| Hazard Information | Back Directory | [Chemical Properties]
Crystalline Solid | [Uses]
Auxin-type herbicide | [Definition]
ChEBI: A quinolinemonocarboxylic acid that is quinoline-8-carboxylic acid carrying additional methyl and chloro substituents at positions 3 and 7 respectively. A residual herbicide used to control broad-leaved weeds on a range of crops including cereals, rape and
beet. | [Uses]
Herbicide. | [Environmental Fate]
In the field, the DT50 of quinmerac
may range from 3 to 33 days. Losses due to volatilization
are negligible. Soil moisture conditions greatly influence
quinmerac persistence by moderating microbial degradation
and soil leaching. Quinmerac is only slightly adsorbed
to the soil. | [Metabolism]
Chemical. Quinmerac is stable to heat, light, and in
aqueous solutions with pH values between 3 and 9.
Plant. The degradation and metabolic pathways of
quinmerac have not been extensively studied. In plants,
oxidation of the 3-methyl group to the alcohol and
hydroxylation at the 2-quinoline position are the major
metabolism reactions (56). These quinmerac metabolites
are subsequently conjugated to carbohydrates. The
quantity of quinmerac metabolized varies among species,
ranging from 5% to 80% (56).
Soil. In the soil, degradation of quinmerac was similar
to that observed in plants, resulting in the same
oxygenated and hydroxylated metabolites. | [Toxicity evaluation]
Quinmerac is excreted in the urine
of mammals and appears to remain primarily unmodified.
The acute oral LD50 in rat is >5000 mg/kg. |
