Glyphosate Watering Can

Hi all,

Brief question - I bought a new, red watering can to use at the allotment, to distribute Glyphosate (please don't judge - I have a horsetail epidemic and it was an absolute last resort!)

My question is, being rather short of a watering can up there, can I use the weedkiller one for normal watering? Only I understand that Glyphosate does not linger in soil and is deactivated within a very short space of time. Could residue linger in the can once mixed with water?

Cheers

We have a back pack sprayer specifically for when spraying with it. We too use it, have too, I'm not prepared to spend time weeding all what can be done with the spray. If you rinsed your can out well enough I can't see it would be a problem, or just go buy another can and keep the red one for noxious stuff :D

The standard advice is no, you can't. But I suspect that's just the manufacturer avoiding potential lawsuits. If the watering can is plastic, then it's very unlikely that any trace of glyphosate will remain after you've thoroughly rinsed it out. The big problem is that glyphosate takes so long to have any effect, so you won't know for a couple of weeks and possibly longer.

I'd say rinse well and then use the can for watering. On the other hand, don't sue me if I'm wrong.

I am fighting horsetail by painting glyphosphate with a brush rather than spraying. I also use 1 pint plastic milk containers with a hole in the lid to thread bindweed though. This works pretty well but I do have quite a few dotted around the garden.
Has anyone seen the plot, I seem to have lost mine?
