Study on the Technology to Prevent and Control Grape Disease Downy Mildew on Vitis Amurensis Rupr in the Northeast

1997～2000年进行山葡萄霜霉病的防治试验，结果表明新型杀菌剂72％杜邦克露，58％雷多米尔锰锌，69％安克锰锌等，防效达66.42％～77.73％。建议：在今后生产中，以早期预防为主，喷洒波尔多液和新型杀菌剂。

：During 1997～2000，the experiment on prevention and control grape disease Downy Mildew on VITIS Amurensis Rupr was conducted. The results indicated: The effectiveness of some new types of fungicide such as 72％ DUPONT CURZATER-M8，58% RIDOMILR-Mz，69％ ACROBAT*-Mz etc reached 66.42％～77.73％. The paper gives a suggestion: To prevent and control disease in grape production，it would be best to pay attention to early stage of grape growing，mainly to spray Bordeaux Mixture and new types of fungicide.
