为了探明防治 Pestalotia logiseta Speg.诱致的茶灰斑病的有效杀菌剂及施用期,试验了三十一种杀菌剂,方法是:一、杀菌剂在接种分生胞子 PDA(马铃薯、葡萄糖、琼脂)培养基上形成的抑制圈。二、菌丝体在含有杀菌剂的 PDA 培养基上的生长。三、采摘以后的茶树施用杀菌剂。根据杀菌剂在接种分生孢子 PDA 培养基上形成抑制圈的方法,下列这些杀菌剂在含有1000 ppm 的纸碟周围可形成抑制圈:甲
In order to identify effective bactericides against Pestalotia logiseta Speg. And their application period, thirty-one bactericides were tested in the following ways: First, the fungicide was inoculated with mesenchymal PDA (potato, glucose, agar Inhibitory circles formed on the medium. Second, the growth of mycelium on PDA medium containing bactericide. Third, after picking tea fungicides. According to the fungicide inoculation conidia PDA medium inhibition circle method, the following germicides containing 1000 ppm in the paper around the disc can form inhibition ring: A
