MOW ED The hose end sprayer is a Gilmour # 362-D. I found it, if I remember right, at thier web site, try http://www.gilmour.com I ordered it thru my local Ace Hardware. I have seen it also at Amazon.com in the lawn and garden tools section. It only cost about $16.00. In a world where professional or commercial use usually means expensive, I know this makes it sound so much more like non-professional type equipment. It's metering is designed to work at 40-60 psi. The meter comes with a needle for teaspoons and one for tablespoons. It will meter/mix up to 10 of either. Most mixtures I use are in the 1-3 oz ranges(2-6 tablespoons per gallon of water). The bottle only holds about 20 ounces. So, before everyone goes crazy about filling several carrier bottles and the time involved, etc.. I sprayed a 3 acre property entirely - filled the jug 5 times. Yes, this can be a time consuming issue, but I do not spray enough for this to be any major problem. After one spray, the 3 acres are now under control to where I only spot spray, never using more than a few gallons of total mixture, a few ounces of pesticide. Most of my maintenance properties are less than 15,000 sq ft and are the same, I do not spray weed free grass just as a precaution. I know this may not work for many of you big sprayers, but it works great for me. I thought about finding a bigger bottle for bigger jobs, But so few a times that I would need it that I have not stressed about it. I did go big on the sprayer end. I purchased a 200 gallon skid sprayer from Westheffer. 300 foot high grade hose and rewind reel, 5.5 Honda, 9.5 gpm, 550 psi pump. I slide it up into a 1 ton dump truck and dump it out when I am done. I could have gotten cheaper one, but this one is well made. They do make a 12 volt setup for about have as much which could have worked for me just fine, but I wanted the bigger model just incase I needed it later down the road. I have sprayed Dormant Oil, Hort Oil, Strike Three, Trimec, Trimec plus, Roundup, Volk Oil, Weed-B-Gon, Ornimec, Malathion, and Sevin. Any chemical heavier or thicker than water needs to be prediluted, information with the Gilmour sprayer tells how. I have sprayed Dormant Oil, Strike Three, and Sevin at one property, all in one visit with one sprayer, plus granular fert that visit as well. Just thought, I also watered some shrubs and flowers another visit later in the year, Do that with a tank mix. Filling the bottle onsite and the occassional dilution is of course a draw back if you were doing alot of spraying. But for what little I do it works great and the time is worth it knowing that I wasted no chemicals and I am being safe for my nieghbors childern and my own by only running water in my tank 100%. For the small spraying company like myself, the versitility is what is nice. I plan on adding some PGR's next year and I some fertilizer while watering a few patches of flowers and goundcover. Hope this book helped.
