Common Name: Nicosulfuron
CAS No.: 111991-09-4
Synonyms: 2-[[(4,6-DIMETHOXYPYRIMIDIN-2-YL) AMINO-CARBONYL]AMINO SULFONYL]-N,N-DIMETHYL-3-PYRIDINE CARBOXAMIDE;2-[(4,6-dimethoxypyrimidin-2-ylcarbamoyl)sulfamoyl]-n,n-dimethylnicotinamide;1-(4,6-dimethoxypyrimidin-2-yl)-3-(3-dimethylcarbamoyl-2-pyridylsulfonyl)urea;ACCENT;ACCENT (TM);DASUL;NICOSULFURON;NICOSULFURONOXAMIDE
Molecular Formula: C15H18N6O6S
Agrochemical Type: Herbicide
Mode of Action: Selective post-emergence herbicide, used to control annual grass weeds, broad‑leaved weeds and perennials grass weeds such as Sorghum halepense and Agropyron repens in maize. Nicosulfuron is rapidly absorbed into the weed leaves and is translocated through the xylem and phloem towards the meristematic zone. In this zone, Nicosulfuron inhibits acetolactate synthase (ALS), a key enzyme for branched‑chain aminoacids synthesis, which results in cessation of cell division and plant growth.
Formulation: Nicosulfuron 40g/L OD, 75% WDG, 6%OD, 4%SC, 10%WP, 95% TC

Nicosulfuron is a kind of herbicides belonging to the sulfonylurea family. It is a broad-spectrum herbicide that can controls many kinds of maize weeds including both annual weeds and perennial weed including Johnsongrass, quackgrass, foxtails, shattercane, panicums, barnyardgrass, sandbur, pigweed and morningglory. It is a systemic selective herbicide, being effective in killing plants near the maize. This selectivity is achieved through maize’s capability of metabolizing Nicosulfuron into harmless compound. Its mechanism of action is through inhibiting the enzyme acetolactate synthase (ALS) of the weeds, blocking the synthesis of amino acids such as valine and isoleucine, and finally inhibiting the protein synthesis and causing death of weeds.
Selective post-emergence control in maize of annual grass weeds, broad-leaved weeds.
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.
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.
The corn treated with the organophosphorus agent is sensitive to the drug, and the safe use interval of the two agents is 7 days.
It rained after 6 hours of application, and had no obvious effect on the efficacy. It was not necessary to re-spray.
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.
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.
