If the plant has aerial tubers which will drop and germinate if the plant is disturbed too much, and the stem is too small to be frilled with a chisel, but can be scraped without cutting through, scrape along the stem of the plant for approximately 15 cm to expose vascular tissue and then apply chemical within less than 30 seconds after the beginning of the scrape.
Once chemical is applied, do not take any further action or disturb the plan until it is completely dead. Any plant material that may have seed or could resprout should be removed and disposed of responsibly. Ensure any material left does not increase the local fire hazard.
