Trichoderma is a genus of fungi that is present in all soils, where they are the most prevalent culturable fungi. Many species in the genus can be characterised as opportunistic avirulent plant symbionts. Several strains of Trichoderma have been developed as biocontrol agents against the fungal disease of plants. The various mechanisms include antibiosis, parasitism inducing host-plant resistance and competition. Most biocontrol agents are from the species. T.harzianum, T. varied and T. hamatum. The biocontrol agent generally grows in its natural habitat on the root surface and so affects root disease in particular but can also be effective against the foliar disease.
