In this sense, studies are needed considering the use of biological products, as sources of alternative controls, which can be used in an integrated manner with fungicides in the management of leaf diseases in soybean crops. The objective of this work is to evaluate the potential of a commercial product based on Bacillusin the control of leaf diseases at the end of the cycle -DFC (anthracnose, septoriosis, cercosporiosis and target spot). The work was carried out at the experimental station of the Federal Technological University of Paraná (UTFPR) Campus Dois Vizinhos, during 2020 and 2021. There were 7 treatments, consisting of: 1-control (without applications); 2-treatment with systemic fungicides (Epoxiconazole, Fluxapiroxade, Piraclostrobina and Bixafem, Protioconazole, Trifloxistrobina); 3-multisite fungicide (Mancozeb and Clorotalonil); 4-systemic + multisite; 5-Bacillus based product (B. subtilis; B. pumilus, B. amyloliquefaciens); 6-two initial applications of Bacillus and two subsequent applications of systemic fungicide; 7-associated application of systemic fungicide and Bacillus. For all treatments, there were four applications, the first being carried out at the phenological stage V5 (5 true leaves) and the others at 15-day intervals. The experimental design used was that of randomized blocks, in 4 replicates with plots of 24m2. The variables evaluated were the incidence and severity of end-of-cycle diseases, constituting the Area Below the Disease Progress Curve and productivity. The results showed that the use of the commercial product based on B. subtilis; B. pumilus, B. amyloliquefaciens has action on end-of-cycle diseases, and when positioned only Bacillus reduced the severity of DFC, differing from the control, however with less efficiency than fungicides. However, when two initial applications and two fungicides were carried out, or in the four associated applications, it showed good performance in reducing diseases and increasing productivity. A soja (Glycine max), é a principal cultura agrícola do Brasil, e vem nos últimos anos demandando adequações no cultivo para um processo de produção sustentável. Nesse sentido, são necessários estudos considerando o uso de produtos biológicos, como fontes de controles alternativos, que possam ser utilizados de forma integrada com fungicidas no manejo de doenças foliares na cultura da soja. O objetivo do presente trabalho é avaliar o potencial de produto comercial a base de Bacillus no controle de doenças foliares de final de ciclo - DFC (antracnose, septoriose, cercosporiose e mancha alvo). O trabalho foi realizado na estação experimental da Universidade Tecnológica Federal do Paraná (UTFPR) Campus Dois Vizinhos, durante o ano de 2020 e 2021. Foram 7 tratamentos, constituídos sendo: 1-testemunha (sem aplicações); 2-tratamento com fungicidas sistêmicos (Epoxiconazol, Fluxapiroxade, Piraclostrobina e Bixafem, Protioconazol, Trifloxistrobina3 -fungicida multissítios (Mancozeb e Clorotalonil); 4-sistêmico + multissítios; 5-produto a base de Bacillus (B. subtilis; B. pumilus, B. amyloliquefaciens); 6-duas aplicações inicial de Bacillus e duas posteriores de fungicidas sistêmicos; 7-aplicação associada de fungicidas sistêmico e Bacillus. Para todos os tratamentos foram quatro aplicações, sendo a primeira realizada no estádio fenológico V5 (5 folhas verdadeiras) e as demais com intervalos de 15 dias. O delineamento experimental utilizado foi o de blocos ao acaso, em 4 repetições com parcelas de 24m2. As variáveis avaliadas foram a incidência e severidade das doenças de final de ciclo, constituindo a Área Abaixo da Curva de Progresso de Doença (AACPD), e produtividade. Os resultados demonstraram que o uso do produto comercial a base de B. subtilis; B. pumilus, B. amyloliquefaciens possui ação sobre doenças de final de ciclo, sendo que quando posicionado somente os Bacillus reduziu a severidade de DFC, diferindo da testemunha, no entanto com eficiência inferior aos fungicidas. No entanto, quando foram realizadas duas aplicações iniciais e duas de fungicidas, ou então, nas quatro aplicações associadas apresentou boa performance na redução de doenças e acréscimo em produtividade. 2022-08-15T18:41:06Z 2022-08-15T18:41:06Z 2021-04-27 bachelorThesis RISSATO, Renan Broti.
