Resumo -A pimenta-do-reino é o condimento mais comercializado no mundo e uma cultura de importância sócio econômico regional. A fusariose é uma doença causada pelo fungo Fusarium solani f. sp. piperis (Nectria haematococca f. sp. piperis) e tornou-se o principal problema fitossanitário da pipericultura nacional. Pouco se conhece da dinâmica de suas interações com o ambiente do solo, hospedeiro e estabelecimento da doença. A geoestatística possui ferramentas que permitem conhecer e visualizar a variabilidade espacial, além de correlacionar e associar o mesmo aos fenômenos em estudo, contribuindo para o entendimento das interações patógeno-ambiente-hospedeiro. Sendo assim, o objetivo foi pesquisar e aplicar métodos da geoestatística para compreender a distribuição espacial da fusariose em pimenta-doreino. O experimento foi conduzido no período de 2010 a 2011, na Região Norte do Estado do Espírito Santo. A geoestatistica foi utilizada para constar a dependência espacial das variáveis em estudo, para isso implantou-se uma malha amostral regular de 12.000m 2 e a incidência da doença foi avaliada ao longo de 150 dias. Os mapas da distribuição da doença ao longo do tempo demostraram foco inicial nas bordas da lavoura e os modelos teóricos ajustados dos variogramas, representaram os diferentes estágios da epidemia de fusariose na lavoura de pimenta-do-reino.Palavras-chave: geoestatística; Fusarium solani f. sp. piperis; Piper nigrum L. Spatial and Temporal Distribution of fusarium wilt in Black Pepper CropAbstract -The Fusarium wilt is a disease caused by the fungus Fusarium solani f. sp. piperis (Nectria haematococca f. sp. piperis) and became the main disease problem of national pepper crop. Few reports is known about the dynamics of their interactions with the soil environment, host and disease establishment. Geostatistics provides tools that allow understanding and visualizing the spatial variability, to correlate and to associate it with the phenomena under study, contributing to the understanding of interactions between pathogen-host-environment. Therefore, the present experiment was to investigate and to implement geostatistics methods to understand the spatial distribution of fusarium wilt in black pepper. The experiment was conducted from 2010 to 2011 in the North of Espirito Santo State. Geostatistics was used to include the spatial dependence of the variables under study, for it was implemented a regular sampling grid (12.000m 2 ) and the disease incidence was evaluated over 150 days, a total of seven evaluations. In the last evaluation were carried out soil samples for chemical,, physical and textural analysis. The maps of disease distribution over time demonstrated an initial focus on the edges of the crop and theoretical models of the adjusted variogram represented the different stages of the epidemic of Fusarium in the black pepper crop.Key words: geostatistics; Fusarium solani f. sp. piperis; Piper nigrum L.
