“…3,[14][15][16][17][18] Very little studies on the fentrazamide residues in soil, crop, plant, animal and multi-residue have been reported. [19][20][21][22][23][24][25][26][27][28][29] No study has yet reported on dissipation of fentrazamide from the hot and humid sub tropical climate and Tarai region soils of Indian conditions. The proposed registration of fentrazamide for use is under consideration by Central Insecticide Board, DPPQS, India.…”

Dissipation of fentrazamide in soil and water under flooded (anaerobic) conditions was studied. Fentrazamide was applied to soil at 100 g ha(-1). Soil was extracted with 0.1 N HCl : acetone (1 : 1 v/v) followed by partition and cleanup with silica SPE. Separation was achieved in an ODS-II column with a mobile phase of acetonitrile : water (70 : 30 v/v) and detection at 214 nm. Recovery of fentrazamide varied from 75.2-90.4% and 89.9-97.8% in soil and water, respectively. Fentrazamide dissipated rapidly and fentrazamide residues were not detected after 100 and 35 days of application in soil and water, respectively. Half life in soil and water was 9.06 and 3.66 days, respectively. Dissipation followed monophasic first order kinetics pattern. No fentrazamide was detected in soil, rice grain and rice straw at harvest of crop. Calibration curves for quantification were linear and relative standard deviation (RSD) was 1.78%. LOD for instrument was 0.002 μg mL(-1) and LOQ for methods were 0.005 μg g(-1) for soil and water.

“…Differential absorption, translocation, and metabolism have been recognized as important factors contributing to herbicide selectivity (Usui 2008). Studies on fentrazamide residues in soil, crop, plant, animal and multi-residue are scare (Koester 2001;Sato et al 2001;Dubey et al 2003;Mukherjee and Gopal 2005;Lim et al 2008;Wang and Leung 2009;Wang et al 2010).…”

Dissipation of fentrazamide in soil under aerobic conditions was studied. Fentrazamide was extracted with 0.1 N HCl: acetone (1:1 v/v) followed by partition and cleanup. Separation was done on ODS-II column with mobile phase acetonitrile: water (70:30 v/v). Recovery varied from 74.51 % to 90.10 % percent in soil. Dissipation followed first order kinetics with monophasic pattern. Half life in soil was 9.02 days. Calibration curves were linear over the range of 0.05-1.00 μg mL(-1) and RSD was 1.82 %. LOD and LOQ were 0.002 and 0.005 μg g(-1) for soil. No residues in soil and crop were observed at harvest.
