Dynamics of Carbendazim Residue in Panax notoginseng and Soil

To provide scientific information for GAP of P. notoginseng and guiding the farmers and enterprises of Chinese medicine, dynamics of carbendazim residue in the Chinese medicinal herb, P. notoginseng and cultivated soil was studied at Wenshan County in 2008. The half lives of carbendazim in P. notoginseng were 5.92-6.82 day (soil), 6.71-6.77 day (fresh leaf), 3.29-3.93 day (fresh root), and 31.50-36.67 day (powder of the dry root) separately. Carbendazim residues in P. notoginseng were more stable during storage stage than growing stage.
