We investigate the possibility of probing R-parity violating interactions in forward-backward asymmetries, and conclude that the Tevatron collider is the best place to measure new interactions involving the first generation of quarks. With additional down type squark ~dk contributions, the charge asymmetry in e+e- events around Z-pole mass region at the Tevatron will be sensitive to R-parity violating couplings λ’11k, which was inaccessible to the LEP Qfb had inclusive measurement. Assuming no apparent deviation from SM prediction is observed, λ’11k〈 0.19 at 95%C.L. with squark mass Mdk=100 GeV can be derived.
