月季花白粉病(Oidium rosae-indicae Saw)发生普遍,受害植株布满白粉,叶片皱缩卷曲,生长缓慢,轻则影响开花,失去观赏价值;重则停止生长,甚至枯死。目前,防治月季花白粉病都使用多菌灵、托布津、粉锈灵等化学农药,长期使用,使白粉病菌产生抗性,也会污染环境。1983年,我们应用中国农科院研制的农抗120,防治月季花白粉病的试验,1985年示范推广,取得了显著的效果。
Occurred in the rose powdery mildew (Oidium rosae-indicae Saw) occurs generally, the victim plants covered with white flour, leaf crimps curly, slow growth, ranging from the impact of flowering, loss of ornamental value; rest stop growing, or even dead. At present, the prevention and treatment of rose powdery mildew are used carbendazim, thiophanate, pink rust and other chemical pesticides, long-term use, powdery mildew resistance, but also pollute the environment. In 1983, we applied the test of Nongkang 120 developed by Chinese Academy of Agricultural Sciences to prevent and control rose powdery mildew in demonstration in 1985 and achieved remarkable results.
