Technical Bulletins
The phytotoxicity of bauxite, cement flue, mud lake, alumina and kaolin dusts were examined on tomatoes. Mud lake white dust caused severe leaf scorch, affected plant growth and resulted in no harvestable yield. Flue dust applied daily depressed market yield of fruit from 64 t ha to 42 t ha. Flue dust applied at 3.1 t ha had no effect. There was no phytotoxic effect from bauxite, alumina or kaolin.
