Just Knotweeds – 1000 injections per day.
The JK1000. Made in Tacoma, WA USA.
The JK1000 was made for knotweeds. It’s been killing them for over 30 years. Mostly used by the government this tool can now be purchased online. This tool is used when spraying is not an option or the location to be treated is in a sensitive habitat. It is almost completely effective on the first treatment as the herbicide is delivered to the roots far more efficiently than via the leaves. You do not have to hit every cane in the knotweed clump, just 2/3 of them.
Customers use their liquid herbicide (Glyphosate is still #1 recommended and #2 is Imazapyre) and inject it (using a specially designed needle) into the stem of the knotweed plant. The hollow cane will hold the herbicide inside the plant. Injecting 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 after 72hrs of treatment and not worry about regrowth.
This tough lightweight tool is designed to work in the weeds. 16oz capacity with an adjustable delivery for concentrated herbicides. A good feeling grip with an easy to tighten lid. No cords or tubes to get in your way. All stainless steel and brass components to prevent corrosion.
