Abstract
We apply Bogolubov approach to QCD to demonstrate a spontaneous generation of three-gluon gauge invariant effective interaction which contributes significantly at the infrared region. The contribution of this interaction to leads to description of its behaviour in correspondence to phenomenology and lattice calculations without introduction of any additional parameter.
