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.

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.
