摘要
以采用生长速率法测定了7种杀菌剂对万年青炭疽病病原菌的室内抑制作用,并进行田间药效试验,以进一步验证试验结果。结果表明:25%咪鲜胺、45%咪鲜胺、己唑醇、吡唑醚菌酯对病菌的抑制率均为100%,效果最好;苯醚甲环唑的防效次之;甲基托布津的抑制率虽然比嘧菌酯的高,但是甲基托布津不抑制分生孢子的产生;田间试验结果表明,25%咪鲜胺、45%咪鲜胺、己唑醇、吡唑醚菌酯防治万年青炭疽病效果均较好,可以交替使用,苯醚甲环唑的防效次之,嘧菌酯和甲基托布津的防效无显著差异,防效较差。
By means of the mycelium growth rate methods, the suppressive effect of seven fungicides on evergreen anthrax pathogens was tested. And at the same time, field experiments were conducted to verify the results of the experiment. Theresults showed that when using 25% prochloraz, 45 % prochloraz, hexaconazole, Pyrazole kresoxim-methyl, the inhibition rate to germs was 100 percents. The suppressive effect of difenoconazole follows closely. Though the inhibition ratio of thiophanate-methyl was better than azoxystrobin,Thiophanate-methyl not suppress the production of conidium. The field experiment results further proof that the suppressive effect of 25% prochloraz, 45% prochloraz, Hexaconazole, Pyrazole kresoxim-methyl on evergreen anthrax was better and can be used interchangeably. The suppressive effect of difenoconazole follows closely. The suppressive effect of thiophanate-methyl and azoxystrobin was bad and did not have any significant variation.
