  We have examined the dijet production at the LHC as a hint to discovery of
string Regge excitations of Standard Model particles. If the fundamental string
mass scale is in the TeV range, the influence of string effects on the $pp$
interaction can arise as new resonances in the dijet invariant mass
distribution. Near the first resonant pole we investigate the impact of the
subprocesses with quark-gluon and four-gluon separately. We show that the LHC
is able to probe the string mass scale $\sim$5 TeV with only 2 pb$^{-1}$ of
integrated luminosity at $E_{CM}=14$ TeV.
