This paper characterizes the boundedness of the differences of the products of extended Cesaro operators and composition operators from F(p, q, s) space to mu-Bloch type space on the unit ball of C-n. At the same time, some asymptotically equivalent expressions of the essential norms of difference of products of generalized Cesaro operators and composition operators are presented. As some corollaries, the compactness of the difference operators are also characterized.
