Physan does not play nice with many other chemicals. I'd have to look it up
to see exactly what it is that it does, but it makes many kinds "gummy";
maybe a kind of polymerization? Especially those with Ca or Mg. If you are
taking cuttings of poinsettias or other milky-sap plants and don't like the
sticky sap, drop the cuttings in a bucket of Physan. They instantly stop
running and "clot" the cut end. Doesn't hurt rooting either as the plant
conserves its sap and gets a free disinfection at the same time. Try a few
drops of each together on a piece of waxed paper or plastic and see if
there's a visible reaction (whitish precipitate or overall opaque solution
develops). If so, don't mix them.

For the substance experts, or those who play them on TV:

I generally scrupulously avoid mixing chemicals, because I don't know
enough
about their properties to make educated decisions. I do know that when
chems are mixed they must be diluted first. Also, after talking to a
local
grower who has thousands of plants, I've added Orthene to my DynaGro when
needed, to avoid double work. No problems, and I am here to tell about it.

How about Orthene and Physan? It's *that time of year* here in S. FL. I'd
love to be able to do them together.

Any thoughts? (Silly question - I know you'll have some!)
