So, a product like RoundUp Ultra that contains surfactant will be enhanced by addition of ammonium sulfate if mixed with hard water.

What can I use as a surfactant for Roundup?

What time of day is best to spray Roundup?

Highlights of findings

But the project's results show the early morning timing is often coming at a cost for herbicide efficacy.” In both the burndown and in-crop studies, the most effective timing was usually midday, followed by midnight.

What happens if you mix vinegar with Roundup?

Probably not a good idea. Roundup is only slowly taken up through the leaves and is easily washed off. There is a steady trade in surfactants and oils that are supposed to increase its speed of uptake and give better results. Since vinegar is likely to scorch the leaf, IMHO it would slow down the uptake of Roundup.

Will soap work as a surfactant?

Each molecule has a hydrophilic head that bonds with water and a hydrophilic tail that bonds with oil and fat and rejects water.

What can I use as a natural surfactant?

Why is my Roundup not working?

If the supply water hasn't been treated and glyphosate is exposed to hard water in the tank, glyphosate is dead before it even hits the sprayer, Brown says. “You need to pre-treat your water in your supply tank with AMS or another softening agent,” Brown says.

Does Roundup ever leave the soil?

It can persist in soil for up to 6 months depending on the climate and the type of soil it is in. Glyphosate is broken down by bacteria in the soil. Glyphosate is not likely to get into groundwater because it binds tightly to soil. In one study, half the glyphosate in dead leaves broke down in 8 or 9 days.
