Common bean (Phaseolus vulgaris L.) is among the main crops of national agriculture and can be affected by several diseases. Aiming to develop alternative control methods to chemical control, it was verified the potential of the aqueous extract (AE) from Lentinula edodes in controlling common bean diseases and inducing resistance by the activation of defense enzymes such as peroxidase, catalase and polyphenoloxidase, in addition to evaluating production components. The field experiment consisted of 0, 5%, 10% or 20% acibenzolar-S-methyl (ASM) and fungicide pyraclostrobin treatments as standard treatments. AE was effective in controlling anthracnose at 1% and 5% doses. The activity of all evaluated enzymes was higher at 12 and 24 hours after application of the treatments, with a concentration of 20% standing out. AE at this same dose increased the number of beans per pod and also yield. The aqueous extract of Lentinula edodes at a concentration of 20% is effective in inducing resistance, increasing enzyme levels and increasing yield.
Agradeço à Deus e Nossa Senhora, por serem meus alicerces e protetores nessa caminhada. Por intercederem sempre pela minha felicidade. Aos meus pais e irmãs, pelo apoio incondicional, incentivo e amor durante todos os momentos. Ao Conselho Nacional de Desenvolvimento Científico e Tecnológico, pela bolsa de mestrado concedida. Ao Departamento de Fitopatologia da ESALQ-USP, todos os professores, pelos ensinamentos durante esses dois anos. Ao Prof. Dr. Sérgio Florentino Pascholati, pela paciência, orientação e confiança. À Dra. Maria Heloísa Duarte de Moraes, agradeço pelo carinho, dedicação, paciência e orientação desde o nosso primeiro contato.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
