Metabolism of the fungicide triforine in barley plants

摘要

AbstractThe metabolic fate of 3H‐triforine in barley plants has been studied. 15 and 30 days after treatment, unchanged triforine amounted to 57.5 and 43.2 respectively, and of three soluble metabolites detected, piperazine (0.3 and 4.0) and N‐2, 2,2‐trichloro‐1‐(piperazin‐1‐yl)ethylformamide (12.9 and 8.4), the latter for the first time as a metabolite in plants, were identified using t.1.c. with four solvent systems. The solid residue contained 23.1 and 38.2 of bound label after 15 and 30 days
