| 摘 要： | 在测定使它隆、农达、农思它、盖草能等除草剂对莲子草假隔链格孢(Nimbyaalternantherae)菌丝生长和孢子萌发抑制作用的基础上,研究了使它隆和农达与莲子草假隔链格孢混用防除空心莲子草的可能性实验结果表明:在1000倍的浓度下几种除草剂对该菌菌丝生长的相对抑制率依次为农思它(955%)>盖草能(80%)>使它隆(694%)>农达(445%);对孢子萌发则只有农思它稍有抑制作用(174%),其它3种均无抑制作用;2000倍的使它隆和农达分别与40g/L菌丝(湿重)的莲子草假隔链格孢菌丝悬浮液等量混合比单纯使用除草剂或菌丝悬浮液的除草效果好

| Abstract: | It was showed that Fluroxypyr, Glyphosage, Haloxyfop-ethoxyethyl and Oxadiazon could inhibit the mycelium growth, but not the conidium germination, of Nimbya alternantherae in vitro under 1 000 times of dilution. Inhibition percentage of tested herbicides on mycelium growth was respectively 95.5%(Oxadiazon), 80% (Haloxyfop-ethxyethyl), 69.4%(Fluroxypyr) and 44.5%(Glyphosage). Fluroxypyr or Glyphosage of diluting 2 000 times mixed equally with hyphae segment suspension of 40 g/L of Nimbya alternantherae (wet weight) gave better control effect on alligator weed in vivo than Fluroxypyr or Glyphosage or hyphae segment suspension did alone. |
