Prosulfuron, rimsulfuron, thifensulfuron-methyl and tritosulfuron are widely used
sulfonylurea herbicides (SUs), applied in low-dose rates. However, these herbicides under
specific conditions as low temperature, poor rainfall, microbial activity. high pH of soil, can
remain at low concentrations in soil and can affect the growth of sensitive plants. This paper
presents the method that we developed for determination of prosulfuron, rimsulfuron,
thifensulfuron-methyl and tritosulfuron residues in soil. Determination and quantification
were performed by HPLC/DAD using Agilent Zorbax SB-C18 column (3.0 mm*250 mm. 5
um particle size). Mobile phase was acetonitrile/0.1% CH3COOH solution. Analyzed SUs
showed linear calibrations from 0.05 to 0.2 mg/ml with correlation coefficient (1°) above
0.990%. The recovery data were obtained by spiking blank soil samples at two concentration
levels (2.5-5.0 mg/kg), yielding average recovery between 95.56 and 99.79%. Precision
values expressed a...s relative standard deviation (RSD) were between 0.91-1.11% for all SUs
herbicides for the intraday precision. Considering the obtained values of analytical
parameters, the proposed method proved to be an efficient and sensitive method for the
determination of prosulfuron, rimsulfuron, thifensulfuron-methyl and tritosulfuron in soil
samples.
