Default Mixing Chemicals?

Gary makes a real good point about form. I do not like using chemicals
dissolved in petroleum distillate and a double or triple dose of the stuff
could really get you into trouble. Manufactures are making fewer power
forms of the sprays to reduce mixing risks. Many of the newer forms are
"liquid" but not petroleum based. I do not think Cleary's 3336F is petroleum
based, but I have seen Orthene in a petroleum base.

I'm not sure about Cleary's since I haven't used it. I would think that it
would be fine is you've used them both before individually. Another
consideration in mixing is "is it in dry or liquid form?" Most liquid form
chemicals are dissolved in an organic solvent like petroleum distillate.
One dose is probably ok. But when you add one dose of this and one dose of
that you're adding up to a lot of doses of organic solvent. A plant may
tolerate 1 dose just fine but not any more. This goes also for those guys
that think 1 dose is good so 3 is probably better. So try for dry
chemicals if at all possible and use as little as does the trick. As for
your initial question, mix a small amount of each together and check for a
precipitate in 1/2 an hour. Cleary's instructions state

"Tank Mixing Instructions: 3336 F is compatible with most commonly used
pesticides.
If tank mixing with other materials,add products in the following
order:water soluble bags,
wettable powders,dry flowables,liquid flowables,emulsifiable
concentrates,and soluble
materials such as fertilizers.No claim of compatibility with other
products is implied.Do
not tank mix with copper-containing materials or with highly alkaline
pesticides,
such as Bordeaux mixture or lime sulfur. Consult the intended tank mix
partner
product label for appropriate application rates and use
instructions.Follow the label directions
for the most restrictive of label precautions and limitations.This product
cannot
be mixed with any product containing a label prohibition against such
mixing.Read and
observe the most restrictive precautionary statements and other
information appearing
on product labels used in mixtures. 3336 F may be applied in conjunction
with chemically
neutral liquid fertilizers.Application in conjunction with highly alkaline
fertilizers,
such as aqueous ammonia,may cause a degradation of the pesticide,resulting
in reduced
performance and should be avoided.

Since Orthene is not in these categories spray away.

Good info, Gary. Know anything about mixing Cleary's 3336 with Orthene? I
am more concerned about that combination than using the stuff with
fertilizer. I need to do a spray tomorrow, and would love to hit them
with both insecticide and Cleary's at the same time.

I love this group. So many good minds.

I know Physan, Phyton 27, Subdue, and Orthene all play nice together
along with Distance and Enstar, Decathlon, Marathon II, and all the
expensive miticides (Floramite, Pylon, Akari...). Some of these may not
work well with fertilizers. I know Physan and fertilizer cause a fine
precipitate which is probably taking some of the nutrients out of
solution. Some of the others are hard to tell since they turn white in
water solutions. The precipitate is what you want to look for in a
reaction. I don't think any of them will fizz or go kaboom. The
precipitate may be so fine it just looks like a cloudy solution. But it
will begin to clump or form sandy-like grains on the bottom after sitting
for awhile. Hope this helps some.

All:

I know I can mix certain fungicides with each other. My question is,
which of the following, if any, would also be compatible with Orthene?
Any? None?

Cleary's 3336; Subdue; Phyton; Physan.
