Other microbial formulations include Fungi in the genus Trichoderma that have been known since at least the 1920s for their ability to act as biocontrol agents (a term coined for beneficial organisms with ability to suppress pathogens) with successful results in maize (Harman 2006). Trichoderma species grow naturally around the plant roots and feed or parasitize on pathogenic fungi. However, if pathogenic fungi are not present in the soil, addition of Trichoderma can have little or no benefits as they will die‐off without feeding on pathogens (Ingham 2005, Sullivan 2004).
