The aim of this study was identifying the root rot causal agents in cassava, cv Rosinha, in Alagoas state, Brazil. Pathogen species were studied, which are responsible for root rot in cassava, through isolation, morphological characterization and pathogenicity confirmation. Fusarium sp was emphasized among other isolated genera, which is pathogenic to cassava roots and plants. The phylogenetic study was based on the ITS region of the constructed DNA, using the ‘‘maximum Likelihood Tree’’ method, with a base of 1000 “bootstrap” replicas, what showed 100% of genetic similarity to Fusarium falciforme.

Several are phytopathogens that limit the production of cassava (Manihot esculata Crants) being rot of the roots to which they marry the greatest loss in the crop reaching 70%. This culture is of high interest to the Northeast region of Brazil, providing great losses. The difficulties in management have directed the search for alternatives, among which, biocontrollers have shown significant results. This literature review aimed to gather information related to the rot of cassava root cv Rosinha, the main phytopathogens and antagonistic activities of Trichoderma in the control of diseases in the state of Alagoas. A bibliographic survey was carried out in the databases Scielo, Google Acadêmico, Capes portal (theses and dissertations), journals and books. To obtain information on: root rot of table cassava, Trichoderma spp., as a biocontrol agent of phytopathogens.

Vários são fitopatógenos que limitam a produção de mandioca (Manihot esculata Crants) sendo podridão das raízes a que casam a maior perda na cultura chegando a 70%. Esta cultura é de elevado interesse para a região Nordeste do Brasil, proporcionando grandes prejuízos. As dificuldades no manejo tem direcionado a busca por alternativas, entre as quais, o biocontroladores vem apresentando resultados significativos. Esta revisão bibliográfica teve como objetivo reunir informações relativas à podridão da raiz da mandioca cv Rosinha, os principais fitopatógenos e as atividades antagônicas de Trichoderma no controle das doenças no estado de Alagoas. Foi realizado um levantamento bibliográfico nas bases de dados Scielo, Google Acadêmico, portal da Capes (teses e dissertações), periódicos e livros. Para obtenção de informações sobre: podridão radicular da mandioca de mesa, Trichoderma spp., como agente de biocontrole de fitopatógenos.

Einige sind Phytopathogene, die die Produktion von Maniava (Manihot esculata Crants) begrenzen, die Fäulnis der Wurzeln sind, mit denen sie den größten Verlust in der Ernte heiraten und 70% erreichen. Diese Kultur ist für die Region Nordostbrasilien von großem Interesse und verursacht große Verluste. Die Schwierigkeiten im Management haben die Suche nach Alternativen geleitet, unter denen Biocontroller signifikante Ergebnisse gezeigt haben. Diese Literaturrezension zielte darauf ab, Informationen über die Fäulnis der Maniokwurzel cv Rosinha, die wichtigsten Phytopathogene und antagonistische Aktivitäten der Trichodermie bei der Bekämpfung von Krankheiten im Bundesstaat Alagoas zu sammeln. Eine bibliographische Umfrage wurde in den Datenbanken Scielo, Google Acad’mico, Capes Portal (Thesen und Dissertationen), Zeitschriften und Büchern durchgeführt. Um Informationen über: Wurzelfäule von Tischmaniok, Trichoderma spp., als Biokontrollmittel von Phytopathogenen zu erhalten.
