| Overview | A new sulfonylurea herbicide developed in 2001, which is used to control most of the broad-leaved weeds and part of the tree family weeds in cotton and sugarcane fields, and has special effects on the weeds of Cyperaceae and aconite. After application, it can be absorbed by the roots, stems and leaves of weeds, and can be conducted downward and upward in the plant body. After the plant is damaged, the growth point is necrotic, the leaf vein is green, and the plant growth is severely inhibited, eventually, the whole plant died. The drug and other sulfonylurea herbicides have the same mechanism of action, by inhibiting the activity of plant acetolactate synthase (ALS), thereby affecting the biosynthesis of branched chain amino acids and play a herbicidal effect. Trifluorosulfuron entered the Brazilian pesticide market in 2001, registered in Latin America, Colombia and Australia in 2002, registered in the United States and Japan in 2003, and Syngenta company expanded to be registered on the lawn in the United States in 2012. Sales reached $0.07 billion in. At present, the herbicides used to control broad-leaved weeds in cotton fields in China are mainly dimeglene, trifluralin, chlorphenazine and other soil treatment agents.|
| properties | the appearance of this product is white crystal. Specific gravity (20 °c, pure product) 1.63g/cm3, Melting Point: 195 °c. The pure product begins to thermally decompose immediately after melting, vapor pressure:(25 ℃, pure product) 500g/L, n-hexane |
| synthetic route | from 2-amino -4, 6-dimethoxypyrimidine and methyl chloroformate reaction 4, methyl 6-dimethoxypyrimidine-2-ylcarbamate is reacted with 3-trifluoroethoxypyridin-2-ylsulfonamide to obtain trifluorosulfuron. 1 is a graph of trifluoroethoxypyridine-2-ylsulfonamide obtained by reacting 3-trifluoroethoxypyridine-2-ylsulfonamide with ethyl chloroformate. 2-amino -4, 6-dimethoxypyrimidine was obtained by the reaction of malononitrile with methanol and cyanamide, further, it is reacted with ethyl 3-trifluoroethoxypyridine-2-ylsulfonamide formate to obtain trifluorosulfuron.

| safety | rational use of trifluorosulfuron can effectively solve the problem that some broad-leaved weeds in cotton fields and some weeds in Cyperaceae such as Aconite are difficult to control, it is relatively safe for cotton. |
| note | 1. Crops can only be used once per season. Mainly used for sugarcane and cotton weed control, if used for other crops, please first safety test. 3. In cotton field spraying, should try to avoid the cotton heart. 4. The individual varieties of cotton leaves have a slight burn, 1 weeks after the rapid recovery, does not affect the yield. |
| Use | herbicide of systemic use in maize field herbicide in cotton and sugarcane field |
