Frequently Asked Questions

Why use stem injection instead of traditional spraying?

Stem injectors deliver herbicide directly into the plant’s vascular system, minimizing drift, protecting sensitive areas, reducing waste, and often moving more effectively through roots and rhizomes than spraying.

Do I need training to use stem injection equipment?

In the UK, competence in stem injection application is required under the PA6INJ handheld injection equipment qualification if you are applying pesticide professionally. This includes training on calibration, risk assessment, and safe use of the applicators

Are stem injectors easy to use?

Yes, they are generally hand‑operated and lightweight, though proper use requires careful handling of needles and herbicide. Most are designed for field use and are easy to clean and maintain after use.
