Freqüência de ocorrência de agentes etiológicos, sintomas e origem de amostras do cafeeiro catalogados em 12 anos de clínica fitossanitária da UFLA

Abstract

The Phytossanitary Clinic of the Federal University of Lavras, situated in the south of the State of Minas Gerais has given support to coffee producers providing diagnoses of biotic and abiotic diseases, to generate subsidies to minimize losses in production of this crop. During the last twelve years, 378 samples have been analyzed. Fungi were detected in 78,6% of the samples. The major fungi found were Colletotrichum sp. (29%), Rhizoctonia solani (18%), Cercospora coffeicola (13%), Phoma sp. (13%), e Fusarium sp (11%). Other incidences were caused by phytotoxity, mineral deficiency and bad formation of the roots. Due to the location of the Phytossanitary Clinic, most of the samples came from locations of South of Minas Gerais (63%), followed by Triângulo Mineiro (12%) and Zona da Mata (10%).
