The Green Shoots® Stem Injector Kit is for injecting weed killer or other chemicals into plants. It is especially useful for invasive knotweed.
For woody or tough stems a drill should be used. For green, hollow stems, a sharp needle can be used (SOLD SEPARATELY - See links below).
The advantages of injection are:
- Highly effective
- Precise
- Less weather dependent (It can be used when rain is forecast.)
OUR KIT CONTAINS:
- The injector with:
- Contoured, full hand-grip reduces fatigue
- Adjustment mechanism for precise dosing from 0 to 6 milliliters
- Two 12-gauge blunt tip stainless steel needles (NOTE: you must use a drill with these (sold separately)).
- Wrench for tightening needles on injector
- Three empty injector reservoir bottles with caps: 12 oz. (355 ml)
- White paint marker for making highly visible marks on treated stems
SHARP NEEDLES AND DRILLS (click on links below):
Use the sharp needle for green stems. For tough, woody stems, use one of the drill options:
2.) Hand-Twist Drill with Carbide Tip: (Click Here)
3.) Knotweed Drill Bit for Use With Electric Drill: (Click Here)

The injector works well with no leaking of the herbicide and ease of application, however when injecting multiple targets plants there is a suction vacuum that builds up because there is no one way pressure release valve which would be impossible to make in a 12oz bottle. Just have to unscrew the bottle, let it equalize and reinstall when the bottle starts to collapse. Good for my intended purposes.
Kealii,
Thanks for this comment. Sorry for the late response. This problem can be fixed easily. Here's a 1 minute YouTube video explaining how to remedy the problem. https://youtu.be/i1xISdNs8SA
I ordered the injector kit from Green Shoots after several years of trying various herbicides and cutting strategies to eradicate Knotweed with little success. The kit arrived within days, the package instructions made it very easy to set up and use. The Green Shoots website discusses the best time to use the injector in the rather short period between the end of flowering and first frost, along with how and where to inject stalks is best so the herbicide gets to the rhizomes and root base that can be 10’ deep as the Knotweed draws nutrients back into the roots for next season growth.
It took about a week following injection and foliage spraying before the leaves started turning yellow, indicating the herbicide was functioning. I reapplied foliage spray about 2-weeks after the initial treatment and reached some large stalks that missed injection the first . That also took about a week for visible results. Once winter is done I will remove the dead stalks from each of the stands and follow the Green Shoot instructions for early season treatment, followed by late season injections.
This can be a multi-year process to fully eradicate Knotweed, likely followed by close inspection for a while after that to be sure none of the plant survives. Patience being the ultimate tool in this process. Injection appears to be the best delivery method to a plant and it’s root system that resists most any other technique. However, initial results are welcome to see and every indication is full eradication over the next year or so with the use of the Green Shoots injection system.
Nothing else needs to be said. I would highly recommend purchasing from Green Shoots.
The injector was easy to put together and easy to use. I was a little worried that injecting would be a huge hassle but it really wasn’t. Took me about 2 hours to do a stand about 20’ wide and 60’ long. Three bottles of glyphosate at a 2ml dose.
