Subclass of Horndeski gravity without Vainstein screening mechanism is tested in strong field regime of binary pulsars. Two specific cases of the Horndeski gravity are considered: the hybrid metric-Palatini f(R)-gravity and massive Brans-Dicke theory. The observational data of PSR J1738+0333, PSR J0737-3039, PSR J1012+5307 is used for obtaining constraints.
