Sinobio Pesticide Herbicide Nicosulfuron 95%TC CAS 111991-09-4

CAS No. 111991-09-4

Purity: >95%
Storage conditions: Keep in dark place,Inert atmosphere,Room temperature
Appearance: White powder

Nicosulfuron methyl is an endogenous herbicide that can be absorbed and rapidly transmitted by the stems, leaves, and roots of plants. By inhibiting the activity of acetyllactate synthase in the plant body, it prevents the synthesis of branched chain amino acids such as histidine, leucine, and isoleucine, thereby preventing cell division and stopping the growth of sensitive plants. The symptoms of weed damage include yellowing, chlorosis, and whitening of the heart leaves, followed by yellowing of other leaves from top to bottom. Generally, symptoms of weed damage can be seen 3-4 days after application, with annual weeds dying within 1-3 weeks, and perennial broad-leaved weeds with less than 6 leaves being suppressed and stopped growing, losing their competitiveness with corn. High doses can also cause the death of perennial weeds.

Usage: At the 3-4 leaf stage of corn, the weeds are uniform and the plant height is about 5cm, and the stems and leaves are sprayed. Use 4% suspending agent 50-75ml/acre (summer corn), 65-100ml/acre (northern spring corn), and spray with 30kg/acre of water.

Herbicide raw materials for agriculture.

Sulfonylurea herbicides inhibit plant acetyllactate synthase (inhibitors of branched chain amino acid synthesis). It can be used to control annual and perennial grasses, sedges, and certain broad-leaved weeds in corn fields. Its activity against narrow leaved weeds exceeds that of broad-leaved weeds, making it safe for corn crops. The recommended dosage is 40g/hm2.

Prevention and control targets

Echinochloa crus, Matang, Ox tendon grass, Dogtail grass, Reverse branch amaranth, Purslane, Abutilon, Convolvulus officinalis, Cirsinia cordata, Cicory coriander, Golden Dogtail grass, Wild millet, Longkui, Elsholtzia splendens, Annual weeds and perennial broad-leaved weeds such as Xanthium sibiricum, Duckweed, Windflower, Cauliflower, Quercus, Artemisia, Thistle, Wild Oat, etc.

Main Features:

1. This product is a vegetable oil suspending agent processed by a special process. Usually, corn oil or industrial-grade soybean oil is used as a solvent, which not only enhances the control effect of weeds but also can be applied when the grass is seen, without waiting for rain.

2. The quick-acting effect is good, and the weeds begin to change color and wither 5-7 days after application.

3. Good lasting effect, this product not only has a very good herbicidal effect on stems and leaves, but also has a certain soil sealing effect, and still has a control effect on weeds 30 days after application.

4. Good rain resistance, rainfall 8 hours after application will not affect the efficacy.

5. It is safe and will not cause any adverse effects on corn and subsequent crops under normal conditions. However, it should not be used in excess. Excessive use will easily reduce the emergence rate of small seeds in the following stubble.


1. Avoid contact with the skin and eyes, and wash hands and face in time after application.
2. The remaining liquid medicine and empty containers after spraying should be properly disposed of. They can be burned or buried deep, and should not be used for other purposes.
3. It should be stored in a ventilated and dry warehouse to prevent moisture and sunlight, and should not be mixed with food, seeds and feed.
4. Pregnant and lactating women should avoid contact.

Matters Needing Attention

1. Different corn varieties have different sensitivities to pesticides, and their safety order is horse toothed>hard corn>burst corn>sweet corn.

Generally, corn is sensitive to this drug before the 2-leaf stage and after the 10 leaf stage. 

Sweet corn or burst corn are sensitive to this agent in fields and inbred lines, and should not be used.

2. There is no residual pesticide damage to subsequent crops such as wheat, garlic, sunflowers, alfalfa, potatoes, soybeans, etc. 

In areas where crops and vegetables are intercropped or rotated, pesticide damage tests should be carried out on subsequent crops of vegetables.

3. Corn treated with organic phosphorus pesticides is sensitive to this drug, and the safe interval between the two pesticides is 7 days. 

After 6 hours of application, it will rain and have no significant impact on the efficacy of the medicine, so there is no need to spray again.

5. Avoid direct sunlight and high temperatures when taking medication. Medication should be effective before 10am and after 4pm. 

6. Separate from seeds, seedlings, fertilizers, and other pesticides, and try to place them in a low temperature, dry place for sealed storage.
