We have studied some properties of the secondary particles in p-p interactions which are obtained on the basis of the quark gluon string model. This model is tuned with FNAL and ISR data at 20 GeV. The rise of the predicted inelastic cross section agrees with accelerator data up to 1.9 Tev (SCM). The asymptotic behaviour of secondary particle spectra with scaling in the fragmentation region leads to a rather slow rise of multiplicity. An improved parametrization will help the study of hadron interactions at the highest energies and explain some exotic events which are observed in cosmic ray experiments.
