The objective of this research was to evaluate the effect of organic fertilization on the sigatoka development. The treatments tested consisted of soil (S) and foliar applications (F): T1- Control, T2- biofertilizer Geobacter (F), T3- poultry manure (S), T4- biofertilizer ?Supermagro? (F), T5- silicate clay Rocksil (F), T6- rock powder (S), T7- poultry manure (S) + rock powder (S) + biofertilizer ?Supermagro? (F), T8- poultry manure (S) + rock powder (S), T9- poultry manure (S) + biofertilizer Geobacter (F) and T10- biofertilizer ?Supermagro? (F) + biofertilizer Geobacter (F). Disease was quantified by determining the gross sum and leaf emergence in five plants per plot. Disease curves showed that fertilization usually reduces gross sum of Sigatoka, specially Poultry manure (T3), rock powder (T6) and biofertilizer Supermagro (T4), but biofertilizer Geobacter (T8) and silicate clay Rocksil (T5) did not differ from the control (T1). Values of AUPDC confirmed these considerations with the disease curves.  aBanana  aBiofertilizer  aRock dust  aSigatoka  tIn: REUNIAO INTERNACIONAL ACORBAT, 19., 2010, Medellin. Proceedings...
