I will discuss the $\pi\eta^{(‘)}$ production in the double Regge model. The model explains the forward-backward asymmetry observed in this reaction by associating it with the exotic $P-$ wave, which in turn is related to the production of the putative $\pi_1$ hybrid meson. I will also discuss the Regge and Deck production of $\pi\pi$ resonances. The interference of the Deck and direct production explains the pion angular distribution for invariant masses below 2 GeV.
