Garden dust Sprayer was received today and test operated using diatomaceous earth. It is advertised for powders and liquids. My use is primarily for powders. The unit was tested for operation for about ten minutes and performed to expectations. It is well made and the powder jet worked well in all orientations. It will be used during the growing season on cabbages and brussels sprouts and various garden plants as determined. Coverage appears to be possible for all areas compared to the limited hand method of dispersal. This is the one purchased. http://www.durgan.org/URL/?WZUEN Earthway Spritzer Duster Sprayer
