近年来,随着保护地生产的发展,黄瓜灰霉病日趋加重,给蔬菜生产造成很大威胁。据1986年春我市太和区调查,全区1,000多亩保护地黄瓜发病面积达400多亩,严重地块黄瓜发病率达65％,减产一半左右。由于黄瓜灰霉病发展的较快,又没有较好的药剂防治,因此给黄爪的产量及菜农的经济收入带来了很大影响。 In recent years, with the development of protected area production, cucumber gray mold is aggravating day by day, causing great threat to vegetable production. According to a survey conducted in Taihe District in the spring of 1986, the disease area of ​​over 1,000 mu of protected cucumber in the whole area reached 400 mu and the incidence of serious cucumber in the block reached 65% with a reduction of about half. Due to the rapid development of Botrytis cinerea cucumbers and the lack of better agent control, the yield of yellow claws and the economic income of vegetable growers have been greatly affected.
