RESUMO:

The increase in costs of chemical control for pests and pathogens, the loss of efficiency of some of these products over time and the environmental problems resulting from these practices indicate the need to search for alternatives for the control of phytopathogens. Some groups of organisms have been known to inhibit the development of microorganisms potentially pathogenic to agricultural crops. The selection of antagonistic microorganisms as well as the knowledge of their mechanisms of action constitutes the fundamental basis of any biological control program of plant diseases and is essential in the development of rational models for the introduction of biocontroladores in agroecosystems. For most isolates described in the recent literature, it is known that the antagonistic effect can be explained based on the intense production of specific cellular secondary metabolites. The success of commercial production is based on the knowledge of the viability of these products according to their metabolism. In view of the above, this work aims to present and discuss the metabolic and genetics of microorganisms potentially antagonistic to pests and parasites that attack agricultural crops, and from the description of these mechanisms identify molecules derived from bacterial metabolism for commercial formulations for biological control.
