Application

Daminozide interferes with gibberellic acid biosynthesis. Mode of action Absorbed by the leaves, with translocation throughout the plant. Used To produce more compact plants (by inhibition of internodal elongation) of chrysanthemums, azaleas, hydrangeas, poinsettias, and other ornamentals. Applied at 0.106–0.425 kg/ha. Daminozide is banned to use on food crops.
