Resumo: | The papaya fruit rot (Phytophthora palmivora) is responsible for significant losses. To reduce diseases, especially in areas with climate and humidity favorable to pathogens, are adopted chemical methods, which sometimes increase the cost of production and cause severe environmental impacts. Alternatively, there are products, such as, phosphites of potassium and acibenzolar-S-methyl (ASM) that might be efficient on disease control and less aggressive to environment. Phosphites of K and ASM were evaluated in this study on the control effectiveness of papaya fruit rot at different dosages in preharvest and postharvest. The severity and percentage of disease control were evaluated for each treatment. For the pre-harvest treatments (applied six days before harvest), the phosphite of K [240 g L-1 K2O, 340 g L-1 P2O5 and 50 g L-1 (Reforce® + Salicylic Acid)] at 3 or 6 mL L-1significantly reduced disease severity, and, reduced fruit ripening. On postharvest application, ASM reduced disease severity. |

Porém, estas medidas podem elevar o custo da produção e causar severos impactos ambientais. Alternativamente, existem produtos como os fosfitos de potássio (K) e acibenzolar-S-metil (ASM) que podem ser eficientes no controle de doenças e menos agressivos ao ambiente. Fosfitos de K e ASM foram avaliados neste trabalho quanto à eficácia do controle da podridão de frutos de mamão ‘Sunrise Solo’ tipo exportação, cultivados no Sul da Bahia, em diferentes doses e formulações comerciais na pré e pós-colheita. Para cada tratamento foi avaliada a severidade da doença e o percentual de controle da doença, sendo também verificada a influência nas características fisioquímicas na fruta. Para os tratamentos pré-colheita, aplicados aos seis dias antes da colheita, o fosfito de K [240 g L-1 K2O, 340 g L-1 P2O5 e 50 g L-1 C7H6O3 (Reforce® + Ácido Salicílico)] a 3 ou 6 mL L-1 reduziu significativamente a doença, e influencioudiretamente no atraso da maturação da fruta. Na pós-colheita, ASM incitou redução na severidade da doença. Todos os tratamentos não alterarão as características fisioquímicas da fruta.EDUFU2018-12-14info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.ufu.br/index.php/biosciencejournal/article/view/3955010.14393/BJ-v34n6a2018-39550Bioscience Journal ; Vol. 34 No. 6 (2018): Nov./Dec.; 1522-1531Bioscience Journal ; v. 34 n. 6 (2018): Nov./Dec.; 1522-15311981-3163reponame:Bioscience journal (Online)instname:Universidade Federal de Uberlândia (UFU)instacron:UFUenghttps://seer.ufu.br/index.php/biosciencejournal/article/view/39550/24826Brazil; ContemporaryCopyright (c) 2018 Thiago Alves Santos de Oliveira, Luiz Eduardo Bassay Blum, Elizabeth Amélia Alves Duarte, Edna Dora Martins Newman Luzhttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessOliveira, Thiago Alves Santos deBlum, Luiz Eduardo BassayDuarte, Elizabeth Amélia AlvesLuz, Edna Dora Martins Newman2022-02-02T04:10:36Zoai:ojs.www.seer.ufu.br:article/39550Revistahttps://seer.ufu.br/index.php/biosciencejournalPUBhttps://seer.ufu.br/index.php/biosciencejournal/oaibiosciencej@ufu.br||1981-31631516-3725opendoar:2022-02-02T04:10:36Bioscience journal (Online) - Universidade Federal de Uberlândia (UFU)false |
