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.

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.

The adsorption behavior and mechanism of eight sulfonylurea herbicides on humic acid (HA) was studied with the method of batch equilibrium and the technique of Fourier transform infrared (FT-IR) was used to observe its sorption mechanism.

This article summarized the mode of action,selectivity and environmental behaviors of sulfonylurea herbicides,and discussed the most important problems,such as herbicide resistance and residual analytical methods,encountered during its development and application,and indicated the direction of its development and the strategies of solving the problems.

The effect of the three sulfonylurea herbicides, iodosulfuron, chlorsulfuron, and bensulfuron, on growth of Anabaena algal blooms was determined by visible spectrophotometry.
