First, I would phone (or better yet, visit in person) the agency doing the spraying to find out what they are using.
IMO, I wouldn't want any of it near my plants, but some are less evil than others.
Knowing what you are dealing with should be the first step.
That way, you can research specifically on known issues.
Until you can determine what they are spraying, assume the worse, and act accordingly.
Cover/protect whatever plants you can, rinse off afterwards, etc.
As far as the bee hive goes, try to find a spot well off of the highway, possibly behind the house.
You may not be able to keep the spray off of all of their food sources, but at least keep it off their home.
While you or I would probably have pages of legal issues/permits to use such poisons, government agencies I have had experience with usually seem to think that they are exempt from the restrictions.
Good luck.
