What is stem injection?

Stem injection is a process by which herbicide is injected directly into a plants hollow cane. This unique method is particularly effective with the invasive plant species know as Japanese knotweed. By injecting herbicide into the plants crown, as apposed to an external application you increase the transfer of herbicide throughout the plant systems roots. Not only is stem injection more effective then other forms of herbicide but since the application is done within a plants crows as applied to being applied via a spray it poses less of a threat to the surrounding vegetation.
