Field sprayers and crop dusters have no way to control drift. When our copper ionization units is hooked up to either one, you will immediately see the reduction in drift. Not only are you reducing drift but you are applying a positive charged slurry mix to a negative site which is the leaf and under the canopy. Under the canopy is where most problems start, the positive charged copper ions will attach to these pathogens killing them and leave a protective barrier on the stems, leaves and product. The copper ions will slowly descale the tank, pipes and nozzles and maintain the equipment. You now will be able to reduce the copper based fungicides you are using by 40%.
