Abstract

The heavy use of pesticides in banana cultivation is associated to environmental and human health degradation. Environmentally friendly alternatives for sustainable agriculture are needed to mitigate the negative impacts of chemicals. This study aims to evaluate the efficiency of biocontrols in the synthesis of bioactive secondary metabolites, mainly polyphenols. Thus, three biocontrols (Vacciplant^®, Callel^®, and Calliete^®) were applied on three cultivars of banana (Orishele, Corne, and French) for 24 h, 48 h, and 72 h and the polyphenol contents were measured. Results showed that the polyphenol contents varied in function of the incubation time and the variety of banana. The highest polyphenol contents were 170.8 and 169.47 µg/g FM and were obtained with Corne-Calliete (Co-Ca) and Corne-Vacciplant (Co-V) respectively. Biocontrols Vacciplant^® and Calliette^® showed had the best action in stimulating polyphenol production in the three cultivars of banana.
