Mechanism of Action
WHEN THE GROWTH OF PEA PLANT WAS RETARDED BY IN VIVO TREATMENT WITH 10-3 MOLAR PHOSPHON D THE CONTENT OF GIBBERELLIN-LIKE SUBSTANCES INCR IN THE SURFACE ORGANS & DECR IN THE ROOTS.
PHOSFON D INHIBITS MOSTLY THE SYNTH OF PROTEINS INVOLVED IN GROWTH. KNYPL JS; FLORA (JENA), ABT A; 160 (3): 217 (1969). PHOSPHON D INHIBITED BOTH SYNTH & DEGRADATION OF PROTEIN. INCORPORATION OF URACIL INTO RNA WAS INITIALLY INHIBITED & THEN STIMULATED IN KALE.

CHLORPHONIUM CHLORIDE IS USED AS HEIGHT RETARDANT FOR LILIES & CHRYSANTHEMUMS. IT IS ALSO EFFECTIVE IN RHODODENDRONS. IT IS MOST EFFECTIVE AS SOIL TREATMENT FOR POTTED PLANTS.
Applications
DescriptionChlorphonium chloride is an obsolete plant growth regulator that was used largely on ornamentals. It has a high aqueous solubility but is non-volatile. It can be very persistent in soil systems. Little data is available regarding its toxicity to biodiversity. It has a moderate mammalian toxicity and is a skin and eye irritant.
