We demonstrate that if the exponent γ that measures nonsmoothness of the velocity field is small then the isotropic zero modes of the scalar's triple correlation function have the scaling exponents proportional to √γ. Therefore, zero modes are subleading with respect to the forced solution that has normal scaling with the exponent γ.
