ENVIRONMENTAL FATE

2,4-D isooctyl ester's former production may have resulted in its release to the environment through various waste streams; it's use as a systemic herbicide will have resulted in its direct release to the environment. If released to air, a vapor pressure of 7.06×10-6 mm Hg at 25 deg C indicates 2,4-D isooctyl ester will exist in both the vapor and particulate phases in the ambient atmosphere. Vapor-phase 2,4-D isooctyl ester 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 33 hrs. Particulate-phase 2,4-D isooctyl ester will be removed from the atmosphere by wet and dry deposition. Solutions of 2,4-D isooctyl ester absorb light > 290 nm, suggesting 2,4-D isooctyl ester may be susceptible to direct photolysis by sunlight. If released to soil, 2,4-D isooctyl ester is expected to have essentially no mobility based upon an estimated Koc of 29,000. Volatilization from moist soil surfaces is expected to be an important fate process based upon an estimated Henry's Law constant of 5.7×10-5 atm-cu m/mole. However, volatilization from moist soil surfaces is expected to be attenuated by adsorption to soil. In soil, the hydrolysis of 2,4-D isooctyl ester to 2,4-D and the alcohol was suggested to be microbially mediated. 2,4-D isooctyl ester was not detected after 3 years at an initial concentration of 560 ppm and application rate of 1,280 kg/ha. If released into water, 2,4-D isooctyl ester is expected to adsorb to suspended solids and sediment based upon the estimated Koc. Biodegradation is expected to be slow in water. Volatilization from water surfaces is expected to be an important fate process based upon this compound's estimated Henry's Law constant. Estimated volatilization half-lives for a model river and model lake are 20 hrs and 15 days, respectively. However, volatilization from water surfaces is expected to be attenuated by adsorption to suspended solids and sediment in the water column. An estimated BCF of 31,000 suggests the potential for bioconcentration in aquatic organisms is very high. However, like 2,4-D butyl ester, 2,4-D isopropyl ester may also be readily metabolized in fish and therefore should not bioconcentrate. 2,4-D isooctyl ester is expected to hydrolyze in solution. In distilled water, over 90% was recovered unchanged after 5 hours; this corresponds to a half-life of approximately 33 hrs. Hydrolysis of 2,4-D isooctyl ester to free anion in 0.1 N sodium hydroxide (pH 13.0) was almost instantaneous. Occupational exposure to 2,4-D isooctyl ester may have occurred through inhalation of aerosols containing 2,4-D isooctyl ester during spraying operations and dermal contact with sprayed vegetation.

Usage: Selective post-emergence foliar treatment herbicide.

Application: Using 50% EC, 990-1320 mL/ha to control the broad-leaved weeds in the wheat field. Used to control the broad-leaved weeds in corn field, and the soil spraying was carried out by using 50% EC 1290-1830 mL/ha. To prevent and control weeds in soybean field, the soil spray was carried out with 50% EC 1140-1350 mL/ha.
