Avaliação da eficiência de diferentes formas de controle da queima das folhas do inhame causada por Curvularia eragrostides

Abstract: RESUMO A queima das folhas do inhame, causada por Curvularia eragrostides pode comprometer a produção do inhame (Dioscorea spp.), uma cultura de extrema importância para a região Nordeste do Brasil. O uso de produtos naturais vem sendo utilizados com eficiência no controle de doenças de plantas por sua ação fungitóxica ou pela presença de compostos eliciadores, reduzindo o uso de defensivos agrícolas. O objetivo deste trabalho foi avaliar o efeito de diferentes formas de controle da queima das folhas do inhame… Show more

“…The reduction in PAL activity in plants whose seeds were soaked in Ecolife ® can be explained by the increase in the ascorbic acid concentration (Carvalho et al, 2021), which is a non-enzymatic antioxidant, enzymes cofactor involved in photosynthesis, hormones biosynthesis such as ethylene and antioxidant regeneration under adverse conditions, inhibiting the abscisic acid and ROS accumulation (Yanwen et al, 2019). In addition, Ecolife ® has in its basic composition, polyphenols, flavonoids, phytoalexins and organic acids; and, being one of the PAL functions in plant metabolism is to act in the metabolic path-way of phenolic compounds synthesis (Jiang and Joyce, 2003;Gomes and Nascimento, 2018), possibly there was less enzyme activity, due to the formulation of the elicitor that helps supply the plant's needs.…”
