The main management strategy for coffee leaf rust (Hemileia vastatrix) in conilon coffee is based on the application of fungicides using a fixed schedule without considering the epidemiological aspects of the disease. In order to turn chemical control less subjective and more efficient, two systems of coffee leaf rust management were tested: 1) application of systemic fungicide based on the intensity of the disease present in each conilon clone of the "Conilon Vitria" variety, according to the disease incidence; threshold of 5 % incidence of the disease was adopted to spray the fungicide, and 2) application of systemic fungicide to the soil, followed by foliar application in the beginning of the rainy season. The experiments were performed in two municipalities of the Espirito Santo State, Nova Ven,cia e Castelo. Monthly evaluations of disease incidence were performed between September 2010 and August 2011. The results showed that chemical control of coffee leaf rust in conilon coffee should be performed differently, for each clone, of the clonal Vitoria variety. The 5 % threshold of the disease incidence was reached at different time of the coffee grower season. The strategy to apply systemic fungicide to the leaves, to control conilon leaf rust, based on the disease incidence of 5 % was more effective than soil application system. Application of systemic fungicide to the soil did not control the disease. In conclusion, monitoring the incidence of coffee leaf rust in all the clones is an important strategy to decide the appropriate time to apply fungicides.
