Somewhere on this site I saw a comment on using Roundup Ready sunflowers. Anyone know where they can be obtained... in the US?

Mycogen sells a clearfield sunflower.

You have to use their chems (not roundup), and they are $$$.

psandu, where would you get them? I see where Beyond is the herbicide and Clearfield is the seed, but have no idea where I'd find them. Guess I'll check with a local ag distributor.

fiik. sorry to be so blunt. maybe try some seed dealers or other similar typs of places.
