On the basis of a simple model we analyse the influence of disorder on critical temperature T_{c} in p-wave superconductors. The disorder is treated by means of the coherent potential approximation and we focus our attention on the effect of a van Hove singularity near Fermi energy E_{F}. For the appropriate values of its parameters our model reproduces the experimentally found behaviour of Sr_{2} RuO_{4}.
