Glyphosate

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

Anyone hear of prices rising?

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?

Seen an ad for a new herbicide yesterday; Roundup for Lawns. If that doesn't make you wonder about the strength of Roundup!

Wondered if it was a late April fools day joke but went on line and it is for real.

Take a look at the active ingredients - that explains why you can use in lawns.

If you actually read the article Lentil, that study is used for the basis of this study. and the conclusion was little to no benefit under most conditions using a real product like transorb etc with all the proper surfactants. Notice the colorful charts?

Oh sure, if you buy crap glyphosate without surfactants - cuz you got a good deal on it - then perhaps, although it wasn't specifically tested so can't comment for sure, but that is just stupid considering the price of the good stuff vs adding snake oils.

What are the rules....I thought chem cos don't have to list the type and quantity of surfactants in their glyphosate products....only the active ingredients and their quantities.

I did note there is no glyphosate in Roundup for Lawns. However in the public's mind "Roundup" is synonymous with glyphosate. Re-read this thread to see how many times Roundup is used instead of glyphosate. Furthermore, there will be consumers who apply glyphosate Roundup to their lawns instead of Roundup for Lawns believing any Roundup is now safe on lawns (or simply making a mistake and purchasing Roundup instead of Roundup for Lawns). The resulting backlash by angry consumers will be another nail in glyphosate's coffin.

Furthermore if "Roundup" no longer has to contain glyphosate, even farmers best start reading the a.i. in all pesticides.

Correct. Only the active ingredient, concentration, and the chemical form.

3.85% MCPA, dimethylamine salt, 1.80% Quinclorac, 0.43% Dicamba, dimethylamine salt, 0.22% Sulfentrazone

Low enough concentrations to practically mix drinks with.
