When is Brushkiller 875 rainfast?

[millstreaminn]

I sprayed all the fences with Brushkiller 875 yesterday afternoon. Weather forecast was for no rain until today. Anyhow, it rained on what I sprayed after 6 hours. Wonder how long it is 'till these brush killers are rainfast? I looked online to no avail. This is the makeup of what I sprayed. Thanks

I wouldn’t worry about the 2,4D part of it. I’m not sure about the other ingredients. I looked online as well and couldn’t find anything, but I suspect it’ll be alright.
Here’s a list I found online. It only lists brand names, but I bet some of them are the same as Brushkiller 875.

Edit: Came across another list. It's probably the same, but I'll post it in case there are any differences.

Most stuff is a hour. I know gramoxone and roundup are less than that from first hand experience not sure what there label says. But 6 hours is a long time.
