In the present study, a single residual analytical method was developed for pyraclofos. Pyraclofos was analyzed in brown rice, soyabean, green pepper, and mandarin. For pyraclofos, samples were extracted with acetonitrile, concentrated and partitioned with dichloromethane and analyzed with GC/FPD. The limit of quantitation (LOQ) for fosthiazate was 0.1 ng (S/N>10) and method limit of quantitation (MLOQ) was 0.02 mg/kg. Recovery ranged through 78.1%-117.7% at fortification level of 0.02 (MLOQ), 0.2 (10×MLOQ), and 1.0 (50×MLOQ). The coefficient of variation (CV) for both the pesticides was less than 10% regardless of sample types. These results were further confirmed with GC/MS, respectively.

In the present study, a single residual analytical method was developed for fosthiazate. Fosthiazate was analyzed in brown rice, soybean, green pepper, and mandarin. For fosthiazate, samples were extracted with acetonitrile, concentrated and partitioned with dichloromethane and analyzed with GC/FPD. The limit of quantitation (LOQ) for fosthiazate was 0.1 ng (S/N>10) and method limit of quantitation (MLOQ) was 0.02 mg/kg. Recovery ranged through 80.7-111.3% at fortification level of 0.02 (MLOQ), 0.2 (10×MLOQ), and 1.0 (50×MLOQ). The coefficient of variation (CV) for both the pesticides was less than 10% regardless of sample types. These results were further confirmed with GC/MS, respectively.
