who using stright 2-4d?

[ant]

with all the dandelions out there, i think the cost is low..

[LawnTamer]

In March/early April I use straight 2-4-d ester lv4 It works better at low temps and cleans up dandilions real fast, once other weeds start popping up and daytime temps rise I switch to 3-way.

i think this yr. i am giving it a shot..

[Duekster]

MMM, what is considered a low temp?

[txgrassguy]

Duekster, any ester based herbicide has a very high volatility rate above about 78*-80*F.
So right now is a good time to apply and I have successfully applied 2,4-D at 34*F several times. I didn't like to spray at those lower temps but circumstances at the course dictated the time of the application.
I actually got reasonable control as well but I froze my butt on that freaking Cushman sprayer though.

That brings back memories. :)

With all the COLD weather we are having now I think I'm going to skip on into the TSC or Orchelns and pick up a gallon of 24D Ester 4L myself... I can't even use the 3 way or Momentum I have in the garage due to the cold, and the weeds need to be taken care of now, not in a few weeks.

I stopped using the expensive 3 way mixes years ago. I use a low volatility 2, 4-D year round. I would look at getting it in the 6lb formulation rather than the 4lb. The cost difference is negligible but you can use 30% less with the 6lb so it is a whole lot cheaper. Most of the cost is in shipping.

i mix mine with water

sorry guys: you know what i ment..lol

Thanks Friend.

I hear so much. I some times feel paralyized from the info I get.

I just dropped a $ or so picking up some Primo to work into my Lawn program. I also bought a new gun. Now I find out a huge textile company is selling fertilizers. WTF?

I sure hope the Primo pays off.

I don't really think of 80F" as a low temp but the info was a great help.

I sure hope you are charging the customers for the primo, I just don't understand why people use this on residential lawns in this area

I am using it on lawns I treat and Mow. I know it is high. :cry:

Without jacking this thread, why go with primo?
There are other growth regulators on the market, for instance embark, which is just as effective as primo and a whole lot cheaper.
Lawn Dawg, the use of a growth regulator will allow one to maintain much deeper roots on the turf with little or no impact on leaf development.
Very important during times of drought/heat stress. You have to handle this type of program carefully as granular fertilization with a growth regulator=trouble. To use a granular fert with a growth regulator requires a much smaller mesh size, basically greens grade fert otherwise foliar dessication and damage will occur from the larger prill sized granular fert.

I do liquid app's. I will look into embark.

We have a lot of stressed lawn after the drought the last two years. I want to get them into condition, nice and green but don't want a lot of top growth since we also mow them.

It would be nice to also cut them a little lower because they look better. That is hard to do with Bermuda when you mow weekly.

Primo is cheaper when you look at the appication rate compared to EmBark.

[nik]

Duekster, any ester based herbicide has a very high volatility rate above about 78*-80*F. That temperature range will be for the air immediately above the application surface. If the area is next to a building, cement wall, adjacent to asphalt, lots of rocks, etc., the air in that microclimate can be much warmer than the "official" temp. Also, a fence, hedgrow, brushline, thick stand of trees or something that creates a pocket of still air will
cause a mini-inversion. You could be out spraying on a nice 70 degree day and it could be 83 right around where you are applying. 2,4-D esters will more often than not start volatilizing.

Commercial vineyards are real popular in the NW now. Started by folks with money who also have nice lawns. You can ruin a good sized chunk of grapes with any phenoxy used in the right (make that wrong) conditions. Those volatiles can travel a long ways. you could whck plants at the house next door and the one next to that and even further.

2,4-D is a time honored product, just be aware of what it can do if your not real careful.

[Duekster]

I looked at the label and it appeared to have an app rate about 4 times higher and in my experiance this rarely means a dollars savings.

I sold water treatment chemicals for over 9 years including many pesticides. This also seems to hold true with lawn application products.

I have not priced it out right yet.

Awesome good info.

[Grassworks Inc.]

Think Cool Power, Ant. Switch to Escalade, Chaser Ultra 3, or Battleship 3 when it gets warmer. The miniscule savings aren't worth the improved control you'll get with a better herbicide. Those re-treats cost $$.

Hi gang, I have a question about how much to use. I too picked up a large jug of 2-4-D LV4 from TSC and need to spray the weeds in a large field. It says to apply at 1pt/acre. It gives no indication of how much water to mix for that solution. I'll be using either a 15 or 25 gal pull behind with I believe about 1gal/min app rate. TIA

Embark will turn your grass brown, it'll look as if it is going through summer drought stress. Primo will not turn your grass brown. Primo is far and away, a far superior growth regulator when compared to Embark.

I don't even know why Embark is still being made. PGR's have come a looooong way since Embark came onto the market.

TTT, anyone with input on this???

You need to figure out how many gallons per acre you will spray with your pull behind and mix at that rate even if you are spot treating. mark off 1000 sq ft and spray it, check and see how many gallons you sprayed. you will probably need about 1.5 oz of 24d per 1k in the finished mix.

Great, thanks for the input!!! I'll see what I can find out on the sprayer.

[thor20003]

I generally put in 1 pint per 25 gallons. This seems to cover about a half acre. My mixing instructions say to use 2 pints per acre on turf grass so I should be about right. If yours says 1 pint per acre, then I would start with a half pint/25 gallon tank and go from there.

[cantoo]

We used to use a lot of 2,4D until we got tired of customers complaining about the strong smell. Much stronger than PAR111.
