| Abstract: | Shepherd's purse seeds were collected from winter wheat fields and road sides in Hebei Province,China.Their sensitivities to tribenuron-methyl were evaluated in a whole plant dose response assay in the greenhouse.Results revealed that HB1,HB-2,HB-3,HB-4,HB-6,HB-7,HB- 17,HB- 18,HB- 19,HB-20,HB-21,and HB-22 populations were susceptible to tribenuronmethyl characterised by very low GR50 values of about 0.10 g a.i.ha-1.On the other hand,populations HB-15 and HB-16 had moderate resistance to tribenuron-methyl with resistance indices (RI) ranging from 10-100 folds,whilst populations HB-5,HB-8,HB-9,HB-10,HB-11,HB-12,HB-13,and HB-14 expressed high level of resistance to tribenuron-methyl with resistance indices over 100.The proportion of moderate resistance level was about 9.09％,and that of high resistance was about 36.36％. |
