Hi there, I am curious about the difference between lime sulfur and plain sulfur. I know that regular sulfur that can be bought in powder form can be use for a variety of plant afflictions, but what does the 'Lime' part do when we use Lime Sulphur in our dormant sprays? Does it do additional things that benefit the plant health? Is it a surfactant? Only out of curiousity but I can't find this info anywhere!!! Thanks, Robyn
Lime sulfur is obtained by reacting calcium hydroxide, commonly called slaked lime or hydrated lime, with sulfur. Hence the word 'lime' in Lime Sulfur. Both, elemental sulfur and lime sulfur are used as organic fungicides and insecticides. Both benefit the plant health by killing pests. Elemental sulfur is also used to decrease pH of the soil.
