The two-body open charm decays Z{sup +}(4430){yields}D{sup +}D*{sup 0}, D*{sup +}D{sup 0}, D*{sup +}D*{sup 0} occur through the rescattering mechanism and their branching ratios are strongly suppressed if Z{sup +}(4430) is a D{sub 1}D* molecular state. In contrast, Z{sup +}(4430) falls apart into these modes easily with large phase space and they become the main decay modes if Z{sup +}(4430) is a tetraquark state. Experimental search of these two-body open charm modes and the hidden charm mode {chi}{sub cJ}{rho} will help distinguish different theoretical schemes.
