Abstract: RESUMOEste trabalho objetivou avaliar o potencial do ácido jasmônico (AJ), quitosana desacetilada (QUI), silicato de potássio (SP), acibenzolar-S-metil (ASM), Ethefon (ET) e fosfito de potássio (FP) na redução da severidade da brusone do trigo. O fungicida tebuconazole (TE) e a água destilada (AD) foram utilizados como tratamentos controle. Plantas das cultivares BR 23, BH 1146 e BRS 208 foram pulverizadas com AJ, QUI, SP, ASM, ET, FP, TE e AD 24 h antes da inoculação com Pyricularia grisea. Avaliou-se o perío… Show more

“…In Brazil, Bolivia, and Paraguay wheat blast is considered a difficult disease to control. A combination of factors such as high temperatures, heavy rainfall, long and frequent leaf wetness, high diversity in MoT virulence, lack of effective blast resistance, and poor fungicide coverage, timing, and/or efficacy has favored disease outbreaks in some regions, especially in the tropics (Cruz et al 2011;Cruz and Valent 2017;Goulart 2005;Goulart et al 2007;Urashima et al 2004). In addition, the poor knowledge of ecological and epidemiological factors affecting wheat blast epidemics makes management of this disease a challenging task (Cruz and Valent 2017).…”

“…Another compound that has shown potential in priming plant defence is chitosan (CH), a natural compound derived from chitin, found in arthropod exoskeletons. Even though the application of elicitors such as JA to prime plants against herbivores has become common, it is generally used in foliar treatments (da Cruz et al, 2011;Soler et al, 2012;Li et al, 2013;War et al, 2014). It has been proven to be effective in the control of insects in feeding assays (Zhang et al, 2003;Badawy et al, 2005;Rabea et al, 2005;Badawy & El-Aswad, 2012;Zeng et al, 2012).…”

However, in large areas, this is an expensive and less practical method to enhance plant defence.…”

“…O controle da brusone tem sido realizado por meio do tratamento químico de sementes, do uso de variedades resistentes e da aplicação de fungicidas (GOULART, 1991;CRUZ et al, 2011;ROCHA et al, 2014;OLIVEIRA et al, 2015 (UCHÔA et al, 2011;FREITAS et al, 2015;FREITAS et al, 2017 14, 61 -17,46 17,46 -19,02 19,02 -19,88 19,88 -20,35 20,35 -20,61 20,61 -21,08 21,08 -21,93 21,93 -23,5 .…”
