Oxamyl is a carbamate pesticide used to control nematode in protected crops and potato cultivation (1). Oxamyl metabolites are useful compounds to characterize omxamyl-degrading microbes and to investigate metabolic pathway of Oxamyl. Oximino Oxamyl is a metabolite of Oxamyl (O845140) in apple, orange, and tomato (2,3).
