2,4-D Amine Salt
    2,4-ΰ
Introduction: 2,4-D Amine Salt is a selective systematic post emergent herbicide. It is in liquid state and does not require long time for stirring. It is fully soluble in all proportions and therefore is well adopted to low gallonage spray equipment, even at high rates of application. It is a safe herbicide in connection with accumulation in soil and phytotoxicity. Being highly soluble in water it leaches more faster than the mineral salts of 2,4-D and is then absorbed by the soil organic matter or clay colloids.

MAMMALIAN TOXICOLOGY
Acute toxicity: 1) Acute oral LD50 for rats is 300-2000 a.i.mg/kg. 2) Acute dermal LD50 for rats is >2000 a.i.mg/kg. 3) Acute inhalation toxicity LC50 (4 h) for rats is >5.06 a.i.mg/L. 4) Skin irritation: Non-irritating to skin (rabbits). 5) Eye irritation: Non- irritating to eyes (rabbits). 6) Skin sensitization for guinea pig: Not sensitising.
ECOTOXICOLOGY
Effect on birds: Acute oral LD50 for Mallard is >5620 a.i.mg/kg. Effect on fish: Acute LC50 (96 h) for Rainbow trout is 100 a.i.mg/l. Effects on aquatic invertebrates: Acute EC50 (48 h) for Daphnia magna is >100 a.i.mg/l. Effects on algae: Acute 72 hour EC50 for Pseudokirchneriella subcapitata is >60.7 a.i.mg/l.
ENVIRONMENTAL FATE
If released to air, an estimated vapor pressure of 2.310-9 mm Hg at 25 indicates 2,4-D dimethylamine will exist solely in the particulate phase in the ambient atmosphere. Particulate-phase 2,4-D dimethylamine will be removed from the atmosphere by wet and dry deposition. If released to soil, 2,4-D dimethylamine is expected to have high mobility based upon a range of Koc values from 72 to 136. Volatilization from moist soil surfaces is not expected to be an important fate process based upon an estimated Henry's Law constant of 1.410-16 atm-cu m/mole. Biodegradation is the primary degradative pathway in the soil with half-lives ranging from 4-6 days and 7-23 days in agricultural and forest soils, respectively. If released into water, 2,4-D dimethylamine salt is not expected to adsorb to suspended solids and sediment based upon the Koc. In a river-die away study, a half-life of 3.9 days was obtained for an unspecified amine salt of 2,4-D. 2,4-D dimethylamine is rapidly degraded by aquatic microorganisms in activated sewage. Volatilization from water surfaces is not expected to be an important fate process based upon this compound's estimated Henry's Law constant.
Usage: 2,4-D Amine Salt was covered in The Hormone Weedkillers, C. Kirby. It is a translocated phenoxy herbicide for use in cereals, grass and amenity use.
Application: Biochemistry Synthetic auxin (acting like indolylacetic acid). Mode of action Selective systemic herbicide. Salts are readily absorbed by the roots, whilst esters are readily absorbed by the foliage. Translocation occurs, with accumulation principally at the meristematic regions of shoots and roots. Acts as a growth inhibitor. Uses Post-emergence control of annual and perennial broad-leaved weeds in cereals, maize, sorghum, grassland, established turf, grass seed crops, orchards (pome fruit and stone fruit), cranberries, asparagus, sugar cane, rice, forestry, and on non-crop land (including areas adjacent to water). Control of broad-leaved aquatic weeds.
