Abstract
Rice plant as staple food especially in tropical regions. One of the major problems encountered by Indonesian rice farmer is the pest and diseases infestation, causing loss of potential yield. Yield lost in Indonesia was reported annually shows more intense. The intensive pest and diseases attack on young rice plant forced farmers to invest more on plant protection measures. Farmers sometimes unaware of the symptoms of pest and diseases presence until severe lost occurred. This research aimed to analyze the pest and disease attack and dispersion on the rice field during the planting season. The method using spatial analysis to map and determine the spreading pattern of certain disease spread over the farmland. Four type of pest attack patterns analyzed i.e. rice bug, brown planthopper, rice leaf roller and stem borer. The result shows that the rice bug, brown planthopper and leaf roller have smaller spreading patterns whole the stem borer have wider spreading pattern.
