Resumo: The appropriate management of leaf diseases, such as rust and cercospora of the coffee plant, has become extremely important to the production of good quality coffee. In this context, the knowledge of technical procedures and phytosanitary products become extremely important, as well as the effect caused by them in the coffee quality. The objective of this work was to verify the influence of different methods of controlling fungal diseases in coffee plant on the grain quality of parchment and floater coffee. Trials were carried out in 2002/2003 and 2003/2004. The experimental design was the randomized complete block design subdivided into plots, using four replications, in a 2 x 3 x 2 factorial structure, involving two harvests, three fungicide treatments (Ópera®systemic fungicide, Cobox® cupric fungicide, and non-treated control), and two kinds of processing, parchment and floaters. The evaluation of the quality of the grains was performed through chemical analyses: titrable acidity, pH, leaching of potassium, and electrical conductivity. The results showed that the fungicide treatments just affect the leaching of potassium in floater coffee, in which Cobox® presented superior effect. In both processing methods studied the second year presented better electrical conductivity and better leaching of potassium in floater coffee. In the first year the parchment coffee presented superior effect for the titrable acidity.

Nesse sentido, torna-se de extrema importância o conhecimento dos procedimentos técnicos e de produtos fitossanitários, bem como o efeito exercido pelos mesmos na qualidade do café. Objetivou-se, com este trabalho, estudar a qualidade dos grãos de café cereja descascado e bóia procedentes de tratamentos fungicidas, em duas safras agrícolas. Foram conduzidos ensaios nos anos agrícolas 2002/03 e 2003/04. O delineamento utilizado foi o inteiramente casualizado com parcelas subdivididas, utilizando-se quatro repetições, em esquema fatorial 2 x 3 x 2, compreendendo duas safras, três tratamentos fungicidas (fungicida sistêmico, nome comercial Ópera®, fungicida de contato, nome comercial Cobox®, e testemunha não tratada com fungicidas) e dois tipos de processamento, cereja descascado e bóia. As avaliações da qualidade dos grãos foram realizadas por meio das análises químicas: acidez titulável, pH, lixiviação de potássio e condutividade elétrica. Os resultados indicaram que os tratamentos fungicidas afetaram apenas a lixiviação de potássio para o café bóia, no qual o Cobox® apresentou menor lixiviação comparado aos demais. Em ambos os processamentos estudados, o segundo ano de ensaio apresentou maior condutividade elétrica, e quando considerado o café bóia, maior lixiviação de potássio. O resultados apontam ainda que, no primeiro ano de ensaio o café cereja descascado apresentou efeito superior para a acidez titulável.Editora da Universidade Federal de Lavras2009-01-012015-04-30T13:35:33Z2015-04-30T13:35:33Z2015-04-30info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articletext/htmlhttp://www.scielo.br/scielo.php?script=sci_arttext&pid=S1413-70542009000700038ABRAHAO, A.
