OJITO-RAMOS, Katia; CUPULL SANTANA, René  and  PORTAL, Orelvis. Effects on the soil microbiota of Citrus spp. extracts with antifungal activity. Ctro. Agr. [online]. 2020, vol.47, n.4, pp. 12-16.  Epub Oct 01, 2020. ISSN 0253-5785.

The soil microbiota plays an important role in agricultural ecosystems, so it is essential to protect it. To safely apply fungicides of natural origin such as hydroalcoholic extracts of Citrus spp., that present antifungal activity against tomato phytopathogenic fungi, it is necessary to determine the effect of these on the soil microorganisms. The extracts were obtained by ultrasound extraction and the microbiological analysis of the substrate under study was carried out after their application. Bacteria, total fungi, actinomycetes, azotobacter and cellulolytic fungi were evaluated. The extracts did not show any negative effects on the soil microbiota, so they could be used in the agroecological control of tomato diseases.

Keywords : microbiological analysis; agroecological control; tomato.
