Biopesticides and Biofertilizers Based on Fungal Secondary Metabolites

摘要

Hundreds of secondary metabolites produced by beneficial fungi have been isolated and characterized, mainly from biocontrol strains of the genus Trichoderma. The production of these natural compounds is strain dependent and varies on: i) the compound considered; ii) the species and the strain; iii) the presence of other microbes; iv) the balance between elicited biosynthesis and biotransformation rate; v) the growth conditions. In some cases, the biocontrol agent is able to modulate the production of toxic secondary metabolites according to the presence or the absence of the target pathogen [1].
