Clogged sprayer nozzle frustration

My patience was running thin this morning with the sprayer.

One nozzle on the end of the boom kept clogging for no apparent reason. Take it off, poke it out, rinse it out, blow it out. Put it back on and it was clogged again in 100'.

I even pulled the screen out of the nozzle base and cleaned it several times. There was a little bit of dried chemical in it the first time but perfectly clean every other time.

Finally had to give up and live without the nozzle. There will probably be some streaks in the field, but I'd still be out there if I kept fighting it.

There's nothing in the nozzle after clearing it. Why does it keep plugging?
 
The end of the line nozzle gets anything that the other nozzles don't. It is the end of the line.
When you can pump plain water thru all of it, then flush the system thoroughly. Has to be a deposit or build
up material somewhere.
 
When you are able, soak your sprayer
in household ammonia for a couple
days to clean out any chemical
build-up. Some of the chemicals we
use I have to put a little Dawn dish
soap in each tank when mixing to
keep it from quickly building up and
clogging all of the strainers. It
helps alot.
 
Yup. This.

Some sprayers have an el at the last nozzle; some have a pipe that the last nozzle drops off of and there is a bit of a dead end of the feed pipe past the last nozzle. This short dead end collects a lot of gunk, need to take the end off and flush that out to really clean up that design.

If no build up of old chemical or debris in the line, then you need a finer main screen. I was having the same type of problem with a tank of spray that had to set over night one time. Spent more time cleaning after cleaning all the filters lines and boom filters before filling. Was so pee od by the time I came home empty with it. I felt sick from the heat and stopping all the time. I cleaned out the booms and screens again after I got home washed out the pump filters and then no more trouble with it. I have 3 filters a main for the suction line to the tank and 2 more in the boom lines they are finer than the suction line screen. I wash my filters out each tank full much easier than fooling around in the field.
 
Question for those that reply. Are most clogs the result from powder mix chemicals, rather than liquid chemicals?
 
Purity of water matters more with modern chemicals than the days of 2-4D and Attrazine. A lot of stuff will bind with the water
then catch in the screens. When I went to municipal water many years ago all those problems went away.
 
Check if the inside of some of the hoses are breaking down. It may be time to replace the hoses.
