The objective of this study was to evaluate the effects of exposure of the nematode Heterorhabditis amazonensis MC01 to soil fertilizers containing different active ingredient, verifying their influence in the viability, infectivity and nematode production in Tenebrio molitor L. larvae. Nine products were tested, including fertilizers and soil conditioners, using the adapted IOBC/WPRS protocol. The infective juveniles were exposed to the highest concentration recommended by the manufacturer of each product for a period of 48 h. After this period, the viability, infectivity and production were evaluated and the values of mortality, infectivity reduction, production reduction and insecticide effect were obtained in order to classify the products according to IOBC criteria. In this way, the nematode H. amazonensis MC01 was compatible with most of the products under the tested conditions, so could be present in the soil at the same time. However, the product Nutriterge® Formula 3 was considered slightly harmful and Nem out® considered harmful. However, further field tests should be performed with these products to prove the deleterious effect on the nematode tested.Nematoides entomopatogênicos são inimigos naturais de insetos-praga presentes no solo; no entanto, o uso de insumos agrícolas pode afetar a ação desses organismos. O objetivo deste estudo foi avaliar os efeitos da exposição de Heterorhabditis amazonensis MC01 com fertilizantes de solo contendo diferentes ingredientes ativos, a fim de verificar a influência na viabilidade, infectividade e produção do nematoide em larvas de Tenebrio molitor L. Foram testados nove produtos, incluindo fertilizantes e condicionadores de solo, utilizando o protocolo adaptado da IOBC/WPRS. Os juvenis infectantes foram expostos à maior concentração recomendada de cada produto por período de 48h. Após, esse período os valores de viabilidade, infectividade, redução da produção e efeito inseticida foram obtidos e os produtos foram classificados de acordo com os critérios da IOBC. Dessa forma, o nematoide H. amazonensis MC01 foi compatível com a maioria dos produtos nas condições testadas, podendo estar presente no solo ao mesmo tempo. No entanto, o produto Nutriterge® Fórmula 3 foi considerado ligeiramente prejudicial e Nem out® foi considerado prejudicial. Outros testes de campo devem ser realizados com esses produtos para comprovar o efeito deletério sobre o nematoide testado.engUniversidade Federal de Minas GeraisUFMGBrasilICA - INSTITUTO DE CIÊNCIAS AGRÁRIASBioscience JournalAgricultura orgânicaNematóides entomopatogênicosAdubos e fertilizantesbiological controlHeterorhabditidaeorganic agricultureplant extractCompatibility of Heterorhabditis amazonensis MC01 (Nematoda: rhabditida) with fertilizers and soil conditionersCompatibilidade de Heterorhabditis amazonensis MC01 (Nematoda: Rhabditida) com fertilizantes e condicionadores de soloinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articlehttps://seer.ufu.br/index.php/biosciencejournal/article/view/44258Vanessa AndalóFernando da Silva RochaLucas Silva de Fariainfo:eu-repo/semantics/openAccessreponame:Repositório Institucional da UFMGinstname:Universidade Federal de Minas Gerais (UFMG)instacron:UFMGLICENSELicense.txtLicense.txttext/plain; charset=utf-82042https://repositorio.ufmg.br/bitstream/1843/49161/1/License.txtfa505098d172de0bc8864fc1287ffe22MD51ORIGINALCompatibility of Heterorhabditis amazonensis MC01 (Nematoda rhabditida) with fertilizers and soil conditioners.pdfCompatibility of Heterorhabditis amazonensis MC01 (Nematoda rhabditida) with fertilizers and soil conditioners.pdfapplication/pdf533090https://repositorio.ufmg.br/bitstream/1843/49161/2/Compatibility%20of%20Heterorhabditis%20amazonensis%20MC01%20%28Nematoda%20rhabditida%29%20with%20fertilizers%20and%20soil%20conditioners.pdfc65bf793fbd1de58cd0ff472860156f4MD521843/491612023-01-26 10:11:14.951oai:repositorio.ufmg.br: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Repositório InstitucionalPUBhttps://repositorio.ufmg.br/oaiopendoar:2023-01-26T13:11:14Repositório Institucional da UFMG - Universidade Federal de Minas Gerais (UFMG)false
