根据近年来小麦白粉病宏观管理的研究和宏观植物病理学原理,结合多年从事全国小麦主要病虫害预测预报及其宏观管理的实践经验,提出实施小麦白粉病宏观管理,应以病害监测预报、流行区划、防治药剂筛选、损失测定与防治指标等基础研究为基础,以选育和推广种植抗病品种和保健栽培为主线,以控制菌源基地为重点,以科学用药为最后防线,从而达到提高作物抗病能力,减少病原基数,推迟发病始期,降低流行速率,控制大面积病害流行的目标。
According to the macroscopic management of wheat powdery mildew in recent years and macroscopic plant pathology, combined with years of practical experience in predicting and forecasting major wheat pests in the whole country and putting forward the macro-management of wheat powdery mildew, we should take the monitoring and prediction of diseases, epidemic division , Prevention and treatment of drug screening, loss determination and control indicators and other basic research based on the selection and promotion of planting resistant varieties and health cultivation as the main line to control the source of bacteria as the focus of scientific medication as the final line of defense, so as to improve the crop Disease resistance, reducing the number of pathogens, postponing the onset of disease, reducing the prevalence rate and controlling the spread of large-scale diseases.
