Abstract Click to copy section linkSection link copied! Few studies have examined the environmental fate of quinotrione, a new type of 4-hydroxyphenylpyruvate dioxygenase (HPPD)-inhibiting herbicide in plants. In this study, the uptake, translocation, and metabolism of quinotrione in pak choi were explored using 14C-labeling method and high-resolution mass spectrometry. The results showed that 57.7% of 14C-quinotrione was accumulated by pak choi via foliar application.
