Resumo
A mancha-anular do cafeeiro, cujo agente etiológico é o Coffee ringspot virus (CoRSV), é uma doença que vem causando danos em lavouras de café nos estados de Minas Gerais e São Paulo. Os danos vão desde a desfolha acentuada, queda precoce de frutos e perda da qualidade. Neste trabalho foi realizado um estudo visando identificar a mancha-anular em fazendas de café no Oeste da Bahia, Brasil. Nos Municípios de Luís Eduardo Magalhães e São Desidério, situados no Oeste da Bahia, Brasil, foram observadas incidências de até 45,6% de plantas de café com sintomas de mancha-anular. Inoculação mecânica do material infectado em plantas indicadoras de vírus, Chenopodium quinoa, Amaranthus deflexus e Chenopodium ambrosioides, induziram sintomas típicos, confirmando a infecção pelo Coffee ringspot virus (CoRSV). Esse é o primeiro relato do CoRSV no Oeste da Bahia, indicando que esse vírus, provavelmente, está presente em todas as lavouras cafeeiras da região, estabelecidas em locais com temperaturas mais elevadas, pois são consideradas ideais para a multiplicação viral.
The coffee ringspot, whose etiologic agent is the Coffee ringspot virus (CoRSV), is a disease that has been causing damage in defoliation in coffee plantations in the states of Minas Gerais and São Paulo. The damage ranging from the defoliation accentuated, premature fall of fruits and loss of quality. This work was carried out a study to identify the stain- override in coffee farms in Western Bahia, Brazil. In Luís Eduardo Magalhães and São Desiderio counties, located in Western Bahia - Brazil, were observed incidences up to 45,6% of coffee plants with ringspot symptoms. Mechanical inoculation of infected material in indicator plants for viruses, Chenopodium ambrosioides, Amaranthus deflexus and Chenopodium quinoa induced typical symptoms confirming the infection by Coffee ringspot virus (CoRSV). This is the first record of CoRSV in Western Bahia, indicating that this virus probably is present in all coffee plantations of the region, established in places with higher temperatures, since this is a factor considered ideal for viral multiplication.
