Summary
Sulfonylureas are a family of environmentally compatible herbicides that were discovered by DuPont Crop Protection in 1975 and first commercialized for wheat and barley crops in 1982. They have now been developed and commercialized worldwide in all major agronomic crops and for many specialty uses (e.g., rangeland/pasture, forestry, vegetation management).
Sulfonylureas represent a major advance in global crop protection technology and have revolutionized weed control by introducing a unique mode of action. Specifically, these compounds interfere with a key enzyme required for weed cell growth — acetolactate synthase. Furthermore, sulfonylureas are compatible with the global trend toward post emergence weed control and integrated ...

Interview
Jiangsu Institute of Ecomones Co., Ltd (JIE) is a leading sulfonyurea(SU) herbicides in China. Mr. Kong Fanlei, President of JIE, shared with Agropages his insight of the SU herbicides industry. Though the rapid adoption of GMO crops is impacting traditional agrochemical industry considerably, Mr. Kong believed that chemical pesticides such as SU products are having a promising prospect for their efficiency and safeness.
JIE dominated its role in China by its various kinds of SU products and R&D abilities from intermediates, technicals to formulations, as well as standard-setting in this field. As more and more concerns on health and environmental problems, JIE has reduced its product line from over 50 to 35, which including bensulfuron, metsulfuron, chlorsulfuron, thifensulfuron, tribenuron, ethametsulfuron-methyl, nicosulfuron, triasulfuron, chlorimuron, rimsulfuron etc....Read more>>
