Doesn't most growth of Orchard Grass happen in cool weather? If so it will be on the wane by the time Crabgrass grows enough to bale. Using herbicide first year will set newly planted grass back so I would overseed and wait a year or two before spraying Crabgrass then use pre-emerge. With Orchard Grass having a head start in Spring when Crabgrass germinates it might be shaded out to some degree. If Crabgrass isn't shaded out,you will have to apply herbicide every year until no seed remain in soil.
