Aim: The purpose of the paper is to revise the multiple methods of biological control of Trichoderma spp. The need to reduce the use of fungicides in phytosanitary control and makes it necessary to develop technologies that allow easy, economical and effective ways to obtain products from endogenous microorganisms with sufficient quality and quantity to their application in the crops areas. In addition to the industrial importance of the genus, certain Trichoderma species have the ability to antagonise plant pathogens. Trichoderma interacts with other microorganisms, but mainly with pathogenic fungi. These interactions include hyperparasitism, competition, and antibiosis. Hyperparasitism is connected with the direct contact of an antagonist with a pathogen and is composed of such stages as: pathogen recognition, attack, gradual penetration of the pathogen cells and death. Contamination of crops with phytopathogenic genera such as Fusarium, Aspergillus, Alternaria, and Penicillium usually results in mycotoxins in the stored crops and are designated as the most devastating species for small grain cereals.
