The InjectorDos Pro is a precision-engineered stem injection tool designed for the direct application of systemic herbicides into the stems of invasive plants such as Japanese Knotweed, Hogweed, and Himalayan Balsam. This method ensures minimal environmental contamination and maximum herbicide uptake by targeting the plant's internal structure, delivering results with significantly reduced chemical use.
Perfect for use on sensitive sites near watercourses, public spaces, or environmentally sensitive habitats, the InjectorDos Pro supports compliance with UK best practice guidance on non-chemical and precision-based weed control.
