A few months ago, I got a tip from Mr. Bonnie Childers, which has saved me a lot of money. The Mosquito 86 is a mosquito control device using a 1½-gallon backpack and a leaf blower to dispense mosquito pesticide. Well it turns out that this little device is really handy for spraying fruit trees. Its not a Solo 444 Motorized Mist Blower, but it gets the job done at a much more affordable price.If you run the leaf blower at high RPM you get a fog, but lower the RPM and you get larger droplets. It really works well for me and has saved $$$. The best thing about this gadget is that if you already have a leaf blower, then it is likely that they have an adaptor to fit it. Heres a link:
