Resumo: This study aimed to evaluate the effectiveness of different dosages of a product based on seaweed extract from Ascophyllum nodosum in the management of green mold in citrus postharvest. Dosages of 0; 25; 50; 75 and 100 mL L-1 were used of the commercial product based on seaweed extract and, as a comparison, a systemic fungicide from the benzimidazole group was used. In vitro experiments were carried out to check the effect of the product and its possible mechanisms of action, the following parameters being evaluated: mycelial growth, sporulation, electrolytes leakage and fungicidal and/or fungistatic activity. Then, an in vivo experiment was carried out in order to assess the incidence and severity of green mold in 'Valencia' orange fruits. It was observed that the dosages of 75 and 100 mL L-1 were the most effective in reducing mycelial growth and the production of conidia of the pathogen, with a fungistatic effect of the product based on the seaweed extract. It was found that the product modify the plasma membrane permeability of the fungus at the dosage of 100 mL L-1, which may be a possible mechanism of action on the pathogen. In addition to being able to reduce the incidence and severity of green mold in postharvest on orange fruits at dosage of 75 mL L-1. Thus, it is concluded that the product based on the A. nodosum seaweed extract can be included in the integrated management of diseases in postharvest of citrus.

Dosis de 0; 25; 50; 75 y 100 mL L-1 del producto comercial a base de extracto de algas y, a modo de comparación, un fungicida sistémico del grupo de los benzimidazoles. Se realizaron experimentos in vitro para verificar elefecto del producto y sus posibles mecanismos de acción, evaluando los siguientes parámetros: crecimiento del micelio, esporulación, pérdida de electrolitos y actividad fungicida y/o fungistática. Luego, se realizóun experimento in vivo para evaluar la incidencia y severidade del moho verde en frutos de naranja 'Valência' tratados com el producto. Se observó que las dosis de 75 y 100 mL L-1 fueron las más efectivas em la reducción del crecimiento del micelio y la producción de conídios del patógeno, com efecto fungistático del producto a base del extracto del alga A. nodosum. Se encontró que el producto aumenta la permeabilidad de la membrana plasmática del hongo a dosis de 100 mL L-1, lo que puede ser un posible mecanismo de acción sobre el patógeno, además de poder reducir la incidencia y severidade del moho verde poscosecha en frutos de naranja a una dosis de 75 mL L-1. Por tanto, se concluye que el producto a base del extracto del alga A. nodosum puede incluirse en el manejo integrado de las enfermidades poscosecha de los cítricos.Objetivou-se com o presente trabalho avaliar a eficácia de diferentes dosagens de um produto à base de extrato da alga Ascophyllum nodosum no manejo do bolor verde em pós-colheita de citros. Utilizou-se as dosagens de 0; 25; 50; 75 e 100 mL L-1 do produto comercial à base do extrato da alga, como comparativo, um fungicida sistêmico do grupo dos benzimidazóis. Foram realizados experimentos in vitro para verificar o efeito do produto à base do extrato da alga e seus possíveis mecanismos de ação, por meio das seguintes análises: crescimento micelial, esporulação, perda de eletrólitos e atividade fungicida e/ou fungistática. Em seguida, realizou-se experimento in vivo a fim de se avaliar a incidência e severidade do bolor verde nos frutos de laranjeira ‘Valencia’ tratados com o produto. Foi observado que as dosagens de 75 e 100 mL L-1 foram as mais eficazes na redução do crescimento micelial e da produção de conídios do patógeno, sendo constatado um efeito fungistático do produto. Verificou-se que o produto altera a permeabilidade da membrana plasmática do fungo na dosagem de 100 mL L-1, podendo ser um possível mecanismo de ação sobre o patógeno, além de ser capaz de reduzir a incidência e a severidade do bolor verde em pós-colheita nos frutos de laranjeira na dosagem de 75 mL L-1. Portanto, conclui-se que o produto à base de extrato da alga A. nodosum pode ser incluído ao manejo integrado de doenças em pós-colheita de citros.Research, Society and Development2021-07-28info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/1793910.33448/rsd-v10i9.17939Research, Society and Development; Vol. 10 No. 9; e32710917939Research, Society and Development; Vol. 10 Núm. 9; e32710917939Research, Society and Development; v. 10 n. 9; e327109179392525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/17939/16215Copyright (c) 2021 Maria Eduarda Ferreira Naves; Natália Moreira Mafra; Dalilla Carvalho Rezendehttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessNaves, Maria Eduarda Ferreira Mafra, Natália Moreira Rezende, Dalilla Carvalho 2021-09-12T14:28:06Zoai:ojs.pkp.sfu.ca:article/17939Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:38:10.939010Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false
