What is Garden Dust?
It a multi-purpose insecticide fungicide made from basic copper
sulfate, rotenone and other cube resins from the rotenone plant. Rotenone
is a natural plant derived substance contained in the stems and roots of
certain tropical plants, such as the Jewel Vine or Flame tree (Derris
Spp.), or Lacepod (Lonchocarpus spp.). Rotenone is not a stable compound
and breaks down when exposed to light, heat, oxygen and alkaline water.
The breakdown process happens very quickly. Ultimately, rotenone breaks
down into two common substances; carbon dioxide and water. However it is
potent stuff.
