Super Trimec, Poor Results

[IRRITECH]

Have run 2 tanks of Super in the last few weeks and had very poor results. Rate 1oz/1000 and temps 50-60.

1st time I have run trimec as I have always used Three-Way Ester in the winter. I did not add sticker as it was not labeled (what's that about?)

Ideas???

hmm well how long ago did u spray this....and umm i think it says 64 oz per acre? you should have put sticker on it

[southernsprayguy]

Why not just use straight 2,4-D ester. It's a lot cheaper and knocks out most of the weeds that a 3 way herbicide will. I spot spray with that high dollar stuff. My lawns are always real clean.

Irritech,
could be the weather is still too cool for best action. Fastest and best results occur when the weed is not dormant or slow growing, or mature--but rather when the weed is growing fast. A good rain, 80 degrees and humid conditions are ideal. What kind of weed? Herbicide action depends on the type of weed. Some are tougher than others. And some have different temperatures or seasons when growth is fastest or they otherwise are most susceptible.
Henbit? Wild garlic? Dandelion? Chickweed? Young or mature?

No, high rate is 48oz/acre, yeah sticker makes sense but not labeled (not for trimec plus either). Sprayed weeks ago.

80 deg and I would use regular 2-4-D. 50-60 is fine for ester. Overall weed control was poor.

My guys don't carry it. I use a generic 2-4-D in the summer because of the price. I don't mind paying for the Super as I normally only go through 1 gal per winter

Irritech,
We have used (Vessel) from Prokoz when the temps are consistantly above 70 and never when over 85.
If you experience cooler weather longer, try Coolpower, it is better and still is around 165.00 for 2.5 gallons compared to 78.00 for the other.
Try 3-way Esters next time and you will be safe until the temps get above 80. Then be extremely careful.
Lastly, I use 80/20 sufac with the material. some of those weeds are waxy and the material runs off.

Irritech,
Are you spraying Zoysia and Bermuda's? I hope you aren't hitting the Centi and Augie with this stuff!?

When Super Trimec was sold here, I never had a problem with it not working. It is all in the application. 1-2 gallons/M, flat fan nozzles operated at 40 PSI and 32 oz nonionic surfactant per 100 gallons of spray. I think a lot of issues with something "not working" have to do with application. When a product is going through EPA and university field trial testing, those above parameters are followed.

Irritech,

Overall weed control with just 2,4-D ester is great in the south. 2,4-D Amine is great in the summer. Everyone else may argue about poor results with it but again I have had tremendous success with it. I use Speedzone Southern on the real hard to control broadleaf weeds. Certainty for sedges. Good luck!

[greendoctor]

I will agree with the 2,4-D ester. I use it for broadleaf weed control. A mix of ester, dicamba, Quicksilver and metsulfuron has never failed to kill even hard to control weeds. Cost wise, it is more expensive than 3 Way but more importantly, it kills every weed the first time, with no survivors. I pay more attention to what it costs in terms of a treatment failure rather than a product costing so much per acre. Survivors get resprayed at my expense and clients do not sign a gag clause. I am quite sure they tell people they know whether what I did worked or costed them money and did not work.

I agree with southersprayguy, 24d ester rocks down here in Oklahoma. It is much cheaper (.06/1000) and lower rate than a 3-way product.

Be careful with the Dicamba...it's like a triazine herbicide....it moves in the soil and moves fast. Good way to take out some shrubs or trees. That's why i use straight 2,4-D 99% of the time. Like Varmit said..it's cheap. Cost me about $6.00 an acre at a pound a.i.

Irri,
Super Trimec contains the ester forms of 2,4-D and 2,4-DP, (plus dicamba).

Plain 2,4-D is not enough up here; oxalis, clover, ground ivy, and spurge--all seem to survive it. Our customers want everything gone.

I don't see anything on the label that prohibits the use of a surfactant.

Good grief, I was asking if anyone had had poor results with Super Trimec. I know what it is and how tto use it. I have been spraying since alot of you guys were in Kindergarten.

That's a big 10-4!

Never had a problem with dicamba. When the label says 1/4 lb acre under trees in clay soils and 1/8 lb in sandy. They mean it. The funny thing is, the kinds of weeds I use dicamba on, normally infest lawns growing on clay soils. I will not use it at all if the soil is sandy. Only include it if there is prostrate spurge or oxalis. Did have a problem when I was the license holder for a company and someone under me did a 1 oz per gallon spot spray under trees. 1 oz per gallon is the label rate to kill trees and brush.

I use Speed Zone of Power Zone in the cold. 4-ways/ Expensive but worth it. Could be too cold yet for your weed control to work. Weeds might not be active yet.
