Physan and Misting System

[wetfeet101b]

I would just like to touch on the California-EPA restrictions on Physan 20.
I have contacted the manufacturer since this is a concern for me as well (I live in California and I sometimes have the need to use Physan 20 on my orchids).
And in fact, I have never seen the California restrictions on my 8oz bottle - since there was none printed.
But after reading this thread, I looked at the different Physan 20 bottles at Home Depot and indeed the 1gal jug had the restriction printed.

Here is a response directly from Maril Products regarding the "Not approved for use on plants in California":
"Thank you for your message. The gallon label that you refer to is an outdated label. Physan 20 is approved for use on orchids in California."

They also sent an attachment for the updated application concentrations, and those resemble the new 8oz labels.

I guess at one time they had the California restrictions printed on their labels and once Cal-EPA approved Physan 20 for that application they updated their labels. But since the 1-gallon jugs take a while to be used up, the inventory of old labeled jugs are still on the market.

Of course, that does not mean that the product is any "safer" than before, and obvious common-sense safety practices should always be observed.

Happy Growing.
