When using Image Kills Nutsedge Concentrate or most post emergent herbicides on the market, you would need to wait until the new sod/grass has become established and been mowed at least 2-3 times before safely applying as a broadcast application to the new zoysia sod. Until it has become established you can use careful spot treatments to eliminate any existing weeds.
