The effect of 2,4‐dichlorophenoxyacetic acid on laying hens

British Poultry Science, 1972
Synopsis Laying hens were fed 2,4‐D, a herbicide, at a rate equivalent to 50 and 150 mg/kg diet from age 28 to 48 weeks. No adverse effects of the treatments were observed upon rate of egg production, egg or yolk weight, egg shell thickness, hatchability or growth rate of the progeny.

Confirmed 2,4-Dichlorophenoxyacetic Acid Toxicosis in a Dog

Journal of the American Animal Hospital Association, 2010
A 2-year-old, intact male Weimaraner was evaluated for episodic extensor rigidity and a stiff gait of 24 hours’ duration. Percussion of the proximal appendicular muscles with a reflex hammer resulted in formation of dimples consistent with myotonia. Electromyography identified myotonic potentials. Residues of 2,4-dichlorophenoxyacetic acid (2,4-D) were

The disposition of 2,4-dichlorophenoxyacetic acid in rainbow trout

Archives of Environmental Contamination and Toxicology, 1983
This study investigated the dynamics of 2,4-dichlorophenoxyacetic acid (2,4-D) in Salmonid fish. Similar to mammals and marine fish, trout excrete 2,4-D via the urine, with an elimination half-life of 2.4 hr. Although the amount of 2,4-D found in bile was always less than 1% of the dose, the concentration of 2,4-D in bile was greater than any other ...

Absorption and Excretion of 2,4-Dichlorophenoxyacetic Acid in Man

Xenobiotica, 1974
Abstract1. Absorption and urinary excretion of 2,4-dichlorophenoxyacetic acid (2,4-D) have been studied in six subjects following oral ingestion (5 mg/kg).2. 2,4-D is quickly absorbed; significant quantities were detected in plasma 1 h after ingestion.3.

Poisoning with 2,4-dichlorophenoxyacetic acid treated by hemodialysis

Archives of Toxicology, 1992
In this paper four patients are presented who had been poisoned by 2,4-dichlorophenoxyacetic acid (2,4-D). The first patient, aged 51 years, had attempted to commit suicide by taking orally 400 ml of a 40% solution of 2,4-D. He was admitted in a coma, 6.5 h after poisoning.

2,4-Dichlorophenoxyacetic Acid

2000
Abstract 2,4-Dichlorophenoxyacetic acid (2,4-D) is one of a group of chlorophenoxy compounds widely used as herbicides. The chlorophenoxy herbicides act as synthetic auxins (plant hormones) that alter the metabolism and enhance the growth of plants. The abnormal growth interferes with the transport of nutrients and destroys the plant.

The Microbial Degradation of 2,4-Dichlorophenoxyacetic Acid in Soil

1988
The herbicide 2,4-dichlorophenoxyacetic acid (2,4-D) and the related 2,4,5-trichloro- and 2-chloro-4-methylphenoxyacetic acid (2,4,5-T and MCPA, respectively), are selectively highly toxic to most annual and perennial dicotyledonous species and relatively nontoxic to monocotyledonous plants (Loos 1975a).

Absorption and Translocation of 2,4-Dichlorophenoxyacetic Acid

Botanical Gazette, 1946
1. The pronounced morphological response in plants to 2,4- dichlorophenoxyacetic acid is useful in studies of translocation. 2. The regulator passed upward but not downward through dead segments of stems. 3. Stomata did not appear to be important portals for entry of the compound into the leaves when it was used in aqueous sprays.

2,4-Dichlorophenoxyacetic Acid as a Differential Herbicide

Botanical Gazette, 1944
1. 2,4-Dichlorophenoxyacetic acid was effective as a differential herbicide when applied as an aqueous spray in concentrations of from 250 to 1000 p.p.m. or more. 2. Plants killed by these sprays were dandelion, narrow-leaf plantain, Dutch white clover, chickweed, pigweed, woodsorrel, knotweed, broad-leaf dock, bind-weed, and shiny pennywort.
