Resumo: The objective of this paper was to evaluate the control of soybean rust using the protective fungicide Mancozeb associated with curative fungicides. The trial was conducted in the field, using a randomized block design, with five replications. The evaluated treatments were: association of protective fungicide (Mancozeb 1,500 g a.i. ha-1) with curative fungicides (Picoxystrobin 66 g a.i. ha-1 + Cyproconazole 26 g a.i. ha-1 and Azoxystrobin 100 g a.i, ha-1 + Benzovindiflupyr 50 g a.i. ha-1), protective fungicide without association, curative fungicides without association and a control treatment, without control. The disease incidence, control and phytotoxicity of the fungicides, that were applied at the R1, R3 and R5 stages of the crop, were evaluated. Grain yield and yield reduction resulting from disease attack were evaluated. Mancozeb alone, applied 3x, provided efficiency similar to its use and in association with other fungicides. The association of Mancozeb with mesostemic and curative fungicides provided an increase in disease control. Mancozeb, as the only form of disease control, applied once during the cycle, did not promote sufficient disease control, which resulted in a 35.80% drop in productivity.

O ensaio foi conduzido a campo, utilizando delineamento em blocos casualizados, com cinco repetições. Os tratamentos avaliados foram: associação do fungicida protetor (Mancozebe 1.500 g i.a. ha-1) com fungicidas curativos (Picoxistrobina 66 g i.a. ha-1 + Ciproconazole 26 g i.a. ha-1 e Azoxistrobina 100 g i.a. ha-1 + Benzovindiflupir 50 g i.a. ha-1), fungicida protetor sem associação, fungicidas curativos sem associação e um tratamento testemunha, sem controle. Avaliou-se a incidência da doença, o controle e a fitotoxidade dos fungicidas que foram aplicados no estádios R1, R3 e R5 da cultura. Avaliou-se a produtividade de grãos e a redução na produtividade resultante do ataque da doença. O Mancozebe de forma isolada, aplicado 3x proporcionou eficiência semelhante ao seu uso e em associação com os demais fungicidas. A associação do Mancozebe com os fungicidas mesostêmicos e curativos proporcionou incremento no controle da doença. O Mancozebe como única forma de controle da doença, aplicado 1x durante o ciclo, não promoveu controle suficiente da doença, que provou queda de 35,80% na produtividade.Universidade Federal Rural da Amazônia/UFRA2023-12-20info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionArtigo científicoapplication/pdfhttps://ajaes.ufra.edu.br/index.php/ajaes/article/view/3604Amazonian Journal of Agricultural Sciences Journal of Agricultural and Environmental Sciences; Vol 66 (2023): RCA AJAES; 1-11Revista de Ciências Agrárias Amazonian Journal of Agricultural and Environmental Sciences; v. 66 (2023): RCA AJAES; 1-112177-87601517-591Xreponame:Revista de Ciências Agrárias (Belém.
