Advances in biocontrol of Botrytis cinerea by Trichoderma spp.

Abstract:

Biological control of plant diseases is an effective way to reduce chemical pesticides and environmental pollution. Trichoderma spp. are important biocontrol fungi that play a key role in controlling plant disease. Some studies indicate that Trichoderma are widely used to Botrytis cinerea control. At present, screening, application and biocontrol mechanism of Trichoderma against B. cinerea are widely studied. Interaction between Trichoderma and B. cinerea can activate multiple antagonistic mechanisms of Trichoderma. One of the biocontrol mechanism of Trichoderma is direct mechanism, including the hyperparasitism, antibiotic and competition. The other, indirect mechanism, is the induced system resistance of plant by Trichoderma. We reviewed the mechanism of Trichoderma against B. cinerea including the interaction model, signal transduction pathway and the induce defense response of plants, for an efficiency application of Trichoderma as biocontrol agents.
