Lime Sulfur Purpose:
Lime sulfur is sold as a spray for deciduous trees to control fungi, bacteria and insects living or dormant on the surface of the bark. Lime sulfur burns leaves so it is not as useful for evergreen plants. Bonsai enthusiasts use undiluted lime sulfur to bleach and sterilise portions of trees to give an aged look known as Jin. Diluted solutions of lime sulfur (between 1: 16 and 1: 32) are also used as a dip for pets to help control ringworm. (Note that undiluted lime sulfur is corrosive to the skin and will cause serious injury.)
