Stem scrape


                      

Stem scraping is used for plants and vines with aerial tubers. A sharp knife is used to scrape a very thin layer of bark from a 10 cm section of stem. Herbicide is then immediately applied to the exposed soft underlying green tissue.
This method is also called bark stripping or stem painting. Some woody weeds can have their bark surface peeled away and the exposed wood painted or sprayed with herbicide.
