This clay is mixed in water to form a slurry that is sprayed on the fruit. The insects can't stand the feel of it, it annoys them so they avoid the areas that are sprayed. Organic gardeners use this to control insects without poisons. I googled this and could find very little information on sprayers that would not clog with wettable powders. My cousin told me about the SP Systems SPO sprayer and said that might work. So I took a gamble and bought this sprayer.Another concerned was whether pumping up the pressure would be difficult. Some sprayers I tried in the past were a real challenge to your arm strength and a royal pain.I am happy to report that this sprayer is fantastic and it works flawlessly with "Surround WP". Also, the pump travel is only about 6" and it is so easy to pump, requiring hardly any effort. You do not need to remove this backpack sprayer from your back to pump it. The pump handle sticks out near your left elbow and pumps with an easy downward motion. It pumps up surprisingly fast - a quick 20 pumps and it is ready to go. Not only that, but each pumping action stirs the mixture so the powder does not settle. The directions say to give it a pump every 5 seconds to stir the mixture. I thought that would be a hassle, but it is so easy, and a non-issue.One thing, for those of us that don't read directions, the directions say to put a light coat of oil on the cover gasket to prevent air leaks. I used a Q-Tip to apply some mineral oil. That worked well - no leaks. This needs to be done each time you use it.It comes with four different sprayer nozzles. I like the adjustable brass nozzle for "Surround WP". You can adjust the spray from wide to narrow and the distance it travels from a few inches to about 20 feet. The greater the distance, the narrower the spray.Being a backpack sprayer, it is so easy to climb my orchard ladder with my hands free. No canister to lug around and juggle.It is a 4-gallon sprayer. My concern was if I only wanted to spray one-quart would it work. The answer is yes. You could put in just one cup and it will work until that one cup is gone. It turned out I needed about 3 quarts to spray 24 young fruit trees and a large fruit tree.Cleaning is easy. Put some fresh water in a couple of times and sprayed it out. I found cleaning went much faster if I removed the nozzle.I never imagined spraying could be so easy. I was pleasantly surprised and I highly recommend this sprayer for use with "Surround WP". ### ⭐ 1.0 out of 5 stars Very disappointed with the product. *by H***R on Reviewed in the United States on January 1, 2014* I used it very lightly and started leaking after few times. I contacted the manufacturer and they refused to send me the defective part.I would not recommend to this pump and it is over priced since the OEM does not stand behind the products. I am very disappointed ### ⭐⭐ 2.0 out of 5 stars no parts *by G***1 on Reviewed in the United States on May 24, 2015* hard to find parts --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.at/products/18403245-model-100-triple-function-backpack-sprayer](https://www.desertcart.at/products/18403245-model-100-triple-function-backpack-sprayer) --- *Product available on Desertcart Austria* *Store origin: AT* *Last updated: 2026-04-27*
