and
(B4) sethoxydim, cycloxydim, and clethodim; wherein
the cotton crops are tolerant to the herbicides (A) and (B) contained in the combination, optionally in the presence of safeners, and wherein the combination of herbicides (A) and (B) provides a synergistic effect and gives a greater activity than the herbicide (A) and the herbicide (B) alone.
