Resumo: | The objective of this study was to analyze the efficiency of the fungicide azoxystrobin in conjunction with mancozeb and chlorotalonyl multisites after the simulation of rainfall in different periods to control the target spot in soybean. The experiment was carried out at the company Fortgreen Comercial Agricola S. A in the municipality of Paiçandu-PR. It was planted 5 seeds per pots of two kg, with the mixture of soil and sand in the proportion of 3:1, without any type of fertilization or chemical treatment. The experiment was carried out in a completely randomized design with 20 treatments and 5 replications and the applications were CO-₂, with 40 pressure bar in the cone-type nozzle, according to the recommended commercial dosages for the control Target spot. The fungicides azoxystrobin alone, azoxystrobin + mancozeb and azoxystrobin + chlorotalonil were used. After application, they were subjected to rain simulations lasting 15 minutes at an intensity of 1mm / min at different times 0.5; 1; 2 hours after application. Disease severity in the inoculated trifolium was analyzed and the Area Below the Disease Progress Curve (AACPD) was verified. The use of chlorotalonil fungicide without association with rain after application caused phytotoxicity in soybean crop. The application of azoxystrobin + mancozeb and azoxystrobin + chlorotalonil according to AACPD obtained significantly different results, whereas Mancozebe in combination with the systemic showed better control in disease progression. Rain was a factor that interfered with this efficiency, and wetness 0.5 hour after the application of multisite mancozenbe + azoxystrobin was a factor that interfered with the increase of severity. |

O experimento foi realizado na empresa Fortgreen Comercial Agrícola S.A no município de Paiçandu – PR. Foi semeado 5 sementes por vasos de 2 kg, com a mistura de solo e areia na proporção de 3:1, sem nenhum tipo de adubação ou tratamento químico. O experimento foi conduzido em Delineamento Inteiramente Casualizado (DIC), com 20 tratamentos e 5 repetições e as aplicações foram do tipo CO₂, com 40 bar de pressão no bico tipo cone, conforme as dosagens comerciais recomendadas para o controle de mancha-alvo. Utilizou-se os fungicidas azoxistrobina de forma isolada, azoxistrobina + mancozeb e azoxistrobina + clorotalonil. Após a aplicação foram submetidos a simulações de chuva com duração de 15 minutos numa intensidade de 1mm/min, em diferentes tempos 0,5; 1; 2 horas após a aplicação. Foi analisado a severidade da doença no trifólio inoculado e verificada a Área Abaixo da Curva de Progresso da Doença (AACPD). O uso do fungicida clorotalonil sem associação com chuva após a aplicação causou fitotoxicidade na cultura da soja. A aplicação de azoxistrobina + mancozeb e azoxistrobina + clorotalonil de acordo a AACPD obtiveram resultados significativamente diferentes, sendo que o Mancozebe em associação com o sistêmico mostrou melhor controle no progresso da doença. A chuva foi um fator que interferiu nessa eficiência, sendo que o molhamento 0,5 hora após a aplicação do multissítio mancozenbe+ azoxistrobina foi um fator que interferiu no aumento da severidade.UNIVERSIDADE CESUMARBrasilUNICESUMARZULIANI, Aline Maria Orbolato GonçalvesMARQUES, GuilhermeTERNISKI, Wallison José2020-01-27T13:10:48Z2020-01-27T13:10:48Z2019-12-05info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfhttp://rdu.unicesumar.edu.br/handle/123456789/4637porinfo:eu-repo/semantics/openAccessreponame:Repositório Digital Unicesumarinstname:Centro Universitário de Maringá (UNICESUMAR)instacron:UniCesumar2021-06-25T17:46:44Zoai:rdu.unicesumar.edu.br:123456789/4637Repositório InstitucionalPRIhttp://rdu.unicesumar.edu.br/oai/requestopendoar:2021-06-25T17:46:44Repositório Digital Unicesumar - Centro Universitário de Maringá (UNICESUMAR)false |
