Citrus Variegated Chlorosis (CVC), caused by Xylella fastidiosa, causes losses of around 120 million dollars/year in Brazil. CVC is present in Brazil since 1987, even though, the relationship between disease intensity and yield losses has never been established. The objective of this study was to determine this relationship. The incidence of branches with symptoms of CVC and the asymptomatic fruit yield (asymptomatic fruit production) were evaluated during three years (2006 to 2008), in orchard located at São Paulo State. The experiment design was in factorial randomized blocks (3x2). The treatments were: no irrigation, irrigated with 50% and 100% of Crop evapotranspiration (ETc), combined with natural and artificial inoculation of X. fastidiosa. Each plot consisted of 6 plants, with 4 replication, total 144 trees (10-yr-old Natal sweet orange). The single plant method was used to quantify disease damage. For all treatments, the decrease of yield ((asymptomatic frit production) was associated with the increased of CVC incidence, described by the negative exponential model. The reductions of yield rates were similar for. |
