Dissipation rates and residues of fungicide azoxystrobin in ginseng and soil at two different cultivated regions in China
The results, particularly the high residues of azoxystrobin observed in ginseng plant parts, provide a quantitative basis for revising the application of this pesticide to ginsen, suggesting that these were affected by local soil characteristics and climate. Expand
Simultaneous Determination of Five Diamide Insecticides in Food Matrices Using Carbon Nanotube Multiplug Filtration Cleanup and Ultra-High-Performance Liquid Chromatography-Tandem Mass Spectrometry.
An analytical method was developed and validated for simultaneous determination of five diamide insecticides chlorantraniliprole, cyantranilanilip Role, flubendiamide, cyclanilip role, and tetrachlorantranILiprole in food matrices and the results indicate this method is reliable for monitoring the five diamides in food.

Biodegradation of Atrazine by the Novel Klebsiella variicola Strain FH-1
Three genes (atzC, trzN, and trzD) encoding for Atrazine degrading enzymes were identified by PCR and sequencing in strain FH-1 and provide additional theoretical support for the application of strain Fh-1 in bioremediation of fields polluted by Atrazines. Expand
Simultaneous Determination of Five Neonicotinoid Insecticides in Edible Fungi Using Ultrahigh-Performance Liquid Chromatography-Tandem Mass Spectrometry (UHPLC-MS/MS)
A robust analytical method for simultaneously determining five neonicotinoid insecticides (clothianidin, dinotefuran, imidacloprid, thiacloprid, and thiamethoxam) in commonly consumed edible fungiExpand
Fungicide azoxystrobin induced changes on the soil microbiome
Abstract Azoxystrobin is a widely used systemic fungicide in the Northeast of China, but it is unclear how azoxystrobin impacts the soil microbiome. Thus, we studied the impact of azoxystrobin on theExpand
Dissipation and residues of the diamide insecticide chlorantraniliprole in ginseng ecosystems under different cultivation environments
Investigation of the dissipation and residues of the diamide insecticide chlorantraniliprole in ginseng ecosystems in these two cultivation environments concluded that CAP application strategies for the control of Lepidoptera pests such as armyworms, and the safety of harvested gINSeng roots are recommended for ginsENG cultivated in forests and non-forest areas based on the results of the CAP residue experiments.

Pesticides Residues Rapid Extraction from Panax Ginseng Using a Modified QuEChERS Method for GC–MS
A modified quick, easy, cheap, effective, rugged and safe (QuEChERS) rapid detection method followed by gas chromatography–tandem mass spectrometry (GC–MS) has been developed for the simultaneousExpand
Photodegradation of new herbicide HW-02 in organic solvents.
By separation and identification of photoproducts using GC-MS, it could be concluded that HW-02 was photolyzed through ester cleavage, photo-dechlorination and photoisomerization of the molecule itself. Expand
Two new fatty acids esters were detected in ginseng stems by the application of azoxystrobin and the increasing of antioxidant enzyme activity and ginsenosides content.
It is suggested that azoxystrobin plays an important role in delaying of senescence by changing physiological and biochemical indicators and increasing ginsenosides content in ginseng stems. Expand
Pesticide Residue Rapid Extraction from Ginseng Tea Using a Modified Luke Method for GC–MS
A modified Luke rapid detection method followed by gas chromatography–mass spectrometry (GC–MS) has been developed for the simultaneous determination of 42 pesticides in ginseng tea. This method usesExpand
