几年来、通过调查研究,分析了用白粉寄生菌防治白粉病的可能性,并进行了初步防效试验,发现白粉寄生菌对白粉病寄生普遍,抑制效果显著,可用于生物防治。特别是农药残毒不断严重地污染环境、造成公害的今天,具有重要意义。白粉病对我省主要的粮食作物小麦(Triticum aestivum L.),重要的经济作物烟草(Nicotiana tabacum L.)、橡胶树[Hevea brasiliensis(HBK) Muell.-Arg.],名贵药材三七(Panax pseudo-ginseng Wall.)、枸杞(Lycium
In recent years, through the investigation and study, the possibility of using white powder parasitic fungi to control powdery mildew was analyzed and preliminary preventive tests were conducted. It was found that the white powder parasites were common to powdery mildew and had significant inhibitory effect and could be used for biological control. Especially pesticide residues continue to pollute the environment, causing pollution today, is of great significance. Powdery mildew was the main food crop in our province, Triticum aestivum L., Nicotiana tabacum L., Hevea brasiliensis (HBK) Muell.-Arg., Panax pseudo -ginseng Wall.), Lycium
