thistle can recover from almost any stress, including control attempts, because of root nutrient stores. Therefore, returning infested land to a productive state occurs only over time. Success requires a sound management plan implemented over several years. Mow then spray, once it starts coming back up. Table 1. Herbicide to control Canada thistle in pasures, rangeland, natural and noncrop areas. Herbicide Rate (Product/A) Application timing Comments Tordon 1 quart Anytime when weeds are rapidly growing Fall applications consistent results; may need re-treatment 1 to 2 years Milestone 5 to 7 fl oz Spring at pre-flower-bud growth stage; or fall Use higher rate for older or dense stands; Milestone may be used to edge of ponds or streams; may need re-treatment 1 to 2 years Transline 0.67 to 1.33 pints Spring after all shoots have emerged, rosette to early bud growth stages; or fall Apply 1 pint/A or more in fall; may need re-treatment 1 to 3 years Perspective 5.5 oz Spring rosette to flower bud growth stage; or fall Use with a non-ionic surfactant at 0.25% v/v Telar 1 oz Spring bolting to bud growth stages; or fall Fall applications most consistent results; essential to use non-ionic surfactant at 0.25% v/v; may need retreatment 1 to 2 years Banvel,Vanquish, or Clarity (dicamba)
2 quarts Spring rosette growth stage; or fall Fall applications most consistent results; may need re-treatment 2 to 4 years

Grazon Next kills it you just need to give it a bath, I drive real slow when spraying around it.
Was born in a Big City Will die in the Country OK with that!

This is what I use. Spring and fall. Might take a couple years to get them under control if you got a bunch. doubt there's anything better i use the 65% active ingredient spray when they're small and check your neighbors yard to see if thats where they came from

Canada Thistle spreads on rhizomes so wouldn't recommend the hoe method. You just turn one plant into 5. Grazon next does a pretty decent job. Spray prebloom or fall 4-6 weeks prior to frost
