黄瓜霜霉病是我区威胁黄瓜生产的毁灭性病害。无论在温室、塑料大棚或露地蔓延都十分迅速,一旦病害流行,许多措施都难于奏效。在药剂防治中,过去生产上多用退菌特、代森锌等农药,由于它们都是保护剂,防效只有50%左右。为此我所于1979～1980年用新杀菌

Cucumber downy mildew is a devastating disease in our region that threatens cucumber production. Both in greenhouses, plastic sheds or in the open have been very rapid and many have struggled to get out of the way once the disease has hit the ground. In the prevention and treatment of pesticides, in the past the production of multi-use antidote, dexmedetom and other pesticides, because they are protective agent, control effect is only about 50%. For this purpose, I used the new germicidal method from 1979 to 1980
