Metabolism of [¹⁴C]cymoxanil in grapes, potatoes and tomatoes

Abstract

Abstract Foliar‐applied [ 14 ]cymoxanil, 1‐(2‐cyano‐2‐methoxyimino‐[2‐ 14 C]acetyl)‐3‐ethylurea was rapidly metabolised in grapes, tomatoes and potatoes, Furthermore, the metabolism of this fungicide was unusual in that the metabolites were found to be naturally occurring compounds, with glycine as the major metabolite. Significant levels of radioactivity were found in other amino‐acids, sugars, starch, fatty acids and lignin, indicating incorporation of carbon‐14 via the various metabolic pathways.
