Daminozide's production may result in its release to the environment through various waste streams; it's use as a plant growth regulator will result in its direct release to the environment. If released to air, a vapor pressure of 2×10-4 mm Hg at 23 deg C indicates daminozide will exist solely as a vapor in the ambient atmosphere. Vapor-phase daminozide will be degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals; the half-life for this reaction in air is estimated to be 32 hours. If released to soil, daminozide is expected to have very high mobility based upon an estimated Koc of 4. Daminozide has a pKa of 4.68 suggesting this compound will primarily exist as an anion in moist soils and water surfaces. Volatilization from moist soil is not expected since anions do not volatilize, and volatilization from dry soil surfaces is not expected based on the vapor pressure of this compound. In greenhouse studies, the persistence half-life of daminozide was found to range from 3 to 4 days in four different soils under aerobic conditions. Volatilization from water surfaces is not expected to be an important fate process because this compound will exist primarily as an anion in water and anions will not volatilize. No measurable hydrolysis of daminozide was noted at pH 5-9, but sensitized photolysis was observed, suggesting that photolysis in sunlit surface waters may occur. An estimated BCF of 3 suggests the potential for bioconcentration in aquatic organisms is low.     

Usage: Plant growth regulator reported by J. A. Riddell et al. (Science, 1962, 136, 391). Introduced by Uniroyal Chemical Co., Inc. (now Crompton Corp.) in c. 1965. Patents: US 3240799; US 3334991. Manufacturers: Crompton; Fine; Sannong; Tide. Biochemistry: Interferes with gibberellic acid biosynthesis.

Application: Absorbed by the leaves, with translocation throughout the plant. 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.
