Phosphites for the control of anthracnose in common bean

Abstract: -The objective of this work was to evaluate the effect of phosphites in the protection of common bean (Phaseolus vulgaris) against anthracnose. Different phosphite formulations were evaluated by quantifying peroxidase and polyphenol oxidase activity, total phenols, and lignin content. The treatments consisted of sprayings, in the V4, R5, and R7 stages, with: the K, Zn, Mn, K+Mn, K+salicyclic acid, and Cu phosphites; salicylic acid; acibenzolar-S-methyl; the fungicide azoxystrobin; besides a control, without sp… Show more

“…Several studies have also demonstrated the efficiency of phosphites in the inhibition of pathogen growth, such as Alternaria alternata (Reuveni, Sheglov, & Cohen, 2003), Penicillium expansum (Amiri & Bompeix, 2011), Venturia pirina (Percival, Noviss, & Haynes, 2009), Monilinia fructicola (Moreira & May-De-Mio, 2009) and oomycetes in different crops (McDonald et al, 2001;Silva, Santos, Dalla Pria, & May-de-Mio, 2011). The disease control provided by phosphites seems to be the result of the resistance inducer effect of these products (Dalio et al, 2012;Daniel & Guest, 2006;Eshraghi et al, 2011;Gadaga, Abreu, Resende, & Ribeiro Júnior, 2017; and/or their direct effect on pathogens (Costa et al, 2014;Dalio et al, 2012;King et al, 2010;Nojosa et al, 2009) Resende, Medeiros, Zhang, & Paré, 2009;Santos et al, 2007).…”

“…Estes resultados contrariam os obtidos por Gadaga et al (2017), onde os autores aplicaram diferentes formulações de fosfito e avaliaram a severidade da antracnose em feijão na casa de vegetação, tendo como resultado que todos os produtos aplicados ocasionaram redução da doença e menores AACPD que a testemunha. Hennipman et al (2019) O ASM é capaz de ativar defesas das plantas, fazendo com que a planta ative mecanismos de prevenção contra o ataque de determinados patógenos.…”

“…Porém, o uso de fungicidas pode causar contaminação do solo, ambiental e humana, enquanto que a resistência das plantas nas cultivares pode ser quebrada por diferentes agentes patogênicos. Essas preocupações estimulam o desenvolvimento de novas tecnologias (GADAGA et al, 2017).…”

“…Na cultura do feijão comum (Phaseolus vulgaris), a utilização de fosfitos reduziu a severidade da antracnose de acordo com trabalho realizado por GADAGA et al (2017), segundo estes autores, os fosfitos utilizados podem ser considerados um método alternativo de controle. Já para BUFFARA et al (2013), o uso de fosfito de potássio em folhas de videira em pré e pós-infecção pode reduzir o ataque de Phakopsora euvitis em aproximadamente 50% quando comparado ao tratamento com tebuconazol.…”
