Does anyone know if any company makes a hose-end sprayer that I can put my own spray nozzle on? I'm talking about a unit that you dump your bug spray in the jar and dial the dosage on the lid. Quite a few years ago I had one that I could put my watering wand and spray out of that. It did a croaker, and I don't remember the brand name. And of the units out there today have such a crappy spray pattern on them that it's hard to get good coverage. I'd sure like one of those again. I see that some of my plants still have whiteflies on them and I'd like to spray them good before greenhouse time. When I spray in the greenhouse I just dump my bug dope in the watering tank since I have gallon markers on the tank and can just add the appropriate amount of the concentrate. I can use my decent hose nozzle that gives me great over-all plant/leaf coverage. So what I am wanting is something I can use now while the plants are outside.

Thanks in Advance.

I don't think they make them anymore. But ... you could probably hack one.

I discovered that the nozzle end of my ortho dial n spray pulls off easy. What's sticking out is about 1/2 inch wide. Find a pvc adapter that will fit over what's sticking out to whatever size hose you are using, say 5/8 inch. You want the larger end to be threaded.

You'll need to use a heavy duty glue like a 2 part epoxy specifically for plastic to attach the adapter to the hose end sprayer. I think this would work for you.

I'll have to see if I have an Ortho sprayer up in my g'house stash.

Thanks.

You might try other sprayers like the ortho and see if the nozzle comes off .. if it does then take the top part to lowes or home depot so you can make sure you get an adapter that fits .. if you find one that 'almost' fits, you can ream out the inside with a dremel to make it fit.

I don't have an Ortho, and the other ones have ends that look to be pretty secure on there; I'd probably bust something.

Do you have a "mixer"? Like a siphon that pulls 1/20th as much as the volume of water flowing through it?

You can attach that between a hose end and any nozzle you have, but you might have to carry the bottle of concentrate in one hand and the hose in another.

Like:
Hozon Siphon Mixer
http://www.hozon.com/
I paid $18 for one.

I think it is designed for high-flow-fertilizer injection, but might work for adding a 20X concentrate of bug-spray.

I don't know of an injector that can be dialed down to, say, 1:1 mixing.

All these except the $348 one assume you will be injecting fertilizer into a hose and then irrigating with it. I don’t know for sure if they would work near the hose end with low flow rates. “3 GPM” sounds like a lot more than a hand sprayer puts out.

Also, they mix at least 19 or 99 parts water to one part concentrate. Would your bug spray need to be much less concentrated?

Here’s a good review article that makes the E-Z Flow option above sound good.

http://www.noble.org/ag/hortic...
Most commercial injectors ...
“... are designed to be coupled with watering wands and sprinklers having flow rates of 3 gallons per minute (gpm) or higher”

“consider using a Grow Pro brand injector which costs around $30. Unlike the siphon mixer, the Grow Pro has a built-in 12-ounce reservoir”

“EZ FLO injectors .. . The 3/4-gal model is priced around $70”
The article also mentions a clunky DIY injector “assembled from a new or used pump-up hand sprayer and a few pipe fittings for under $50”

I bought one of those siphon thingies many years ago, it was a waste of money because I have 150-200 feet of hose and that is too long for it to work. I'm thinking that Xerantheum's idea is the most cost-effective for me. I will look for an Ortho apparatus (??) tomorrow when I'm in town and I'll have the SU along for him to find that adaption I will need.

Hee hee, totally OT, but....."SU?" Does that stand for "Significant Underling?"

Oh, now THAT'S a good one. No, "Spousal Unit".

A bit off topic, but have you seen this?
