Quinclorac or Triclorphyl

Post by PSU4ME » June 18th, 2019, 6:16 pm

FIL has a solid clover infestation out of no where, will be blanket spraying the lawn, about 6ksqft.

Which of the two do you think will be more effective?

I'm not sure about Triclophyl, which sounds more like an antibiotic maybe (guessing). But Triclopyr, definitely. That said, clover is not really bad, and can co-exist fine with grass until it starts dominating it, at which point you need to do something. I guess that's the situation.

Only thing is, you need to use both enough Triclopyr AND enough water volume. A surfactant, too. I normally use a non-ionic in everything, but recently have tried dish soap with Triclopyr, and I'm planning to try it again because it seemed to work well with it. I added too much, though. And it may take up to 3 apps 10-14 days apart. I was going after violets in the lawn, but also have clover I want to kill in a few places where it's spreading into the main lawn.

Triclopyr, my B, it just rolls off the tongue. I plan to use a surfactant on whichever I use. Was leaning towards quinclorac since I have it unless triclopyr is that much better.

It's that much better. Save the Quinclorac for crabgrass that breaks through...

The amine version does not cost that much, even in small bottles, unless you have a very large area to treat.

Where do you guys buy from? I see some diff things on amazon but all look like they are super strong.

Got a link to something you’d recommend?

Thanks

PSU4ME, there is no answer to that. If you have 2000 sq ft of lawn, a pint of 8% Triclopyr might be the right answer for you. My son's and I share a gallon of 61% Triclopyr for a total of about 4 acres. Both solutions are legitimate. And the strength of the purchased product means little - the 61% product just gets diluted a lot more.

Ok that’s fair, I was seeing the 61% and I was like yeah, that’s rough but I guess I’ll just use less of it. I see the gallons for about $50 or so.

Thanks

Just make sure you get the amine salt for this time of year...it's much safer since temps are over 75 or whatever (just rough temps) now.

Curious what you mean by safer. Is it weaker and gentler on the grass? Why does temp matter?

Or, more chemically speaking, an ester is an organic salt (I've always wondered if Lot's wife was named...er, Esther...)

An amine is an ammonia derivative. One of the hydrogens is knocked and replaced by the new chemical group.

Esthers, because of the salt, shouldn't be used in warm weather. Amines, because of the nitrogen/ammonia, shouldn't be used in hot weather. Usually any bottle warns not to apply at temperatures much over 85.

I feel like October is about as good as it gets in the Fall for weed control. In November in our area, it seems things slow down a bit more and aren't as responsive. April or May seem to work really well, better than a cool October. Some of it depends on your particular herbicides and how they function in certain temps. Different formulas function differently. For example, Triclopyr amine salt doesn't seem to work as well in cold weather (personal observation). But the ester version apparently can be downright dangerous in hot weather (haven't used it yet, so can't comment personally, but I would be careful if I were, because I've read this).
and from Re: Is there a preferred brand of Trichlopyr?:

There actually ARE some differences, but it isn't a brand thing - it's about formulations. Ester formulations are more active, but can have spray drift that affects nearby plants that you don't want to hurt. The amine formulations drift less, but aren't quite as active.
