1st off, call True Green & find out EXACTLY what they sprayed on the hops: Type of herbicide, type of fert, was there a spreader sticker used, any insecticides, etc...
Those services usually spray a mix of fert, broadleaf herbicde (contact and/or systemic), and some type of insecticide.
Also, find out if the hops were sprayed directly, or if it's just overspray or drift; it can make a difference. Once you know this info, you'll be in a better position to try to save your rhizomes.
Now, True Green is responsible for replacing your rhizomes. They sprayed 'em, they should replace them. Same goes for anything else they damaged/killed/contaminated. Even if your hops survive, bill True Green for the cost of replacement. I'd also ask them for a refund. I'm not sure how they do things in your state, but some states require pesticide applicators to pass required tests and/or pass required continuing education classes to maintain their certification(s). Keep an eye on any other plants they may have sprayed, and keep a close eye on your lawn.
If they were stupid enough/careless enough to spray your hops, they may have striped your lawn too; look for dark green stripes to appear in your lawn. Striping comes from a sloppy, overlapping spray pattern & wherever the spray patterns overlap, twice the amount of mix was applied, hence the striping. Striping can (depending on the mix) burn grass in the overlapped areas.
Good luck to you. Regards, GF.
