Embodiments provide an applicator configured to pressurize and heat a mixture of water and herbicide, and expel the heated and pressurized water/herbicide mixture from the applicator. In some embodiments, the herbicide may be an organic herbicide such as organic acids, simple sugars, surfactants, or ammonia. The applicator may include an inline heating element coupled with a spray tip of the applicator such that the inline heating element may receive a water/herbicide mixture from a water line of the applicator, heat the water/herbicide mixture, and then supply the water/herbicide mixture to the spray tip.
