Considerations for Herbicidal Spraying

• Proximity of knotweed to watercourses
• Sensitivity of other species near by
• Size and density of the infestation
• effect of residual herbicides on tree roots
• Potential harm to protected wildlife

Herbicidal applications on done by spraying, leaf wipe or stem injection. The precise method depends on the situation and location of the infestation. Combined methods will often be used.This will ensure that the correct herbicide is chosen for the job, at the right strength, applied correctly and at the most effective time of year.
