On the electron-positron storage ring VEPP-2M using the Cryogenic Magnetic Detector, the cross section of the e+e- -> π+π-⁢π0 process was measured in the energy range 2x420-2x510 MeV. The energy dependence of the cross section is consistent with the predictions of the vector dominance model taking into account the interference of omega and phi mesons. The optimal value of the omega-phi interference phase is 136+-36+-10 degree.
