Summary

A presente pesquisa teve como objetivo avaliar a incidência de Hemileia vastatrix (ferrugem) e Cercospora coffeicola (cercosporiose) em agroecossistemas cafeeiros conduzidos sob manejo convencional, organo-mineral e orgânico no município de Poço-Fundo, sul de Minas Gerais. Para tanto, selecionou-se uma propriedade cafeeira que possuía os três sistemas de manejo evidenciados. As avaliações para determinação da incidência da ferrugem e da cercosporiose do cafeeiro foram realizadas mensalmente, durante um ano (dez/07 a nov/08). Coletaram-se 10 folhas do 3º ou 4º par em todos os lados da planta, sendo amostrados 20 cafeeiros por agroecossistema, tomados aleatoriamente por meio de caminhamento em zigue-zague nos agroecossistemas, totalizando 200 folhas coletadas em cada sistema. A maior incidência da ferrugem no agroecossistema convencional ocorreu em agosto, atingindo índice de 15% e a cercosporiose alcançou 38,5% de incidência em julho. Os agroecossistemas organo-mineral e orgânico apresentaram elevados níveis de ataque da ferrugem e cercosporiose, alcançando índices extremos de incidência a partir do mês de julho, ultrapassando 80% de incidência de ferrugem e 54,5% de cercosporiose.

Summary translation

This study aimed to evaluate the incidence of Hemileia vastatrix and Cercospora coffeicola conducted in coffee agroecosystems under conventional, organic-mineral and organic managements in the municipality of Poço Fundo, south of Minas Gerais, Brazil. To this end, it was selected a coffee farm with this three management systems. Sampling of leaves randomly taken to determine the incidence of coffee rust and brown eye spot were in middle third of each plant. Ten leaves were collected from third or fourth on all sides of the plant, being sampled by twenty coffee agroecosystem, totaling two thousand sheets collected from each system. The evaluations were performed monthly during one year (december, 2007 to november, 2008). The highest incidence of coffee rust in conventional agroecosystem occurred in August, reaching rates of 15% and brown eye spot incidence reached 38.5% in July, highest peak of the disease in this system. The agroecosystems organic-mineral and organic suffered high levels of attack by the coffee rust and brown eye spot, reaching extremes of incidence rates from the month of July, surpassing 80% incidence of rust and 54.5% of brown eye spot.
