I've got a lot of area on our property that's near water. There's a >hundred yard creek that crosses from the back fence to the road out front (then continues on under the road and onto the neighbors property), a large area (~50yd x 20yd) that's flooded (because of the neighbors dam - long story), a mid-sized pond (~75yd x 15yd) and a berm that parallels the roadside drainage ditch.
The vegetation in those areas grows - fast. Faster than I can cut with a string trimmer. Not to mention that a) it takes multiple days to cut those areas & I've got other things to do & b) I've killed 3 trimmers over the last few years trying to keep it all cut down.
From what I've read, one shouldn't use glyphosate near water. I can't find a reason why not, except for one paper that seemed to be biased against the use of glyphosate in any location.
There was something that had me go WTF does that mean???
FISH TOXICITY
96 hour LC50, Rainbow trout – 8.2 μg/L (technical)
96 hour LC50, Bluegill – 5.8 μg/L (technical)
So, in plain English, why should I not use it near water?
