Carbaryl is also on the Proposition 65 list because it can cause birth defects or other reproductive harm. The aryl hydrocarbon receptor (AhR) is a ligand-dependent transcription factor that mediates many of the biological and toxicological actions of a variety of hydrophobic natural and synthetic chemicals, including the environmental contaminant 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD, dioxin).

Although its mode-of-action is not fully understood, directions for its use have been carefully defined, and it is now used widely because it is very effective and reliable as a fruit thinning agent for the major cultivars grown in the UK. Our results confirm that carbaryl is both a weak AhR ligand and inducer of AhR-dependent gene expression and argue against its proposed ligand-independent mechanism of AhR activation.

Environmental Toxicology and Pharmacology. Avoid life-threatening adverse drug events & improve clinical decision support. Documents related to EPA's review of this pesticide can be found in the following docket(s): Soil microbes (bacteria and fungi) are capable of degrading carbaryl; the process is more rapid in anoxic than aerobic systems and with increased temperature and moisture. This map represents the area potentially directly and indirectly affected by the federal action141 Figure 21. What this means in everyday language is that when a pest comes in contact with the chemical through skin absorption or digestion, the carbaryl directly attacks the nervous system, causing death. Rapid population growth and, consequently, growing demand for food have increased the use of pesticide to have higher yield for crops and other agricultural products. Carbaryl is hydrophobic in nature and retains on Coresep 100 mixed-mode column by reversed-phase mechanism. Sorption of the insecticide to soil is kinetically rapid. The oral LD 50 is 250 to 850 mg/kg for rats and 100 to 650 mg/kg for mice. ACCORDING TO MODE OF ACTION IRAC* GROUP DREXEL PRODUCT (BRAND NAME) REG.

Carbaryl belongs to the N-methyl carbamate group of pesticides, which share a common mechanism of toxicity. After contact with or ingestion by aquatic organisms, the toxic mode of action of carbaryl is inhibition of . Eleven reaction channels have been identified using the density functional theory. The FQPA requires EPA to consider cumulative risk for pesticides that share a common mechanism of action before completing tolerance reassessment for individual chemicals in the common mechanism group, hence the interim decision. The stability of carbaryl in water was enhanced by low pH and low temp.
