Metabolism of Temik aldicarb pesticide [2-methyl-2-(methylthio)propionaldehyde O-(methylcarbamoyl)oxime] in the cotton plant

Metabolism of aldicarb pesticide in laying hens

“…No attempts were made to identify these metabolites. However, it is unlikely that the carbamate moiety was intact on these materials, since conjugation and/or degradation of aldicarb to alcohols and acids, processes which yield watersoluble metabolites, would be preceded by hydrolysis of the carbamate ester (Bartley et al, 1970). The unextractable radioactive metabolites, 8 to 10% of the residues, may be similar in chemical nature to the water-soluble metabolites.…”

“…Recent reviews of this subject (Dorough, 1970;Kuhr, 1970) pointed out that sulfur oxidation and hydrolysis of the carbamate ester were of major importance in the metabolism of this carbamate. Subsequent work supported this view and has extended the study of aldicarb metabolism to include the synthesis and identification of highly polar products not considered previously (Bartley et al, 1970;Durden et al, 1970). The metabolic pathway for aldicarb presented by Bartley et al (1970) is the most complete of any reported thus far.…”

The metabolic pathway for aldicarb presented by Bartley et al (1970) is the most complete of any reported thus far. It is likely that this pathway is representative of the type of metabolism which aldicarb undergoes in the other biological systems tested.…”

“…In addition, these investigations were designed to provide evidence for the levels and chemical nature in residues in eggs and tissues of hens which consume aldicarb residues in the diet. The sulfone analog was included since it is a common metabolite in plants which may serve as poultry feed (Bartley et al, 1970).…”

Uptake and Translocation of 2-<i>sec</i>-Butylphenyl <i>N</i>-Methylcarbamate (BPMC) in Cucumber and Komatsuna Plants

“…Metabolic fate of carbamates in plants has been examined using BPMC, MIPC, MTMC, carbaryl, aldicarb and so forth, [1][2][3][4][5][6][7][8][9] and those data demonstrated that the persistence of carbamates in plants was different with the plant species and carbamates. The study on the metabolism of BPMC in rice plants showed that BPMC was taken up rapidly and apt to translocate to the upper portions of plant.2) However, it is expected that the behaviour of BPMC in vegetable crops may be different from that in grain crops.…”
