瓜类花叶病毒病是影响广州市郊区瓜类生产的主要因素之一。黄瓜花叶病毒引起的瓜类花叶病有春植冬瓜花叶病和秋植节瓜、黄瓜花叶病。1985年新(?)区春植冬瓜共8400亩,其中发病的有650亩,一般发病株率15—25％,严重的50％以上,甚至失收。而秋植节瓜和黄瓜花叶病则广泛发生,为害严重。我们于1986年春开始,引进黄瓜花叶病毒生防制剂——卫星病毒(S_(-52))防治春植冬瓜化叶病,初步取得成效;7月间又用它防治秋植节瓜和黄瓜花叶病,也取得较好的防效。在北方,S_(-52)也用于防治番茄和辣椒花叶病取得良好的效果,但未用于防治瓜类花叶病,因此,我们便采用多种方法进行对比试验,从中找到一种比较好的方法。
Melon mosaic virus disease is one of the main factors that affect melon production in the suburbs of Guangzhou. Cucumber mosaic virus melon mosaic disease have spring melon mosaic disease and autumn melon, cucumber mosaic disease. In 1985, a total of 8,400 mu of spring melon was planted in the spring (?) Area, of which 650 mu was the most common disease, with a rate of 15-25% of the total incidence and a serious 50% or more of the disease. Autumn melon and cucumber mosaic disease is widespread, serious damage. We started the spring of 1986 with the introduction of cucumber mosaic virus biocontrol agent - satellite virus (S _ (- 52)) to prevent and control winter melon leaves, and achieved initial success. In autumn, we used it to control autumn melon and cucumber Mosaic disease, but also achieved better control effect. In the north, S_ (- 52) is also used to control tomato and pepper mosaic disease to obtain good effect, but not for the control of melon mosaic disease, therefore, we will use a variety of methods to conduct comparative tests to find a The better way.
