Nicosulfuron 95 TC

features :

(1) is a residual sulfonylurea compound used as a selective pre-and postemergennce herbicide

for broadleaf weeds and some annual grassed,

(2) It is a systemic compound with foliar and soil activity , and it works rapidly after it is taken

up by the plant . Its mode of action is by hnhibiting cell dividion in the shoots and roots of

the plant , and it is biologically active at low use rates.

Common Name:	Nicosulfuron
Chemical Name:	2-[(4,6-dimethoxypyrimidin-2-ylcarbamoyl)sulfamoyl]-N,N-dimethylnicotinamide
CAS No.:	111991-09-4
Structure:
Molecular Formula:	C15H18N6O6S
Molecular Weight:	410.4
Physical Chemistry:	Technical can be recognized as white powder or colorless crystals.Water Solubility: @ 25 degrees C: 0.04 g/100g pH=5.0; 1.2 g/100g pH=7.0; 3.9 g/100g pH=9.0.Solubility in Other Solvents: @ 25 degrees C: 0.04 g/100g pH=5.0; 1.2 g/100g pH=7.0; 3.9 g/100g pH=9.0.Melting Point: 141-144 degrees C.Vapor Pressure: 1.2 x 10 to the minus 16 torr at 25 degrees C.
Toxicity:	The acute oral LD50 for technical nicosulfuron was reported to be >5,000 mg/kg body weight. The acute dermal LD50 was >2,000 mg/kg body weight. The acute inhalation LC50 was >5.9 mg/L. Primary dermal irritation testing showed nicosulfuron to be a non-irritant and a non-sensitizer. The primary eye irritation testing showed nicosulfuron to be a moderate irritant.
Application:	Nicosulfuron is a member of the sulfonylurea family of herbicides. It controls weeds by inhibiting the plant enzyme acetolactate synthase, or ALS. This enzyme is not found in livestock, fish or man. Inhibiting the ALS enzyme system blocks the production of the amino acids, valine and isoleucine, essential building blocks of proteins and other plant components.
