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 kgâ1), 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 kgâ1 for the water, soil and rice samples, respectively. Fuphenthiourea was applied in supervised ï¬eld 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 (
