摘要: An experimental field study was carried out in Belem, Para, Brazil, order to monitor the evolution of two diseases grafted and non-grafted plants: 1) amount cupuacuzeiro (Theobroma grandiflorum) sprouts flowers with symptoms witches' broom 2) presence basidiocarps pathogen Crinipellis perniciosa. Epidemiological models (logistic, Gompertz, logistic + Gompertz Gompertz) were fit biannual disease progress curves (1993 1994 for incidence basidiocarp production sprouts) annual (1994) on produced flowers. The sum equations well data model data. appearance generally associated dry period, whereas occurred during rainy period. highest from July October most fungus fruiting bodies detected May-July.
