| الوصف: | The metabolism of 14C-penfluron (2,6-difluoro- N -[[[4-(trifluoromethyl)phenyl]amino]14C-carbonyl]benzamide) was studied in Anthonomus grandis grandis Boheman. Recoveries of radioactivity of 99 and 94.36% were obtained after 4 days and 1 week, respectively, from weevils that had been injected with 124,970 dpm (4.61 μg/weevil). On the basis of the total injected amount, 97.74% of the label recovered from the extract of weevils 4 days posttreatment were unchanged penfluron and 0.16% was conjugates. Similarly at 1 week posttreatment, 90.56% were unchanged penfluron and 0.2% was conjugates. Less than 1% of additional radioactivity was recovered from weevil residues in both experiments. Four days posttreatment, recovery from excreta extract was 1.02%; 0.33% was unchanged penfluron; 0.06% was 2,6-difluorobenzamide; and 0.63% was conjugates. Similarly, at 1 week posttreatment the recovery from excreta extract was 3.41%; 1.33% were unchanged penfluron; 0.20% was 2,6-difluorobenzamide; and 1.87% were conjugates. The conjugates consisted of 2 metabolites which upon acid hydrolysis yielded a single relatively nonpolar metabolite that was assumed to be a hydroxylated derivative of penfluron. |
