This experiment was carried out to study the absorption of Quizalo-p-tefuryl in soil. Different amount of Quizalo-p-tefuryl was put into soil of 5g. They were shaken at 25±2℃ for 24 hours and then centrifuged at 4 000 r/min for 20 min. The supernatant was filtered and analyzed by HPLC. The absorption of this herbicide was increased as the content of organic matter rose and the correlation meet with Freundlich formula.
