Just Knotweeds – 1000 injections per day.
The JK1000. Made in Tacoma, WA USA.
The JK1000 can be used on tough Bamboo and other woody species, even trees. It was made for knotweeds though and it’s been killing them for over 30 years. Mostly used by the government and larger aquatic care groups this tool can now be purchased online.
This tough but lightweight tool is designed to work in the weeds. 16oz precise delivery of liquid pesticides or herbicides and a good feeling grip with an easy to tighten lid and 1-8mls per shot adjustability. No cords or tubes to get in your way. All stainless steel and brass components. Custom durable needles that inject out of the base not the tips to load canes. Rinse it out well and it’ll last you a lifetime and definitely take care of your knotweed problem. Good hunting out there and get the right tool for the job.

ATTENTION for 2026 WE ARE SOLD OUT!!!
WE WILL HAVE NEW TOOLS IN JAN OF 2027. NEEDLES STILL AVAILABLE.
Injecting above the root crown into the hollow cane (between nodes) delivers a dose of herbicide directly into the knotweed plants vascular system. This will kill the plant. You will see it turn brown in about 2-3 weeks. You can cut and transport the canes and leaves within 72hrs of treatment and not worry about regrowth.
We have spray tips converting the JK1000 into a handheld sprayer.
MADE IN THE USA.
