Resumo: | ABSTRACT: The bean (Phaseolus vulgaris L.) is one of the most important constituents of the diet of the population, has an excellent protein source, but their income is low due to diseases such as common bacterial blight caused by Xanthomonas axonopodis pv. phaseoli. The aim of this study is to test the influence of foliar fertilizers in disease severity. For this purpose, bean plants were grown in a greenhouse and in the vegetative stage V2 applied the treatments with foliar fertilizers CaB (calcium and boron), Mn (manganese) and Z (zinc), and control of water, bactericidal Agrimicina (50 mg i.a.L-1 ) and acibenzolar-S-methyl (75 mg i.a L-1), and three days after the pathogen was inoculated. The bacterial suspension was inoculated at a concentration of 5 x 107 UFC mL-1. At 17, 21 and 25 days after inoculation, the severity with diagrammatic scale and the data were submitted to ANOVA and Tukey test (p = 0.05) by SISVAR program. The results show reducing the severity up to 47% when compared with control when applied manganese, making it promising for research related to alternative control this pathosystem.
