Abstract

Brazil is the third largest agricultural exporter in the world, but the diseases and pests that attack different crops represent a great challenge to production expansion. According to FAO, the relative consumption of pesticides in the country was 4.31 kg of pesticides per hectare cultivated in 2016. In view of the high consumption of pesticides that do not always control pests and diseases, in addition to causing environmental and health damage human, the pesticide industry is looking for biological agents that can be an alternative method to control these pests and diseases, which when not controlled can cause losses of up to 80% in production. Symbiotic bacteria of entomopathogenic nematodes (Xenorhabdus and Photorhabdus), actinomycetes and bacteria of the genus Bacillus are characterized by the production of antimicrobial compounds and insecticides that can serve as a potential source of new biological pest and disease controllers in plants. This project aims to evaluate bacteria symbionts of entomopathogenic nematodes, actinomycetes and Bacillus obtained from extreme environments for their potential to inhibit the growth of phytopathogenic fungi and bacteria, and cause mortality of mites, insects and phytoparasitic nematodes. The most efficient bacterial compounds on microorganisms will be identified by liquid chromatography coupled with mass spectrometry. With the results obtained, we hope that there will be the development of products for use as biological defensives. (AU)
