glyphosate prices

[DogPatch]

I was told that the upper end products like Transorb, Vantage Plus and Touchdown all have a guarantee rainfastness, and thistle control in it. With all the freaky weather we have had, that something to think about another time.

The Generics are still cheaper, but I am reluctant too about the old formulation varieties. They are only as good as the OLD Roundups for the most part. Why would anyone want a 360g/L when a more concentrated one is available?

One of you mentioned 1.5L equivalent on your lentils. Shouldn't we be worried about possible seed contamination? Thats far more than whats registered anywhere. Wouldn't want a boat-load condemned like has happened with Malation, lindane or stuff like it.

Plus I don't think we can save seed if we use the glyphos?

Dogpatch I still remember when I did my first pre harvest with the regular roundup and planted peas the next year. I think I cleaned the field of thistles for something like 8 years with that one application. Then the new formulations came out and never again got such a good kill. Clearout also kicks ass in my opinion.

There are generics with 450 grams. I would not be too worried, if you apply 1 L of glyphosate it shows up, 1.5 L will also show up and i do not think should be a concern, but you do raise a point i never thought about.

Concentration of glyphosate does not affect control. How could using less of a more concentrated product increase control?

I will spray one quarter with Reglone for seed.

If a guy can buy generic at $2.55/L who cares if you have a guarantee. The reason the give a better guarantee on rainfast or frost in the spring is offset by the higher cost and numerical guess of the acres that are claimed against. We really need someone to do some inpendent testing of all these glyphosates, similar to co-op trials to seperate the facts from the fiction.

clearout is smokeing hot esp. this spring . using 3/4 to .9 liter burnoff.
i feel sorry for the rock piles.
if i had better water supply , (use well water) they would all work fine.
have used some cheap ones and several 540 gram versions . i think a lot of the 540 gram and the super cheap do not have enough surfactant to tame my water.

[SASKFARMER3]

We have been putting glyphos on for years and the clearout 41 and generics work just as good as the expensive ones. Tell your self the expensive ones work because they cost more is purely ridiculous. But what makes sense is spraying at proper time 9 to 5. Dew, if its raining 10 miles away quit. etc etc. Reglone pulses for seed spray the rest wont hurt germ. but for some reason pulses it does hurt.

The only difference between them all is the surfactants and additives. The glyphosate is all the same and to receive registration the glyphosate salt needs to be equivalent and the weight of the active ingredient guaranteed.

In most cases using more cheap glyhosate is better then the more expensive with additives. Add a group 2 like sulfons to a cheap glyphosate and it is much better again.

It isnt all the same - there are different kinds of salt. Try mixing TD and Transorb like i did last year (I switched over and didnt clean out the tank) and tell me its the same. A wasted tank of chemical and a day flushing the hell out of the sprayer is what I got. If its all the same that wont happen. You are wrong.

[ado089]

After years of custom spraying, retail and farming I've noticed that the high concentration products are harder on the crop and less effective on the weeds. In my opinion there is not enough surfactant in them to when spraying at 1/2 eql and/or more than 5gal/ac to condition the water. This year I used Polaris (Dupont's 360g/l) and got the best kill I've seen in a long time. 1/2L/ac looked like a full litre, it even got the foxtail barley around the sloughs. Nufarm now has 15 minute rainfast on Credit 45 and my rep told me today that Nuglo comes out of the same tap.

Apparently the Amerikins are running ita some issues. WEED RESISTANCE TO GLYPHOSATE..... Please tell me its not true, cause Comedians are dumber than them, sooos the problem will likely be here sooner than later. With all this cheap product available, likely sooner than later, then what, then what, back to integrated weed management. Whoa is me, whoa is me. Clubrot, now Monsanto rot, what next??? Rot rot me guesses!!!

[wd9]

sjc, work at the university of Illinois and purdue university found neglible differences between the salt formulations and aditive differences.

Glyphosate is an acid and is the same regardless of the salt formulation you get in the jug.

You have the parent acid (glyphosate) plus isopropylamine or ammonium or potassium etc salt for mixing and handling plus the surfactants.

Weathermax is potassium and touchdown is diammonium and the original is isopropylamine.

But the glyphosate acid is all the same.

[wd9]

Oh and don't mix different salts as they have dramatically different molecular weights and ability to hold an acid.

[Francksaskfarmer]

I was told that adding some 28-0-0 liquid fert helps to get a good kill.
Does it act as a surfactant? If so how much should be added in proportion?

[mustardman]

Using ammonium sulfate helps with hard well water. At 5 gpa spray rates I use 0.5 % w/v or if using 10 gal/acre for preharvest will up ams to 1%

[mustardman]

Just make sure you add ams first so glyphos doesn't get "tied up " with the hard water
