The present invention relates to a method for controlling parasitic weeds, comprising applying to the host plant, the weeds and/or their habitat herbicidal mixtures or compositions comprising one, two or three acetolactate synthase (ALS) inhibitor(s) and one, two or three plant growth regulator(s) (PGR) which act as ethylene modulators. The present invention also relates to a method for improving the yield of the crop plant comprising applying to the host plant, and/or their habitat mixtures comprising components as defined herein. The present invention also relates to herbicidal mixtures comprising one, two or three acetolactate synthase (ALS) inhibitor(s) selected from imazamox or tribenuron-methyl and one, two or three plant growth regulator(s) (PGR) selected from prohexadione, prohexadione-calcium, trinexapac or trinexapac-ethyl, compositions comprising said mixtures and their use for the control of parasitic weeds.
