Use of Ecolife® and Acibenzolar-S-metil (ASM) on the control of antracnosis in banana post-harvest

The aim of this work was to evaluate the effects of ASM and Ecolife on the control of post-harvest antracnosis in banana. Banana fruits of Maçã, Prata, Pacovan and Figo varieties, at intermediate stage of maturation, were immersed in solutions of ASM and Ecolife and inoculated with Colletotrichum musae A completely randomized design was used, at a factorial scheme 4x2 (four varieties x two products) with four replicates. The presented results demonstrated the susceptibility of the fruits to the disease, mainly Maça variety with lesion of 17,99 mm. It was demosntrated the effectiveness of products at concentrations of 5ml. L-1 (Ecolife) and 0.50g. L-1 (ASM) on antracnosis control. The Figo variety presented the smallest injuries when treated with Ecolife (5.79 mm). Regarding ASM effects, Prata variety demonstrated the best performance, with 5.62 mm of injuries diameter. Throughout the maturation of the fruits the disease severity was declined in all varieties, except in the control treatment, where injuries continued growing until reaching the pulp.
