I would hesitate.

That's good enough for me! No deal. I'll wait at least two weeks then. It's not worth a risk at all. It's at the back of 3 acres where I park the woods mow'n machine.

 

Not exactly the same but, I applied SZ and TCP together last year... BAD IDEA

 

Run the triclopyr low rate. That combo is essentially TZone (sub sulfentrazone for carfentrazone) it works well.

did you lose lawn?? or did it just discolor?

how confident are you? do you have first hand experience?

 

The high rate of TZone works out to 0.12 oz/M of triclopyr (active ingredient). So whatever concentration of tryclopyr you have I would run whatever amount gives you 0.12 oz/M. If the conditions were such that you were not worried about speedzone, I would not be worried about the tryclopyr being added. I roll my own versions of pre made mixes like speedzone and spike them with additional kickers all the time to save money on applications for clients. Main thing is do what you are comfortable with. Waiting 14 days to give you peace of mind may be worth it to you.

 

I wouldn't have expected an issue. I mix triclopyr with 3 way all the time. What happens when mixed with speedzone?

 

I mixed 1/4 speed zone and the rest weed b gone cco and it worked very good on violets and clover. I did 2 apps ten days apart, had no damage to good grass.

I "lost" lawn for the entire summer basically... but it being KBG, it bounced back. I would take advice from the other posters in this thread and go with lower than labeled rate. This time around, I'm going to apply just TCP a month apart from other herbs.
