Maintaining weeds in brassica plot

[DeerHunter3]

Looking for some help on maintaining our brassica food plot...we just broadcasted our purple tops, radish, and forage rape on Saturday. My question being what should I spray the weeds with and when?

We mowed and disc the plot.

Thank you

Clethodim and crop oil if grasses are bad. A good place to get it is keystone pest solutions. They will probably out-compete most broadleaf problems if you planted it right.
