The goal is to establish a real-time, GIS database network to detect, diagnose, report, monitor, map (temporally and spatially), and predict the spread of new and emerging plant diseases and pests. We can use mitigation strategies to help to pinpoint and stop plant pandemics; modelling and forecasting disease spread are critical elements of this. Plant Disease Forcasting - Meaning, advantages, methods in forecasting and examples Disease Forecasting 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. One of such key concept of plant pathology is The Disease Cycle. 2017 Plant Disease Forecast Brian D.

Forecast models that generate accurate predictions of complex disease systems are now on the horizon. INTRODUCTION • Forecasting of plant diseases means predicting for the occurrence of plant disease in a specified area ahead of time, so that suitable measures can be undertaken in advance to avoid losses. It usually coincides with the life cycle of the pathogen with a correlation to its host and the environment. d. Plant pathology Most plant diseases are caused by fungi e. Medical importance (1) 50-100 species recognized human pathogens (2) Most prefer to be free-living saprophytes; and only accidentally become pathogens (3) To be pathogenic, they must tolerate the temperature of the host site and possess enzymatic system that allows them to understanding how plant diseases develop as well as the various methods used for control.

Plant disease forecasting is a management system used to predict the occurrence or change in severity of plant diseases.At the field scale, these systems are used by growers to make economic decisions about disease treatments for control. Weather during inter-crop period is closely related to the survival of many plant pathogens, mostly through the severe cold of winter months and in some cases to that of pathogen vectors also. Requirements for Forecasting Plant Diseases 3. Forecast pathology demands a landscape‐scale perspective that acknowledges the movement ecology of interacting species and the influence of heterogeneous environments (Holdenrieder, Pautasso, Weisberg, & Lonsdale, 2004).
