Abstract: Downy mildew is one of the most serious grape diseases,the usual treatment method presently is the application of chemical fungicide,but excessive spray brings many severe problems. In order to solve the pollution of fungicide,accurate prediction and warning technology must be developed, accordingly the most appropriate occasion and amount of spray can be determined. In this paper, research progress, including epidemic system monitoring of disease, factor selection, structure and application of agrometeorological model in prediction of grape downy mildew is presented, and its problems and prospect were also discussed.
