glyphosate prices

[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.

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

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?

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%

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