Glyphosate

[Guest]

what can you put in extra if seeding canola after ?

aim (carfentrazone) or bromoxynil or a combination of both , conquer by fmc

Spraying at less than a liter only tickles the weeds..makes them mad..
Truflex next yr will certainly help.
Or..maybe they are watering down round up..no..that would not happen.

I think you mean next next year

Can someone refer me to a location that stocks bulk liquid AMS? around my parts its not common.

Margin grab by the fuking retail. AMS does NOTHING if you use actual roundup, the surfactants are already in it. Don't buy crap.

Sheesh.

Unless your water is hard.
Or your pH is off.

1. pH is a measure of free hydrogens. Hard water refers to the presence of free cations such as calcium, magnesium and or sodium.

2. Roundup works in a wide range of pH so products like Phix are generally unnecessary. Hence the money grab comment. Retails want to sell farmers addins for glyphosate because margins are so slim on the herbicide.

3. Many farmers put AMS with roundup when it is absolutely not necessary ie, they don't have hard water... expecting an increase in efficacy. AMS helps if you have very hard water or a small number of weed species with elevated calcium levels eg velvet leaf.

4. If you have a reasonably good water source and use proper roundup products with surfactants already included, save your money for a tank mix partner to decrease herbicide resistance.

5. Everything a retail does is to improve margin for themselves. Everything they sell, they upsell to what is best for them profit wise.

Odd story... We are making a new sprayer nurse tank set-up. Bought a trailer and a new 3500 U.S. gallon tank and was going to fill this thing to see how it carries on the trailer and determine tongue weight. Well we don't have our filter and hose set up to suck water from our Department of Highways dug out yet and I was going to go to the town water plant and fill it there(No chemical ever on this set up, so safe to do so but would never do it after the chem handler has been mounted to the trailer or once put into active service). $117.00 to fill the tank with water, LMAO.... to possibly dump it again. Mind you, it "is" Reverse Osmosis water. $1 per 25 Imperial gallons(113 liters).

Here is a good article on glyphosate and AMS. It is very very important you realize roundup in the states is very different than roundup in Canada.

But i'm sure many will claim AMS has a benefit.

Note the levels of very hard water that showed almost no difference with AMS. You can almost stand on 1800 ppm.

BTW, according to the water quality association 180 ppm is considered hard water. This is tested at ten times that level.

For glyphosate, neighbor of ours used to use softened deep well water....and a low gpa water rate....and I don't know what else he put in the tank but did he smoke weeds....even established absinthe.

we use 3/4 liter alone , works good !

[farmaholic]

Last purchase price.... $3.69/liter.

Anyone hear of prices rising?

[seabass]

Agree the softer water with AMS works better. We also use interlock with the Rup.

One retailer mentioned price of Transorb went up around 8% since last year.

Works better then what?

Heres the abstract of the article Twitty linked. Not sure how he could misinterpret the findings of the article so poorly.

"It is well known that ammonium sulphate (AMS) overcomes the antagonistic effect of cations found in hard water on glyphosate activity. In this paper we examine the effect of AMS on glyphosate-trimesium activity when sprayed in deionised water and following hydroponic application to roots of two tolerant broadleaved weeds (Abutilon theophrasti Medik and Convolvulus arvensis L) and one susceptible grass (Sorghum halepense L). The increase in activity from foliar sprays with AMS was greatest on A theophrasti, followed by C arvensis, with no significant improvement on S halepense. Following root treatment of the same weed species, glyphosate-trimesium showed a marked increase in activity against A theophrasti with AMS, with lower levels of enhancement on the other two species.

Any USA farmers on here? Price of glyphosate in the US?
