Best sprayer?

I have no sprayer and need one (not for toxic stuff). First I which one, there are models for spraying trees were you use a bucket and others which
have a backpack. What is the best sprayer for both vegetables and trees the backpack thing or the bucket system?
Which brand do you recommend? It should be able to handle compost teas. And it should last long and be sturdy.

I've been making due with a cheap plastic one gallon sprayer. Now that my area has increased, I'm looking to upgrade. I'm tired of fixing/losing half of my contents anyways.

I've heard good things about Chapin Concrete Sprayers. They are well-made of metal parts, and don't clog. They run kinda expensive, but I hear they'll last for decades if cared for properly. I'm not sure about getting enough pressure for spraying very tall trees, but for veggies, pastures, and teas I hear they are perfect.

Thanks, the cheap sprayers are really a waste of money. I had one and it did not work after only one year.

I've had my plastic sprayer for a few years. I always rinse it out good, and I think that's why it's lasted so long.

I can't even tell you how many times I've gotten a face full of compost tea or kelp tea or whatever. I've had to fix the hose about 20 times in the middle of spraying and end up covered in whatever I'm spraying. My hose is about half as long as it used to be.

Good thing I don't use chemicals

I've used backpack sprayers pretty extensively. They work pretty well and even when full can be packed around for a couple hours without being too taxing on the body. They do require refill more often than I'd like. The nozzles can be a bit of a pain - but that's true of every sprayer I've encountered. Neem oil is particularly gunky and tends to clog up anything and everything I've had experience using. By and large - I'd say if you can find a backpack sprayer for 80-ish dollars It be worth the investment.
