The present disclosure relates to, inter alia, a weed control method. In one example, a method comprises applying to the locus a weed controlling amount of a pesticide composition comprising a FatA acyl-ACP thioesterase-inhibiting herbicide, wherein the crop plants are modified such that they comprise a FatA acyl-ACP thioesterase which provides the crop plant with tolerance against the FatA acyl-ACP thioesterase-inhibiting herbicide. Recombinant polynucleotides and suitable for use in the methods, and edited FatA acyl-ACP thioesterases are also disclosed.
