Residue Level and Degradation Dynamics of Metalaxyl-M in Tobacco and Soil;

Field trail for metalaxyl-M residue in grape and soil were conducted in suburbs of Beijing and Hangzhou city, respectively.

Metalaxyl-M is a(R)-enantiomer of racemate metalaxyl,and is mostly eluted with n-hexane and diethyl ether mixed eluting solution in analysis of residues in agricultural products by applying acidic alumina(active grade V) chromatographic column.

Separation of Metalaxyl Enantiomers by Capillary Electrophoresis with Conductive Detection;

HPLC determination metalaxyl residues in vegetable;

Chiral Resolution of Metalaxyl Intermediate Enantiomers by HPLCwith Cellulose-based Chiral Stationary Phase;

Eleven metalaxyl-resistant isolates were obtained from sensitive strain of Phytophthora nicotianae var.
