Impact on yield depends on the disease involved, the crop species . Interest has arisen lately in model validation through the quantification of the economic costs of false positives and false negatives, where disease prevention measures may be used when unnecessary or not applied when needed respectively. IR50 and C22 at Cavinti, Philippines, were generated, using weather factors identified by the WINDOW PANE program to be highly correlated with disease. A stable, nutritious food supply will be needed to lift people out of poverty and improve health outcomes. Plant Dis. The simplest model, which was also a good fit, included only the 10-day cumulative number of hours of leaf wetness. Plant disease outbreaks are increasing and threaten food security for the vulnerable in many areas of the world. The early-stage diagnosis of plant diseases like viruses, bacteria, fungi, etc. In this paper, we outline common methodologies that are used to quantify and model spatio-temporal dynamics of plant diseases, with emphasis on developing temporal forecast models and on quantifying spatial patterns. Regulatory methods, 23. To use generic and modular simulation models for predicting diseases establishment based on weather data and to implement a disease warning system using simulation models and the near real-time weather data acquisition system plus local specific weather forecast. Many plant disease forecast models or decision support systems are driven by weather variables reflecting conditions favouring the plant pathogen at critical crop developmental stages (e.g. This disease decreases plant growth up to 65-75 %. forecast models do not (Seem, 2001). developing plant disease forecasting systems is presented, followed by an introduction to how using rainfall and temperature may be applicable for developing a forecast model, and finally, four case studies are presented that Forecasting of plant diseases means predicting for the occurrence of plant disease in a specified area ahead of time, so that suitable control measures can be undertaken in advance to avoid losses..
