To analyze pesticides are Chlorothalonil, Pyridaphenthion, Azoxystrobin, Fluazinam, Propineb, Chlorfenapyr and Dinotefuran as written standards for the calibration curve after each sample were analyzed on the qualitative and quantitative. Regions are common in samples in Pyridaphenthion, Chlorothalonil, Azoxystrobin, Propineb, and Dinotefuran were not detected but the two pesticides(Fluazinam and Chlorfenapyr) were detected. ◁표 삽입▷(원문을 참조하세요) When the pesticide is detected as shown in the above table, Chlorfenapyr allowance does not go beyond the limits the Dried chinese matrimony vine hit 2.0ppm, Chlorfenapyr for all classified into five regions goods acceptance and Fluazinam was not detected the remaining four regions of the detected in terms of replacing, to replace the hit is detected the acceptance criteria across the 0.3ppm are classified throw-out.
