The Stem Injector Kit consists of a handheld compression sprayer (7.6L or 4.7L), the Dosimeter and the Stem Injector needle. The image shows the kit with the 7.6L Compression Sprayer. To see the 4.7L click here.

The kit enables targeted and precise doses of herbicides such as glyphosate and pesticides to be directly injected into the stems of plants such as Japanese knotweed, Himalayan balsam and giant hogweed.

!!! Use NOW with Round-up Pro Vantage 480 to combat Japanese knotweed at a rate of 2ml per stem. Buy Round-up Pro Vantage here !!

The Dosimeter and Stem Injector Needle can also be purchased below for use with any of our other Guarany backpack sprayers.

The Dosimeter allows for highly accurate and consistent volumes of fluid to be delivered with each squeeze of the trigger. Benefits of the Dosimeter include:

  • Can be calibrated to deliver between 2ml and 25 ml of fluid per stroke
  • The same fluid is delivered regardless of backpack pressure
  • Improved safety for the operator as the spray is directly only at the plant
  • Gives completely consistent dosing
  • Reduced chemical waste
