Triclopyr per Acre

I ordered some 61% Triclopyr. I can't find how much to use per 1K sf or per acre. Can someone help me out on the amount for my northern mix grass?

Also, I applied speed zone at label rate today. Is there any reason I need to wait to apply Triclopyr? I have some nasty violet I am trying to dispense.

I have 61.6% triclopyr and the bottle I have the label is not clear at all with amount to use. I used right around 3/4 fl oz per k on my neighbors no mix lawn with a 1 gallon water carrier. I was dealing with clover and that amount worked well. I noticed a slight yellowing of the surrounding grass after the second application but it only lasted a week or so. You could go lower than 3/4 fl oz and I think it would work fine. Especially being it's getting into summer a lower rate might be a better idea. 3/8 - 3/4 fl oz per k is the range you want to target.

The label should have all the info that you need. That is a very concentrated product, so I would reread the label as many times as necessary and post a question on this thread, if you want to double check the math. You can always post a photo of the label for reference.
Rate is not on the label unless equivalent to fruit trees

When I purchased the 61.6% I did the math comparing it to the CCO I had been using. With CCO I would use 2 ounces per gallon if the temps were 80 or less and drop to 1 ounce per gallon (label rate) if the temps were above 80. With the 61.6% Triclopyr 4 that works out to 7cc's per gallon and 3.5cc's per gallon respectively. I've used these rates for spot spraying the last 2 years along with an NIS and it has had no ill effects on my TTTF. For wild violets you will need to make multiple apps 10 to 14 days apart (3 apps should get the majority). You will have to be persistent with the violets as they will come back over the next several years although it should be less each year. At these rates clover might take a second app and most other broad leafs will be gone after the first app.

Thanks! It did not even don on me to read the label!
