Abstract
A nozzle and sprayer system for aerosolizing liquid for its even application to foliage. The frustoconical nozzle housing body defines a longitudinal axis, a wall, a proximal portion, and a distal portion, the housing wall at the distal portion being thicker than the housing wall at the proximal portion, and an air chamber defined by the housing wall of the proximal portion. The housing also defines a plurality of tapered air conduits that are spirally and radially arranged about the longitudinal axis that create a vortex in expelled air. The housing also defines a liquid conduit defining a bend. The outlets of the plurality of air conduits are radially arranged about the outlet of the liquid conduit, such that fluid ejected from the outlet of the liquid conduit into the vortex is sheared to create a fog or mist of small liquid particles suspended in air.
