The preparation method of the water dispersible granules of 80% nicosulfuron was introduced.

With the starting material of 2-chloropyridine-3-carboxylic acid, nicosulfuron was synthesized by seven steps including amidization, esterification, condensation and so on.

This paper reported the weed control efficiency ofnicosulfuron and its mixture With other herbicides in maizefields of the North of Jiangsu province.

Synthesis of the intermediate of herbicide nicosulfuron 2-aminosulfonyl-N,N-dimethylnicotinamide;

Desorption character of nicosulfuron and effect of pH on adsoroption of nicosulfuron in soils;

Research of synergism of adjuvant Quad7 on nicosulfuron;

This paper study the synthetic route of fluoropyrimidinesulfuron, fluoropyrimidinesulfuron was synthesized from nitrateguanidine, diety1 malonate and sugar as starting reagent, which was subjected to five-step reaction, and with a total yield of.

In this paper a high performance liquid chromatographic method for the separation and determination of metsulfuron, bensulfuron and acetochlor in the composite herbicide “Nongjiayi” is described.

The results of field trials showed that 18% Daocaoling WP(mixture of acetochlor, bensulfuron and metsulfuronmethyl)at 225￣825g/ha against weeds in paddy gave good control effect for 92.

This paper was mainly concerned about the determination of bensulfuron-methyl content in Dingxinong granule which were butachlor, simetryn and bensulfuron-methyl mixture.

The results of this expriment show that the joint action of the mixture of napropamide and acetochlor and bensulfuron-methyl is addition.
