[NAFEX] backpack sprayers

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.
