No time in the summer. The biggest problem to my patch this year is. I'm spending so much time at work.
Do I need 8 sprayers or can I mix insecticide fungicides and federalize all in one sprayer and spray all at once.

Tom has me putting them all in together Darren. The only one he said to spray all alone is the Cal Mag Max.

I thought I was going to need 8 sprayers too,,,,,,,,,, so I took 6 back to Home Depot............. :)

most packaging also will tell you what is compatable and what is not.

Definitely read, then reread the label. If in doubt still, test a small spot before doing the whole patch.

copper is not compatable with many products as mentioned above.mixed incorrectly with other sprays will burn all the leaves.

Mix them in a jar prior to test..You mix Calcium Nitrate and something that I can remember at the moment you get a jello like substance

Darren- this is what I did to break my siphon on the sprinklers. Like you I think, I need to reduce the pressure in the line with a bypass valve and pipe returning some of the solution back to its tank. For example, my 50gal fertilizer tank runs to the pump, then the majority of the outgoing solution is sent out to the patch while a small portion gets returned to the tank. What I found out by accident is that when my pump turns off the siphon is killed by air getting sucked into the solution return line.

My pressure reducing ball valve is left 25% open at all times and the pipe that re-introduces the solution to my fertilizer tank ends about 6" above the tank. So when the pump is pumping I get water coming out of my return pipe, then it falls back in to the tank. This pressure reducing return pipe is the highest point in the system and when air gets introduced at the highest point it kills a siphon. When the pump shuts off solution stops coming out the return pipe and the siphon gets killed by the air being now sucked into the return pipe.

You still will have a drip out of your lowest sprinkler until all the solution is out of the lines. The only way to get around this is to buy the those pressure activated shut off valves and put one at every sprinkler. I think they are about $2 a piece at Drip Store.

I use no solenoid valves.

Hope this helps you out.
