Herbicidal compositions containing the DPE
together with one or more of dicamba, mecoprop and ioxynil show a surprising herbicidal effect, especially on weeds commonly found amongst cereal crops.
The ioxynil can be partly or completely replaced by bromoxynil and the mecocrop can be partly or completely replaced by dichloroprop and/or MCPA. Useful commercial ratios of DPE: ioxynil (and/or bromoxynil) are 20 to 30:200 to 400, of DPE: mecoprop (and/or dichloroprop and/or MCPA) are 20 to 60:800 to 1600 and of DPE: dicamba are 30 to 60:45to 75. Methods of controlling the growth of weeds wherein the compositions are applied to growing weeds or to a growth medium prior to weed emergence are also disclosed.
