摘要
以孢子的萌发率为指标,在涂有一层杀菌剂药膜的琼脂表面接种金龟子绿僵菌Metarhiziumanisopliae的Ma83菌株孢子悬浮液,研究6种常用化学杀菌剂使用后不同时间对绿僵菌Ma83萌发的影响。试验结果表明,除保护剂波尔多液外,其它几种杀菌剂对孢子均有较强的杀伤作用,其中瑞毒霉、百菌清和甲基托布津对孢子的杀伤率100%,24 h未见有孢子萌发。随着时间的延长,药剂对孢子萌发的抑制呈下降趋势,但下降速度缓慢。
The effect of 6 fungicides on germination of conidia of the strain Ma83, Metarhizium anisopliae,in different time was studied. The results showed that except Bordeaux mixture, the fungicides inhibited conidia of Ma83 significantly, with 100 % inhibition by metalaxyl, chlorothalonil and thiophanate methyl within 24 h. The germination rate increased slowly several days after fungicide treatments.
