Sprayer What PSI for a sprayer?

   / What PSI for a sprayer? #11  
Tee jets are great nozzles and the ones that I use as well, but there are many different nozzles out there. You want to be able to calculate the pounds of materials that you are applying at any time. This is done by knowing the % solution that you are using, your nozzle flow rate, and you only need to use the flow not the number of nozzles that you have and pressure at the nozzle to figure out the land speed needed to do a correct application.

It is correct that you do not want to atomize your spray but have it in very small but defined droplets for spraying.

There are many things that can contribute to drift such as temperature, type of spray, wind, travel speed etc.

For example the 2,4-d ester will atomize between 80-90 degree f and will travel and settle where you did not intend on the application being placed, bad. The amine is much more stable and will not do this to the degree as the ester, good. The ester is a much more effective chemical, bad in that I don't like using it.

Do you use a kicker or spreader/sticker in your mix? that will affect the result of your spraying.

The list goes on. There are many resources on this topic, find one and do some research.

Just my 0.02.

PS I have a very good friend that is a vintner and bee keeper, both his vines and bees got wiped out this year by a professional sprayer this year. He will get insurance money for this crop, but it will take him years to recover. Remember spray does not know boundaries.

What name brand sprayer do you have? I have looked at the TSC sprayers with the 10 or 12 foot booms but I diffently like the 20 foot if the price won't kill me
Also is the pump PTO driven or just a 12 volt electric pump?

I built my own last year with a 10 foot boom but the tank is only 15 gallons, would like to move up a notch or two

I have a four nozzle yard sprayer on a 6' boom (covers about 7') and run at about 15 psi. I use a pressure gauge and watch it that way. I prefer to not get a lot of fine mist in the air, and keep the droplets as large as possible. Works great for me, and I use the Shur flo 12v pump. Built my own rig.
