Banana is the most important fruit in organic production for the State of Santa Catarina, Brazil. These organic
systems are managed in semi extractive way with very few management practices in the production areas. The
objective of this research was to evaluate the effect of organic fertilization on the sigatoka development and
leaf emergence in two year period. Treatments consisted of soil (S) and foliar applications (F): T1- Control
(no application), T2- poultry manure (S), T3- rock powder (S), T4- biofertilizer ?Supermagro? (F), T5- poultry
manure (S) + rock powder (S) + biofertilizer (F). The development of the plants was carried out every two
weeks by foliar emission (mean and sum total leaves emitted in the period) with the help of Brun scale. Disease
was quantified by the determination of gross sum on the leaves 2,3 and 4 in intervals of 15 days. Disease data
was used to calculate the area under disease progress curve (AUPDC). The study design was a randomized
block with three blocks and five treatments. Data were subjected to analysis of variance (5% error). In spring
and summer, the poultry litter, rock powder, biofertilizer and fertilizer increased the average leaf emission by
17%; 10%; 17% and 14%, respectively, compared to the control. Disease was reduced by 28% with mixture
of fertlizers, 18% with poultry manure, 13% with biofertilizer and 10% with rock powder when compared with
control. Disease curves confirmed that fertilization usually reduce Yellow Sigatoka. Fertilization is an
important practice to promote the growth and the disease control in organic systems. Sponsors: Acafruta e SC
