Does Burpee or Ferry Mason Chemically Treat Seeds?

The only common comsumer packets of seeds I've seen that are treated with fungicide are sweet corn. Fungicide treated seeds in the US have to be dyed "unnatural colors" -- bright pink is pretty common. Beyond that, you can find seeds of peas and beans that have been treated with the proper strain of Rhizobium bacteria to nodulate -- but that's usually a dry, dusty powder of bacteria in a clay or talc carrier.

Why not talk to Burpee or Ferry Morse to see if the seeds you bought are treated?
