Abstract: A spraying nozzle, system, and associated methods for applying a liquid to foliage are provided. A container having an opening supplies liquid to be sprayed to a nozzle that includes a spray tip at an upstream end. The nozzle is made of an inert material, and a magnet is affixed adjacent the spray tip's orifice along the liquid pathway. The liquid is pumped out of the container, passing by and contacting the magnet, which affects the liquid droplets by orienting the dipoles of the molecules comprising the liquid. This serves to reduce the droplet size owing to mutual repulsion, creating a “cloud” of spray. The smaller droplets are better able to penetrate smaller spaces in the foliage such as insect habitats and difficult-to-access foliage pockets. The transient magnetization also increases the attraction of the droplets for the foliage, which thereby further increases the efficiency of spraying and coverage achieved.
