Conteúdo:

The scab (Cladosporium spp.) is a harmful disease of the passion fruit vine
(Passiflora edulis f. flavicarpa). It can occur in all aerial parts of the plant,
including leaves, little branches, flowers and fruits. It is a typical young tissue
illness causing clorosis in the leaves and can lead to the defoliation of the
plant. The aim of this study was to evaluate the progress of the scabon the
Gigante Amarelo, Sol do Cerrado, Ouro Vermelho e Rubi varieties of passion
fruit on brasilian cerrado. Were installed four experimental plots containing
three plants of each variety, spaced 2.0 × 4.0 meters in cordon training system.
From the flowering were performed 15 evaluations for the incidence and
severity of the scab on the leaves of one branch of each plant, with an interval
of seven days between them. Were calculated the area under disease incidence
(AUIPC) and under disease severity (AUSPC) progress curve, and was set a
model for disease progress over the time. The varieties showed no significant
differences between the AUIPC and AUSPC. The monomolecular model
fitted better to the incidence and severity progress curves for all varieties and
showed the highest coefficients of determination and lower residual mean
squares.
