Abstract


Biological control is considered a natural tool and an ecological alternative to overcome the problems caused by chemical methods for the protection of plants. From the fungi with potential of antagonism, the genus Trichoderma is one of the most researched and studied. This fungus is a microorganism naturally found in soil, which presents an important ecological function, and participates of several processes in this mean. The objective of the work is to develop a discussion about aspects of the biological control, specially in relation to effects of the fungus Trichoderma spp. in the biocontrol of pathogens of agricultural crops. With the discussions along the texts, it is considered that the biological control is a system which is being target of frequent and continuous investigation being an important tool for the control of several problems of phytossanity which occur in agriculture. Among the agents which are noteworthy in the investigations is the fungus Trichoderma spp., in which it was verified action as biocontrol agent and in some cases as growth promoter.
