Strong selection by
herbicides, especially repeated treatment with herbicides having
the same mode of action, has resulted in the wide spread evolution
of herbicide resistance in populations of agricultural weeds
(Jasieniuk et al., 2008; Powles and Yu, 2010; Heap, 2011). In China,
repeatedly applying tribenuron has resulted in serious resistance of
main weed Descurainia sophia (L.) Schur. to this herbicide (Cui et al.,
2008; Jiang et al., 2008). It urgently needs to develop new herbicides
as an alternative measure to control broadleaf weeds in
wheat.
