I didn't realize that the Casoron would stay in the air, etc. of the greenhouse. Needless to say, I haven't had luck growing anything this year. Is there a way to get rid of the effects of the Casoron?
Casoron 4G Herbicide does not get into the air and effect plants or soil that way. It can prevent things growing in treated soil as it is pre-emergent though. Since it can stay in the soil for at least 1 year, you would need to wait at least one year after application to replant or remove the treated soil and replace with new.
