  • Patent number: 5402945
    Abstract: An improved method for row crop spraying whereby a solution is atomized by high speed air, imparted with an electrical charge, slowed with more high speed air, and deposited over crops including a nozzle for practicing such a technique. Such charged droplets are attracted to oppositely charged crops and are, therefore, more likely to adhere to crops than fall to the ground or to be swept away by the wind. Since a larger percentage of solution adheres to the plant, less solution can be applied thereby addressing both environmental and pecuniary concerns.
