| الوصف: | Spatial patterns of spear rot and ‘marchitez sorpresiva’ epidemics in oil palm in Surinam were analyzed using geostatistics. Semivariogram analysis generally led to linear and spherical graphs of respectively, spear rot and marchitez incidence in areas where the diseases were not yet under control. In both, spear rot and marchitez, semivariograms indicated focal development in the initial stage of the epidemics, illustrated through disease maps and described by gradient analysis. In case of spear rot, the linear model of semivariograms suggested a disease dispersal with a spreading mechanism which operated over long distances within sampled area. Disease dispersal in marchitez was localized, suggesting tree to tree transmission within the range of the spherical semivariograms. |
