I've never fully understood the surfactant thing. If you read the directions
for the glyphosate products, they say to use a non-ionic surfactant.
But what is dishwashing liquid? From what I could gather, it was impossible
to tell, even for specific brands. What difference does non-ionic vs
non make? IDK. And you'd think in the typical 2.5 gal and smaller jugs
which individuals, small biz, etc would use they would just mix the
surfactant in. Razor does, I think RU does too. But there are lots of
other products that start talking about the damn surfactant instead of just
putting it in. I can understand not putting it in for large quantities,
like a farm would use, so they can use the one of their choice.

I use a brand I get at Tractor Supply. Think it is Big and Tough. You
mix just under 3 oz per gallon. I usually just put in 3 oz. It says it
contains the surfactant and is 41 % gly. It came in about either a half
or full gallon container. Forgot which.

Works well on the poison ivy for me and most other things.
The just need to be sprayed during the normal growing season. The way I
understand it works is that it prevents the plants from absorbing
whatever it is that makes them grow so the starve to death.
Other types of chemicals over feed the plants and they burn their selves
up trying to grow, like too much fertilizer will do.

I am not sure if I killed a 30 foot pine tree with it or not. There was
a pine tree that looks like a big Christmas tree and I sprayed some
weeds and grass that was growing under it. Within about a year the
needles fell off and did not grow back so I cut it down.
I tried not to get any on the tree .
