The stem injection of hollow cane non-native plants is recognised as the most successful and ecologically sound herbicide application method. Stem injection is controlled and specific to the target species, so the treatment can be completed in all weather conditions and near water with the relevant applicator licences.

How does it work?

A small, measured dose of herbicide is injected into each cane of the Japanese Knotweed infestation. This allows the herbicide to translocate throughout the roots and rhizome of the plant. When used on healthy, vibrant plants, one correctly applied treatment is sufficient to eradicate the infestation.

In the years since Stem Injection Systems (SIS) first launched its system, stem injection has become the most reliable, fit for purpose system for contractors and ground maintenance teams on more and more tender specifications.

Stem injection of herbicide continues to establish itself as one of the most popular and effective methods of treating non-native, invasive plants, despite a backdrop of continued uncertainty over the future use of glyphosate. Stem injection has continued to enhance its reputation as a most viable treatment method.

Tool Use and Care

  • The optimum time for injecting canes is June through first frost. Canes may split if injected prior to June.
  • For use in the UK, follow the Government and herbicide manufacturers requirements.

  • Inject canes that are three quarters of an inch or larger between 1st and 2nd node above root crown.
  • After using the JK Injection Tool, fill the cup with water and squirt until empty. Rinse and soak cap with water to clean out check valve. Failure to clean the 3 check valves used in the JK Injection Tool will prevent the tool from functioning and is not covered under the warranty.
  • When the JK Injection took is not in use, store the needle in the ml measuring tube to prevent physical injury.

Quality product you
Model: 18 SqFt(1.7 SqM), Model: 18 SqFt(1.7 SqM)
Summary: Great quality product, priced right. Cuts and installs easy-follow the instructions people!! PRO TIP-you don’t need to cover every square inch. OVERKILL!! Think about it-when a bell rings you could put your fingers on the edge and silence it right? Same rules apply here. A strip or square will isolate the vibration and notice when placed correctly— knock on the surface and see what vibrates or what part makes the loudest drowning and that’s a good clue of where you should put a piece of this…unless you’re trying to use it for temperature insulation no need to go ape on it. If you look at the bottom of a stainless steel sink, it’s got a stripe or a small sticker of insulation that keeps it from rattling. You can do that here. What’s important to note is the instruction specifically say use a roller to roll the ribs out until it’s smooth that way you’ve got maximum adhesion. I see a lot of pictures and videos from people that finished their install and didn’t follow this simple instruction. It makes sure that it’s stuck down before you put all your paneling and carpet back in and it’s a small step with a cheap wooden roller it’s easy. I’ll say the installation with this product is a breeze. You can use sharp scissors or a blade. It does get gummy after a while, and you may need to clean off your blade or your scissors, but it cuts very well and the ribs make it easy to size in space the thickness is fantastic and the backing paper comes off quite easily. I’ve done lots of installations with Graphics emblems you name it and this product is very easy to use and represents good value.

Good stuff !
Model: 36 SqFt(3.4 SqM), Model: 36 SqFt(3.4 SqM)
This is an excellent product. Easily moldable, cuttable with good scissors or razor knife, very sticky, works great. This pack was enough to do all 4 doors on a crew max truck, and I went wild on the fronts. I used 9 peices on each rear door which was just enough, and the rest on the fronts. I doubled up layers and even used some on the back of the door panels. If you follow the instructions and dont go wild you might even have extra left over. It works just like you would imagine. Without doing the entire cab there will still be road noise but this helped noise, better audio, no buzzing door panels, terrific improvement. It is kind of heavy, so extra weight is added to truck, but that really isnt a bad thing. It is noticable but in a good way. Get it. Use it.

Great product - Add foam product for complete solution
Model: 36 SqFt(3.4 SqM)
Used in two cars with speaker upgrades. Easy to install but get the roller for assured adhesion.removes "tinnyness" from large metal resonators. Use with foam absorptive material for a complete system.
