A possibility of additional energy loss of scalar gravitational waves radiation is considered using a totally nonmetric gravidynamics model. Scalar gravitational luminosity in gravidynamics is considered to be of the same order of magnitude as the system energy loss for the radiation of the usual tensor gravitational waves of general relativity. It is suggested that, for a binary system with nonzero eccentricity, it is necessary to take into account the effect of scalar radiation on the secular radiation of the companion's orbit parameters. The contribution of scalar radiation into a total gravitational luminosity of the system with a radio pulsar PSR 1913 + 16 can be about 2.2 percent of the radiation power of the tensor gravitational waves. It is concluded that scalar radiation can significantly affect fall rate measurements of the binary system orbital period (Pb), and the corresponding contribution into Pb can be delta Pb of about -0.053 x 10 exp -12s/s.
