| 摘 要： | 打瓜白粉病是打瓜上最严重病害之一,给生产带来了严重影响。探讨白粉病的发生特点、防治具有很重要的意义。2008年通过调查得出,福海县打瓜白粉病的发病初期为7月初,气候条件适宜时,7月底8月初病害达到高峰值,发病率可达100%,发生面积广,危害程度重。2007年通过药剂筛选试验,筛选出防治效果较好的药剂为福星、敌力康,防治效果达77.02%、73.90%。因此,控制好打瓜白粉病的严重危害,必须抓住防治关键时期,于病害发生前期,即6月底7月初进行喷药预防,以后每隔7～10 d喷药防治一次,喷3～6次,可以取得好的防治效果。 |

| Abstract: | Watermelon powdery mildew is one of the most serious diseases,which brings about serious impact on production,therefore,to explore the characteristics of the occurrence of powdery mildew,prevent and control its diseases is very important.The results from the investigation carried out in 2008 showed that watermelon powdery mildew happened at the beginning of July in Fuhai County,when climatic conditions was suitable for occurrence of the diseases,it reached high peak at the end of July or early August,percent infection was up to 100%,in wide area with serious damage.The chemical screening test was conducted in 2007.Among them fuxing and Dilikang had good effect,the effect reached 77.02%,73.90%.Therefore watermelon powdery mildew were brought under control.
