RESUMO:
The oil palm (Elaeis guineensis Jacq.) Comes from West Africa in the Gulf of Guinea region. It was brought to Brazil in the colonial period, 17th century, by slaves and its cultivation began in Brazil in the 70's, being a tropical perennial species of African origin that best expresses its production potential under high temperature, solar radiation, high precipitation and humidity. relative air. Among the main diseases that attack this palm and other palm trees of economic importance, the Red Ring disease is one of the most severe and deadly, causing the plant to death and endangering the development of plantations in the region. Thus, the objective is to evaluate the spatial and temporal distribution of Anel Vermelho and R.Palmarum in conventional palm oil plantation in the municipality of Thailand, state of Pará, in the production area of AGROPAR Farm, belonging to AGROPALMA SA, through of data obtained monthly from a Historical series from 2011 to 2018, seeking to identify the spatial distribution pattern of this pathosystem, using Geostatistics as a tool. To evaluate the dispersion of the Red Ring and R.Palmarum will be used the presence and absence method, being (1) for the presence and (0) for absence. Thus, semivariograms will be generated and the theoretical models will be tested: Spherical, Gaussian, exponential and linear (pure nugget effect). For the spatiotemporal distribution of the red ring pathosystem a centroid of each plot will be generated and the geographic coordinates (Latitude and Longitude) will be related to the accumulated occurrences of the red ring per year and to determine the dispersion of R.Palmarum the traps will be georeferenced and related to the occurrences of this insect vector. The semivariograms obtained will be submitted to the estimated Kriging for the preparation of the Patossystem dispersion maps. Thus, the objective of this work is to evaluate the spatial and temporal distribution of the Red Ring in conventional oil palm planting in Thailand-PA
