Persicaria pensylvanica (Pennsylvania smartweed)

Will 2 Quarts per acre of GLY take care of this?

While we’re at it, what about the species below? I was hoping I’d get away with not spraying but I was wrong.

Any potential herbicide that might kill the smartweed but won’t touch the clover? I’m really hesitant to nuke/plant this plot with no rain in the future. This will be my only trip so now or never.

From what I understand (never used) 2-4DB will not harm the clover and specifically has smartweed listed.

Here is another option (again never used)....smartweed listed here as well.

PLEASE talk to some folks who have used these as I have no experience with them....

I wonder if the 24DB has any residual affects. Planning to plant (broadcast) and spray.

I can answer that one. No residual that I’ve experienced using 2 4db and I’ve used it quite a bit in my clover plots and also a little in others.

Good to know, sounds like an option.

Is 2-4DB safe on chicory??? I thought I read it was NOT.

Just mow it.

Just mow it.

I don't think that will have any affect on the smartweed, it's very short.

Ducks and doves love it.
