| 摘 要： | 为明确高粱田主要杂草对HPPD抑制剂类除草剂喹草酮的抗性,采用整株生物测定法测定马唐Digitaria sanguinalis、稗Echinochloa crusgalli、狗尾草Setaria viridis、野稷Panicum miliaceum、反枝苋Amaranthus retroflexus和藜Chenbopodium alum六种主要杂草的敏感种群对喹草酮的敏感基线,同时测定全国不同生态区高粱田中这6种杂草对喹草酮的抗性水平。结果显示,喹草酮对野稷、稗、反枝苋和藜的防除效果较好,GR50介于12.76～32.72 g (a.i.)/hm2之间,GR90介于68.04～193.54 g (a.i.)/hm2之间,对马唐的防除效果略低,GR50介于44.23～56.19 g (a.i.)/hm2之间,GR90介于472.26～849.24g(a.i.)/hm2之间。采自全国不同生态区高粱田的马唐、稗、狗尾...

| Abstract: | In order to assess the risk of resistance to quinotrione,a new type of HPPD herbicide,the sensitivity baselines of six weed sensitive populations,Digitaria sanguinalis,Echinochloa crusgalli,Setaria viridis,Panicum miliaceum,Amaranthus retroflexus and Chenopodium album,to quintrione were determined in greenhouse,and the resistance levels of weed populations in sorghum field were also determined.The sensitive baseline test showed that E.crusgalli, P.miliaceum,A.retroflexus and C.album,were more sensitive to quinotrione with GR50 from 12.76 to 32.72 g(a.i.)/hm2 and GR90 from 68.04 to 193.54 g(a.i.)/hm2,than D.sanguinalis with GR50 from 44.23 to 56.19 g(a.i.)/hm2 and GR90 from 472.26to 849.24 g(a.i.)/hm2.The resistance level test showed that all populations of six weeds collected from sorghum fields in China were not resistant to quinotrione,and the relative resistance index was below 2.00.The populations which were resistant to nicosulfuron were still sensitive to quinotrione and mesotrione.The results showed that quinotrione,as a low-risk herbicide,used to control weeds in sorghum fields,the risk of weeds develop resistance to it would be very slow. |
