We prove the vanishing of a certain class of equivariant quantum Littlewood-Richardson coefficients, which implies an equivariant quantum Pieri rule. As in the equivariant case, this implies an algorithm to compute the equivariant quantum Littlewood-Richardson coefficients.24 pages, LaTeXAlgebraic GeometryCombinatorics14N35 (primary); 14M15; 14N15; 57R91 (secondary)text
