Abstract: Coffee ringspot has been known in Brazil since 1935, when it was considered of no importance for coffee growers. However, during the last few years it has seemed to be spreading rapidly. It was only in 1995, when it caused great yield losses, that virologists observed a high incidence of coffee ringspot virus in several coffee fields in Minas Gerais State. In some specific areas, 100% of the plants were infected. Other fields showed severe leaf and fruit drop, causing up to 50% yield reduction per plant and ~20% reduction in total field production. It is suggested that the probable cause of this rapid change in coffee ringspot virus epidemiology in Brazil could be an increasing vector population (Brevipalpus phoenicis) caused by the new control measures used against other pathogens like Hemileia vastatrix. This disease needs to be investigated better to establish new and effective measures for its control.
