Biofungicdes are live organism formulations that are used to limit the activities of fungus and bacteria that cause plant disease. Bio fungicides are based on studies of natural processes in which helpful microorganisms, usually extracted from soil, prevent plant diseases from reproducing. Biocontrol microorganisms are active in the environment and are free-living fungus, bacteria, or actinomycetes.
Biofungicides control other microorganisms in the four following ways:
▶ Through direct competition, biofungicides grow a defensive barrier around the root system, or rhizosphere, thereby shielding the roots from harmful attacking fungi.
▶ Biofungicides also produce a chemical similar to an antibiotic, which is toxic to the invading pathogen. This process is called antibiosis.
▶ Additionally, biofungicides attack and feed on the harmful pathogen. The biofungicide has to be in the rhizosphere either before or at the same time as the pathogen. Predation by the biofungicide will not affect the harmful pathogen if introduces after it has infected the roots.
▶ Lastly, introducing a biofungicide kickstarts the plant’s own immune defense mechanisms, enabling it to successfully fight off the invading harmful pathogen.
Abstract. Fungal and viral infections are difficult to treat, since fungal infections commonly rebound after suppression by the antifungal agent and current antiviral drugs are only virustatic, allowing the virus to reassert its pathogenicity if not eliminated by the host defenses.
