We surveyed the capability of producing pesticide compounds from a cultivable fungal community isolated from oligotrophic soil of continental Antarctica. A total of 115 fungal isolates were obtained and cultivated to obtain their crude extracts, which were screened to detect antifungal, insecticidal and herbicidal activities. The extracts of Aspergillus sydowii, Penicillium allii-sativi, Penicillium brevicompactum, Penicillium chrysogenum and Penicillium rubens displayed antifungal and herbicidal. Bioactive extracts were examined using 1H NMR detected the presence of secondary metabolites with chemical shifts. Our results show that the fungi present in cold-oligotrophic soil from Antarctica included dominant species, which may represent a unique and interesting source to discover prototype molecules with biopesticide activities.
