The localization of 2,4-D in leaf tissue

Planta, 1970
Disruption of chloroplast structure is known to occur following applications of 2,4-dichlorophenoxyacetic acid (2,4-D) to the leaves of Phaseolus vulgaris. Although chloroplasts which had been extracted from treated tissue in an aqueous medium were free from 2,4-D and its metabolites, those extracted from freeze-dried tissue in organic solvents are the

The degradation of 2,4-D in forest litter

Bulletin of Environmental Contamination and Toxicology, 1967
These studies have shown that 2,4-D is rapidly degraded in forest litter and that the rate of degradation varies with the type of litter, herbicide formulation and the presence of DDT. The degradation of 2,4-D varies slightly in litter from different vegetation types when incubated under similar environmental conditions.

Evaluation of 2,4-D and 2,4-D Mixtures for Path Rush Control in Bermudagrass

Weed Technology, 2007
Path rush can become problematic on golf course fairways, especially on roughs where continuous golf cart or maintenance equipment traffic occurs. Research trials conducted in 2003 and 2004 compared the efficacy of 2,4-D and mixtures containing 2,4-D in single or sequential applications to herbicides without 2,4-D for path rush control in bermudagrass ...

Tolerance of cotton expressing a 2,4-D detoxification gene to 2,4-D applied in the field

Australian Journal of Agricultural Research, 2007
The tolerance to 2,4-dichlorophenoxy acetic acid (2,4-D) of a genetically modified (transgenic) cotton (Gossypium hirsutum) expressing a 2,4-D detoxification gene was compared with conventional (non-transgenic) cotton over 2 seasons. The 2,4-D was applied over-the-top of cotton in the field at 7–17 nodes of crop growth at rates of 0.004–1.12 kg a.i./ha.

Determination of 2,4-D Residues in Animal Products

Bulletin of Environmental Contamination and Toxicology, 1966
Several simplified methods for the analysis of pesticide residues in animal products have been reported recently from our Laboratory (1). The present communication is concerned with a rapid and convenient method for cleanup and analysis of high protein samples for the herbicide 2,4-dichlorophenoxyace-tic acid (2,4-D).

Leaf Ontogeny and Treatments with 2,4-D

American Journal of Botany, 1951
yielded both monocentric and polycentric offspring, indicating that they may be totipotent for both types. However, in these preliminary experiments the monocentric isolate yielded a preponderance of monocentric thalli, while the polycentric isolate gave rise to a greater number of polycentric thalli throughout 6 successive generations. The polycentric

The level of action of 2,4-D on transcription

Experientia, 1978
In mature cells, 2,4-D retards transcription when it is applied before 3H-uridine incorporation. But transcription is accelerated when it is applied after feeding with 3H-uridine. It has been suggested that the action of 2,4-D on transcription is only at the level of initiation.
