    Guys this should be pretty simple, I hope

    Every time I use it my sprayer seems to "pump differently" I don't know how to describe it other then you know how a 4 gallon backpack sprayer pumps when you get empty and sticks when you pump while empty?

    That's what Eagle 20 does the entire 4 gallon, off/on kind of pump

    Anything I can do for this?

    Thanks in advance

    Hard to make backpacks spray consistent enough to apply fungicides I would think and it would be hard to get the volume you need for fungicides. You may have clogged strainers & filters or nozzles. They make pressure regulating devices for backpacks but don't know how much that would help you in this situation.

    Eagle 20 EW although a good all around broad spectrum fungicide is a flowable formulation and like all flowable
    Materials they are micro clay based and need good agitation to stay suspended. A good method that I utilize is to mix the material at the volume needed ( with a back pack usually between .5 gal to 1 gal spray volume ) in the truck tank with the sparge agitators then fill the back pack from the spray gun with the tip off, then its ready to go. I usually use a secondary tank ( have a split tank set up ) on the truck. Depending on what I need for the day I usually fill the tank with between 15 - 30 gallons, I don't use the hose because most of the time there are only a couple hundred square feet to maybe 1000 of disease pressure on the properties as I traverse through the day.

    When I used to use manual sprayers, everything was mixed in an old 21/2 gallon jug. Put in water, add product concentrate, cap it, and shake the heck out of it. I would then pour the mix through a fine mesh strainer into the tank. My power sprayers all have fine mesh basket screens at the tank openings and there are even finer screens behind the tips.

    Yes, my sprayer has the pressure regulator on it, mix 4 gallon at a time and since I'm walking that 4 gallon stays mixed. Never had a problem but I'm only applying to my own property. Not commercial.

    My sprayer has 4 filters in it, I clean them after every use. :drinkup:

    Again, this only happens when spraying Eagle, no problem with Clearys or Heritage. No problem spraying insecticides or other fungicides for fruit tree's.

    Problem is hard to explain I guess, I don't think anyone understands yet.

    Its like the pump needs to be oiled or greased. It wants to stick when I pump; does this make better sense?

    Now it does. Maintenance on a manual sprayer is just as bad as a power sprayer. The plunger cup on the pump needs to be kept greased with silicone grease as in what is used on faucet O rings.

    I'll check the manual and see how to get to this and grease, but why doing it while only spraying one product?

    Eagle 20

    Anything else I put in it sprays like a charm?
