Dissipation of fuphenthiourea residues in rice and field ecosystem after seed soaking application
چکیده انگلیسی
An analytical method with SPE or matrix solid-phase dispersion clean-up procedure on PSA followed by HPLC-DAD was established for determination of fuphenthiourea residues in rice, water and soil. At three concentration levels (0.05, 0.5 and 5 mg kg−1), recoveries were in the range of 61.2-82.7%, with a RSD less than 13%. The LOQ of this method was 0.005, 0.02 and 0.01 mg kg−1 for the water, soil and rice samples, respectively. Fuphenthiourea was applied in supervised field trials at GAP conditions during rice seeding. It was found that under field conditions, the dissipation half-lives of fuphenthiourea were 0.8 d in the water and 24.8 d in the soil. At harvest, no detectable residues (
