Herbicide Injector Units and Needles

[Sympatricko 0]

I am currently looking at different herbicide injector devices to best treat Japanese Knotweed. Does anyone have any recommendations for a supplier and what types of needles to buy? Any information would be greatly appreciated.

I am in the same process and would love to hear some feedback on this. I planned to get a few extra needles, but there are a few types and was curious on the best ones to get/most useful ones.

A few years ago NWMISN shopped around for herbicide injectors, particularly for Japanese Knotweed. The best price we found was actually a model from the UK:

It cost ~$100 USD. They are well built and come with a variety of needle types and spare parts. No issues to report thus far so it may be an option to explore. Hope that helps!
