Starting from a three-wave interaction coefficient for a homogeneous Vlasov plasma we show that the parametric decay to half-harmonics has a zero growth rate if the pump wave wave number vanishes. Earlier proofs of this fact for electrostatic decay modes are then extended for a general case. As a specific example we study the decay of a fast magnetosonic wave to two slow waves.
