摘要
室内12种杀菌剂筛选结果,多菌灵对杉木缩顶病两种病原菌(Pestalotiopsisguepinii和Fusarium oxysporum)在低浓度下均有很好的抑制菌丝生长能力。在发病高峰前燃放多菌灵烟剂并结合4月初的施硼、钾肥及抚育等林间综合防治方法可使幼林的杉木缩顶病的防治效果达64％以上。这种方法能为生产单位接受。
Bavistin was a good systemic fungicide which was selected from 12 fungicides in laboratory. It was effective to restrain mycelia growth of Pestalotiopsis guepinii (Desm) Stey and Fusarium oxysporum Schlecht in low concentration. Before rapid-developing period of Chinese fir mop-top disease combining the application of bavistin aerosol with the fertilization of potassium and boron in early April was great value for controlling the disease, with efficiency over 64 per cent. This method could be accepted by foresters.
