A study of 14 urea herbicides showed a high correlation (R=0871 2, S=0188) between their octanolwater partition coefficients and molecular connectivity indexes, making possible the prediction of the partition behavior of untested urea herbicides on the basis of their connectivity.

Theoretical study on hydrolysis mechanism of three typical sulfonylurea herbicides;

Effect of sulfonylurea herbicides on biological indicators characterizing the soil quality;

A low level multi sulfonylurea herbicides residue analytical method based on extraction enrichment combined with capillary electrophoresis was studied.

But some environmental issues caused by sulfonylurea herbicides, such as Chlorimuron and Chlorsulfuron, are urgently settled because of their too long residual period and the fast growth of the weeds.

It is a great challenge to detect and analyze 1ppb or lower residue level of sulfonylurea herbicides in the environmental matrices such as soils,water,and animal and plant tissues.

for they are influenced by some sorts of sulfonylurea herbicides including monosulfuron-ester.

Estimation of the aqueous solubilities of phenylurea herbicides;

Used widely and high toxicity make it necessary to monitor the concentration of phenylurea herbicides in the environment.

Validation of the method of HPTLC on detecting five sulfonylureas;

28 nm resolution crystal structure of yeast acetolactate synthase in complex with a sulfonylurea herbicide,chlorimuron ethyl and the 3D structure of Arabidopsis thaliana acetolactate synthase in complex with sulfonylureas and imidazolinone herbicides were reviewed.
