Physan 20 and Polycarbonate

[BrassavolaStars]

Hello All,

For a different theme of question not specifically about orchids, does anyone know if Physan 20 reacts with polycarbonate?

I was spraying the orchids in my greenhouse with physan 20 and it is almost impossible to avoid getting the walls wet.

Is this going to bother the walls? I know that Polycarbonate reacts and melts when it comes into contact with certain solvents like acetone.

Will Physan, or for that matter, anything like physan, cleary's, or other pesticides have those disastrous properties on polycarbonate?

My greenhouse in PA was PC-covered, and in 25 years, never saw an issue.
