It may be an eradicant, applied to a plant, plant part, or the environment as a curative treatment to destroy fungi established within a given area or plant; or preferably it may be a protectant, applied to protect a plant or plant part from infection by killing, or inhibiting the development of, fungal spores of mycelium that may arrive at the infection court. A bactericide is a toxicant or poison for bacteria. Among the more recent bactericides are antibiotics, products of other living organisms. They also have value against certain fungi. There are also a few virocides, which are toxic or poisonous to viruses.
