Mixing: there is a test that works "most of the time." No guarantees, and
YMMV. But if you mix up a very small test quantity of the two chemicals,
let the mix rest overnight, and it's still mixed rather than separated, and
not turned to mud, or turned some outrageous color by morning, it has a good
chance of being OK to spray. Next step would be to use the test batch on a
couple of test plants ... Kenni

Hi everyone... Does anyone know can I tank mix Phyton 27 and Physan and
spray them together in general on orchids? And does anyone know of a
website that might list this sort of data?

Thanks!
Jerry
