Abstract: Avaliou-se o progresso da cercosporiose em cafeeiros sob sistemas de produção orgânico e convencional no município de Santo Antônio do Amparo, MG, entre novembro/2003 e novembro/2005. As lavouras, que são vizinhas, encontravam-se sob condições similares de clima, solo e relevo e eram formadas por cafeeiros cv. Acaiá MG-474-19, de dez anos. A doença foi mais intensa no sistema de produção convencional, cuja média de dois anos consecutivos de avaliações demonstrou área abaixo da curva de progresso da cercosporio… Show more

“…According to Santos, Souza, Pozza, Miranda, Barreto, et al. (), Santos, Souza, Pozza, Miranda, Carvalho, et al. (), defoliation intensified by disease reduces photosynthetic capacity, vegetative growth and fruit size during the coffee life cycle.…”

“…(), defoliation intensified by disease reduces photosynthetic capacity, vegetative growth and fruit size during the coffee life cycle. This intense leaf fall due to the previous cycle of disease reduces the number of nodes in the branches, damaging the formation of flower buds that would produce fruits and thus reducing the production capacity in next harvest season (Santos, Souza, Pozza, Miranda, Barreto, et al., ; Santos, Souza, Pozza, Miranda, Carvalho, et al., ).…”

“…In an experiment with coffee seedlings grown in pots, Pozza et al (2001) showed that supplying bovine manure to coffee trees, as well as other types of fertiliser reduced the severity of brown-eye leaf spot. Santos et al (2008) compared the incidence of brown-eye spot on ten-year old coffee in neighbouring plots that were managed either conventionally using inorganic fertiliser applications, or by organic methods in which only organic amendments were applied to the soil. In a period of two consecutive years, disease incidence was higher in the plot under conventional management (28% and 29%) than in the plot managed using organic methods (9% and 12%), although higher berry yields were obtained in the conventionally managed plots.…”
