As no product is available at the moment in Hungary for efficient bedstraw control in winter rape by in-crop application in spring, the herbicide Starane 250 EC (fluroxypyr-1-methylester) exhibiting excellent bedstraw control was involved in studies.The product was applied alone or in mixture with Lontrel 300 (3.6-dichloropicolinic acid) and Perenal (haloxyfop-r-methylester).During the trial susceptibility of winter rape was studied using different rates and times of application.Starane 250 EC was used at rates of 0.21;0.3;0.45;0.6 l/ha applied at rosette stage and stem elongation-beginning of flowering.Phytotoxicity on the crop was quantified.The trial was assessed one,three and four weeks after treatment.It was concluded that Starane 250 EC is recommended to apply only at 0.3 l/ha at rosette stage, later treatments had phytotoxic effect on the crop.
