The 2 backpack sprayers I use are mostly for weeds & lesser for insecticide
for flowerbeds. IE, one sprayer for glyphosate, the other for not
glyphosate. My insecticide sprayer is for 2 gallons at a time; it's a Solo.
The larger sprayer is for the weeds, and I do about 3 fills 3 gallons per
session. This sprayer (the one which leaks, and I can't recall the
manufacturer) has not only the helpful hip-strap, but also the handle can be
changed fairly easily from one side to the other. If you've had a shoulder
or elbow injury, this feature is very nice!!

I don't spray apple trees, sorry. Mine's just a hobby & attempt to share
what I grow. If I did spray, I'd definitely shop for or try to build one of
the wheeled sprayers. And the spray would need to reach into semi-standard
trees! I think it might be easier to start over with more- dwarfing
rootstocks.

I wish I could offer makes & models, but haven't kept up on that.

I been researching backpack sprayers, but haven't used one yet. I read
somewhere that the models Solo currently sells have the capability to attach
the pump handle on the left or right side. They sell piston pump models that
go up to 90 psi or diaphragm pumps that go to 60 psi. The piston pumps won't
handle wettable powders/water dispensable granules (many pesticides are
WP/WDG) because the abrasiveness of the granules is hard on the seals. The
diaphragm pumps are supposed to work well with WP/WDG but they don't put out
as much pressure. Solo's are fairly cheap sprayers but a disadvantage I've
heard is that you can't hardly get the pumps apart to maintain/replace any
parts.

I think a long wand will help with a higher reach. Solo sells a 5ft. wand.
I've also learned SP systems sells even longer wands. They sell a 66" brass
wand and a 78" fiberglass wand. Although their sprayers are more costly,
their SP0 backpack sprayer is a diaphragm that has a working pressure up to
80psi and a max pressure of 150psi. Their SP0 models also have a built in
agitator that "stirs" the mix every time the lever is pumped.

I still don't know for sure which way to go. Since I already have a 25
gallon electric sprayer, maybe all I need is a 3 gallon hand sprayer as a
companion. Or maybe a backpack sprayer would last so much longer, it would
be worth the extra cost. I need to make up my mind. Spring is right around
the corner.
