How much and what type of herbicide do you recommend for knotweed?
5mls per cane of Glyphosate or Imazapyr is what we recommend. These active ingredients come in a variety of herbicides. Imazapyr is practically non-toxic (the EPA’s lowest toxicity category) to fish, invertebrates, birds and mammals. The preponderance of evidence confirms that glyphosate does not harm plants by interfering with mineral nutrition and that it has no agriculturally significant effects on soil microbiota. Glyphosate has a lower environmental impact quotient than most synthetic herbicide alternatives. When injected these herbicides kill the plants they are intended to kill with the lowest risk to the surrounding environment.

How does Glyphosate work?
Glyphosate works by halting a specific enzyme pathway that only exists in plants and some microorganisms. This in turn prevents plants from producing certain proteins that are needed for growth. Glyphosate is absorbed through foliage and then moves to growing points within the plant. Glyphosate is only active on growing plants and is not effective as a pre-emergence herbicide.
How does Imazapyr work?
Imazapyr belongs to the imidazolinone family of herbicides that act by inhibiting acetolactate synthase (ALS) (Herbicide Group B), the first enzyme in the catalysis of the branch-chain amino acids valine, leucine and isoleucine necessary for protein production and cell growth.
How safe is Glyphosate?
Glyphosate was registered by the EPA in 1974. It has been classified by the organization as toxicity class III on a scale of I-IV, with IV being the least dangerous. Also, it has not been found to be a carcinogen. Glyphosate has low toxicity for fish and other wildlife and biodegrades in soil with a low likelihood of reaching groundwater.
How do I calibrate the JK1000?
- Using the provided allen wrench you will find an adjustment screw behind the trigger. You can access the screw and turn it RIGHT to increase the delivery amount and LEFT to decrease the delivery amount.
- 1 TURN = 1ml
- Use the provided vial that the needle comes in to measure delivery.
- Each marking line is 1ml on the needle vials.
