Find out what they sprayed if possible. It's hard to say how to help the land recover without knowing what was used, but mostly fungi seem to be the way to repair anything like that.
Remember you catch more flies with honey - better to wait until you calm down to talk to them, it's possible you can get them to stop spraying some of the areas if you ask the right person nicely. I've seen people get the mowers to stop mowing their roadsides where they had flowers or other stuff planted, they just had to agree to keep it weeded and not too high. If they are spraying for a particular pest (weed or bug) you might be able to stop the spraying by volunteering to hand weed or monitor the area for whatever thing they're worried about.
You can also make signs and put them up, "Organic farm - no spray zone", "No Spraying - Sensitive Wildlife Area" or something like that in case the workers are not informed. If you make it look official, in a bureaucracy it can often work for years before they figure out it wasn't someone in another department that put the sign up. LOL!
You can also plant a buffer zone on your land to protect the inner plants from spray - something hardy and inedible. Raspberries are hard, tho, they can be damaged by 2,4 D sprayed even half a mile away, as can blackberries and grapes.
