Common name: Nicosulfuron（CAS NO: 111991-09-4）
   
IUPAC name: 2-(4,6-dimethoxypyrimidin-2-ylcarbamoylsulfamoyl)-N,N-dimethylnicotinamide; 1-(4,6-dimethoxypyrimidin-2-yl)-3-(3-dimethylcarbamoyl-2-pyridylsulfonyl)urea 

Chemical Abstracts name: 2-[[[[(4,6-dimethoxy-2-pyrimidinyl)amino]carbonyl]amino]sulfonyl]-N,N-dimethyl-3-pyridinecarbox amide 

CAS no: 111991-09-4

Mode of action: 
Selective systemic herbicide, absorbed by the foliage and roots, with rapid translocation in xylem and phloem to the meristematic tissues. 

Nicosulfuron is a systemic herbicide that can be absorbed and rapidly transmitted by the stems and roots of plants. It inhibits the activity of acetolactate synthase in plants and prevents the branched chain amino acids, leucine and leucine. The synthesis of the acid further prevents cell division and stops the growth of sensitive plants. The symptoms of weed damage are yellowing, chlorosis and whitening of the heart, and then the other leaves turn yellow from top to bottom. Generally, the weed damage symptoms can be seen 3 to 4 days after application. The annual weeds die within 1 to 3 weeks, and the perennial broadleaf weeds below 6 leaves are inhibited, stop growing, and lose the competitive ability with corn. High doses can also kill perennial weeds.

Application:  
Selective post-emergence control in maize of annual grass weeds, broad-leaved weeds. 

1. Different corn varieties have different sensitivities to the medicinal agents. The order of safety is dentate type > hard corn > popcorn > sweet corn. Generally, the corn is sensitive to the drug before the 2 leaf stage and after the 10th stage. Sweet corn or popcorn seeding, inbred lines are sensitive to this agent, do not use.
2. No residual phytotoxicity to wheat, garlic, sunflower, alfalfa, potato, soybean, etc. In the area of grain and vegetable intercropping or rotation, the phytotoxicity test of post-salty vegetables should be done.
3. The corn treated with the organophosphorus agent is sensitive to the drug, and the safe use interval of the two agents is 7 days.
4. It rained after 6 hours of application, and had no obvious effect on the efficacy. It was not necessary to re-spray.
5. Avoid direct sunlight and avoid high-temperature medication. The effect of medication after 4 o'clock in the morning before 10 o'clock in the morning is good.
6. Separate from seeds, seedlings, fertilizers and other pesticides, and store them in a low-temperature, dry place.

Weeds used to control annual single and double leaves in corn fields.Also can be used in rice fields, Honda and live fields to control annual and perennial broadleaf weeds and sedge weeds, and it also has a certain inhibitory effect on alfalfa.
