By assuming the Z(4430) as a tetraquark state, we study the production of neutral Z(0)(4430) by antiproton-proton annihilation through the s channel with the approach of an effective Lagrangian in terms of hadrons. Meanwhile, the background from the (p) over barp -> Psi'pi(0) process through the t and u channels by exchanging a proton is also considered. It is found that there exists an obvious peak for the production of signal near the Z(4430) threshold. Also discussed is the feasibility of searching for the neutral Z(0)(4430) at the PANDA detector, which will be important in promoting a better understanding of the exotic tetraquark candidate, both in theory and through experimentation.
