The two-body open charm decays Z+(4430)\ensuremath→D+D*0, D*+D0, D*+D*0 occur through the rescattering mechanism and their branching ratios are strongly suppressed if Z+(4430) is a D1D* molecular state. In contrast, Z+(4430) falls apart into these modes easily with large phase space and they become the main decay modes if Z+(4430) is a tetraquark state. Experimental search of these two-body open charm modes and the hidden charm mode \ensuremathχcJ\ensuremathρ will help distinguish different theoretical schemes.
