2,4-D vs. 3-AI product in triangle approach?

[Green]

For level one of the triangle approach, why would you pick plain 2,4-D versus a 3-AI mix that contains 2,4-D? Assume both contain the amine formulation. Are there certain situations where you'd rather have the plain 2,4-D without the MCPP, etc.?

I've posted the following a couple times before. Doesn't answer your direct question, but it fits the discussion.
2,4-D and Mecoprop-p and Dicamba – Oh My!

I don't think you would choose a 2,4-D product over a three-way. But a 2,4-D product is acceptable, and "perfection is the enemy of good" -- the very point of the Triangle Approach is to get out of the analysis-paralysis mode and get the weed-killing job underway.

Thanks both of you. I'll stick with the combination herbicide.

I use a straight 2,4-D product, as I have trees bordering and throughout my lawn and dicamba has been shown to have a markedly greater tendency to translocate into the tree via the roots. A google search for dicamba and trees will show many studies to this effect.

Good point. I saw that last week when I was searching on this topic. But thank you for the reminder...I had already forgotten about it!

I wonder if there are many ready-made 2,4-D/MCPP combos that omit the Dicamba...that are somewhat readily available and cost effective.

One can't easily search for "2,4-D" online (including this site) because of the numbers and hyphen. Google is a bit easier, but it still needs to go in quotes at times. I'm starting to look for a two-AI product that omits the dicamba.

It does seem there's a good amount of articles and whatnot mentioning wind drift being an issue with Dicamba as well. It seems like the weakest link in the 3-AI product.

Then again, do I really need the MCPP either? It seems primarily geared toward Chickweed and Clover. Isn't that what we have Triclopyr for?

I think these are good questions to ask.

It googles so much better if you call it 2,4-Dichlorophenoxyacetic Acid. But that's only if you can remember how to spell it.

I can remember it...I've taken organic 1 and 2 and biochem 1 (still don't know that much chemistry, after all that though...just a few basic courses). But the real question is, will it break "the google"?
