Bioherbicide

A bioherbicide (or biopesticide) is a herbicide that is based on a living organism, such as fungi, bacteria or protozoa, which eats or renders vulnerable the pests that the user wishes to eradicate. A bioherbicide based on a fungus is called a mycoherbicide.

Their most important advantage, is that you can choose an organism that doesn't threaten other organisms besides the chosen pest, and the controls needed to enable consumption are practically non-existent or easier to apply.

Among their disadvantages though, are that the chosen organism may have harmful results on other beings besides the controlled pest.
