When I fertelize it's not uncommon for me to add in fungacide, superthrive,
wisk or sometimes pesticides.

Wondering if this is common or if the mixtures could do harm or counteract
each other.

I don't know for sure if it will harm them but, I remember reading and been
told that combining those things could sometimes harm the roots.
I have always been told to water with fertilizer, than at least one time
just water, than something else. Just always at least one time water with
nothing else, to clean te roots and medium, just in between the other
things.

Barry,

I'm going to leave it to others to be more specific, but as a general rule
it's not a good idea to mix chemicals without knowing just how the
ingredients will interact. There are some things that are fine to mix, as
long as you dilute with water before combining them. Others are not so
good. As I said, others will be more enlightening.

In addition to it being unwise to mix chemicals without knowing of potential
reaction, the preventive use of fungicides and insecticides can lead to the
growth of resistant strains. Your best bet is to avoid using them until you
see a problem. You can probably get by with a few home remedies (check the
URL below, under free info) unless you get into a mass invasion.

Superthrive is no problem unless you're using too much, in which case you'll
be likely to see deformed flowers.

What Ray said plus someone on another forum had suggested adding detergent
to the water - adds nitrogen and might kill a few bugs - so I tried it for
awhile but in the back of my mind thinking that it would break down the waxy
coating on the leaves making it easier for bugs and fuingi to invade. I
later read something similar and have stopped. Not sure if it hurt
anything... just my 2 cents.

On a large scale, cocktails are an industry standard. In the massive
operations, I have seen water systems with up to seven injector ports--lord
only knows what all they are mixing. Most of the commercial products are
made to be mixed together and come with mix testing instructions. If you
follow the mixing test and general use instructions, watch pH, and avoid
mixing copper based stuff into the cocktail you should not get into
problems. When in doubt try a test area and keep good records. I have no
ideas or comments about unlabeled stuff such as wisk.

With the way the weather has been here this spring, cocktails are the only
way we have been able to get everything we wanted to the plants as it has
been weeks between waterings. I also believe intelligent preventive use of
fungicides and insecticides is important. With the weather we have been
having, I know I am going to have fungi problems. Why wait to see the
problem? In July, I will start spraying for thrips - I know they are coming
and want to stay ahead of them and prevent visible damage.

Don't mix your chemicals. While some are designed to be compatible
(such as SUPERthrive + fertilizer), others work only in a narrow pH range.
Some fungicides and pesticides, for example, are carefully buffered so
that they'll work when you drop them into solution (i.e., add them to
water). All that goes down the drain when you throw in fertilizer (which
may be quite acidic) or another pesticide that is buffered to work at
another ph.
The other problem is that pesticides are sometimes created as a
particular chemical salt; the addition of other chemical salts (such as
those found in fertilizer, or another pesticide) may cause incompatibility
issues- it may cause one compound to precipitate, rendering it useless,
inactivating it, or possibly even causing it to be more toxic to humans or
plants.
