Notes: A reward from Dungeoneering. Can be bought with 34,000 Dungeoneering tokens and requires level 21 Herblore and 21 Dungeoneering to use.

When used, Herbicide will destroy any herbs that monsters drop, giving you twice the amount of Herblore experience should you have cleaned it. To select which herbs you would like eroded, right-click and select 'Inspect' on the Herbicide. Once an interface appears, select your choices.
