Depends on what you are planting and the rates they sprayed at. It is just a guess without knowing, particularly what they sprayed and how much. However, you are looking at what, 6 months since they sprayed for a spring planting, give or take? Most herbicides they would be using shouldn't interfere with most things you plant. With that said, some crops are very sensitive to sulfonyl urea herbicide (like Oust) and may show some injury.

If you do the things you need to do when you need to do them then someday you can do the things you want to do when you want to do them.
