D.  aSeverity of banana leaf spot in an intercropping system in two cycles of banana Prata Anã.  c2008  aPrata Anã is the most planted banana cultivar in northern Minas Gerais, Brazil. It is however susceptible to several pathogens. This study was carried out to evaluate the disease severity of banana leaf spot in the Prata Anã cv. in the first and second cycle under six different planting systems. The randomized block experimental design was used with six treatments and four replications. In an evaluation of the severity of banana leaf spot, no disease symptoms were found on Thap Maeo and Caipira. The evolution curve of the disease indicated seasonal effects in the first and second cycles. The severity of banana leaf spot was highest soon after the regional rainy period from November to March. A comparison of the means of the evaluations indicated a reduction in disease severity from the first to the second cycle.  aAgricultura  aBiotecnologia  aGenética  aMusa sp  aMycosphaerella Musicola  aBananeira prata anã  aInterplantio  aSeveridade da doença  aSigatoka amarela1 aNIETSCHE, S.1 aPEREIRA, M.
