Has anyone used Resolva weedkiller? What do you think of it?

People use it on our site. It's a glyphosate based systemic herbicide so it acts through the leaves down to the rest of the plant. This stuff actually makes the plant wilt quickly so you can see a quick result. It's quite expensive but you can get special offers.
Personally I just buy generic glyphosate and use it in a watering can or sprayer (that I don't use for anything else!) I find that my battle with bindweed needs some heavier weapons on my side.
As with all garden chemicals, read the label and wear gloves.

I found the measuring cap very confusing.  But once I applied it at the correct dilution rate  it was very effective.

I have a spray bottle and find it kills things deader than a doornail, just as it says.
