Surfactant with round up

It say you can use it but not necisary. Will it make a big difference ? I'm spraying with 15 gallon sprayer on a four wheeler

I haven't done any comparisons or experiments, but I just add Dawn to my sprayer.

only thing with dawn is it will foam up kinda bad in your sprayer when sloshed around. could take up room inside sprayer

Same here. Good old soap. I got enough other stuff to worry about.

Add liquid AMS. It'll help more than anything.

I've been using the spray grade powder for several years. I think I get (6) 50 gallon tanks out of a 51lb bag. What does the liquid sell for and what's the mix ratio?

My favorite was Phase II from Riverside. Local Co-op doesn't have it anymore but has a similar product called Class Act. Much better than dish soap in my opinion.

I usually just buy a jug of surfactant from Tractor Supply. When spraying cogon grass and other stuff it just sticks better. I sprayed some bamboo fishing canes the other day and I know it won't stick to that stuff without a surfactant.

I've been using gly for over 20 years and have never added a surfactant and I've always gotten a good kill. I do use one when I add 2,4,d to the mix.

most of the generic roundup sold has a surfactant already in it

Unless you're spraying some kind of seriously tough to kill plant then I don't see where what you get from the co-op needs anything added. The generic I get is called Cornerstone Plus. It's my understanding that the "Plus" means plus surfactant. Never had an issue with getting good kills on your everyday weeds and grasses.

Yep. Stuff I buy at TSC has it already in it.

Doesn't mean adding will hurt.

Doesn't mean adding more will help either. I prefer to go by the labels. If the label doesn't tell me to add any, I'm not wasting my money by adding it.

I add some class act or synergy or something to everything I spray. Most are like $40 for 2.5 gal and 1 pint per 100 gal. It's not like it cost a fortune. Chemical is the cheap part of the equation to me
