| Product | Nicosulfuron |
| Solubility | Soluble in water. Solubility 4.5g/kg in ethanol. |
| Specification | 95%TC,97%TC,98%TC,75%WG |
| Function | Herbicide |
| Application | The weeds sensitive to the drug were barnyard grass, setaria grass, wild oats and amaranth. The weeds with medium sensitivity were Polygonum bendii, Leucia, portulaca, Hadenoglossus, Xanthium and Abutilon, sedge. The main weeds with poor sensitivity were chenopodium, nightshade, ducktoe, pachyderma and weasel flower. |
Nicosulfuron is an endogenous herbicide, which can be absorbed by the stems, leaves and roots of weeds, and then conducted in the plant body, resulting in growth stagnation of sensitive plants, chlorosis of stems and leaves, and gradual death. In general, death takes 20-25 days, but in the case of low temperature, some perennial weeds need longer time. The efficacy of the drug applied before the 4th leaf stage after bud was good, and the efficacy of the drug applied when the seedling was large was decreased. The drug has herbicidal activity before bud, but the activity is lower than that after bud.
| Peculiarity | Nicosulfuron is an endogenous herbicide, which can be absorbed by the stems, leaves and roots of weeds, and then conducted in the plant body, resulting in growth stagnation of sensitive plants, chlorosis of stems and leaves, and gradual death. In general, death takes 20-25 days, but in the case of low temperature, some perennial weeds need longer time. The efficacy of the drug applied before the 4th leaf stage after bud was good, and the efficacy of the drug applied when the seedling was large was decreased. The drug has herbicidal activity before bud, but the activity is lower than that after bud. 1.this product is a special process of vegetable oil suspension, usually use corn oil or industrial soybean oil as a solvent, not only enhance the weed control effect, while grass can be applied, do not have to wait for rain. 2.the quick effect is good, 5-7 days after the application of weeds began to change color and wilt. 3.good efficacy, this product not only has a very good stem and leaf killing effect, but also has a certain soil sealing effect, 30 days after the drug is still effective against weeds. 4. good rain resistance, 8 hours after the application of rain does not affect the efficacy. 5. good safety, under normal conditions will not cause any adverse effects on corn and subsequent crops. However, excessive use can not be used, and excessive use is easy to reduce the emergence rate of small seeds in the following crops. |
| Control object | It can control annual and perennial grass weeds and some broad-leaved weeds. The results showed that the weeds sensitive to the drug were barnyard grass, setaria grass, wild oats and amaranth. The weeds with medium sensitivity were Polygonum bendii, Leucia, portulaca, Hadenoglossus, Xanthium and Abutilon, sedge. The main weeds with poor sensitivity were chenopodium, nightshade, ducktoe, pachyderma and weasel flower. |
| Attention | After application, the leaves of maize were observed to have slight chlorosis and yellow spots, but they could recover quickly. Maize is more sensitive to drug damage in less than 2 leaf stage and more than 5 leaf stage. Corn susceptible to this drug varieties include sweet corn and burst corn. Maize treated with organophosphorus insecticides is sensitive to this agent. The temperature at the time of application is about 20ºC, the air humidity is above 60%, and there is no rain within 12 hours after application, which is conducive to the play of the drug effect. 1. The sensitivity of different maize varieties to nicosulfuron was different, and the safety sequence was horse tooth type > Hard corn > Burst corn Sweet corn. Generally, maize was sensitive to the drug before 2 leaf stage and after 10 leaf stage. Sweet corn or burst corn is sensitive to the agent, do not use. 2. No residual drug damage to subsequent wheat, garlic, alfalfa, potato, soybean, etc.; But it is harmful to Chinese cabbage, beet, spinach, cucumber, sunflower and oil sunflower. In the area of intercropping or rotation of grain and vegetable, it is necessary to do a good job in the test of drug damage to the later vegetables. 3. When mixed with 2, 4-drops, the liquid should be avoided from drifting to other nearby broad-leaved crops, and the sprayer should be dedicated. 4. Corn treated with organophosphorus is sensitive to the drug. The interval between the use of the two drugs is about 7 days. Nicosulfuron can be mixed with pyrethroid pesticides. 5. It rains 6 hours after application, which has no obvious effect on the efficacy and does not need to be re-sprayed. 6. The maximum residue limit (MRL) in corn is 0.02 mg/kg, the maximum dose per mu is 4 grams (effective ingredient), the maximum number of applications is 1 time, the safety interval is 30 days. 7. Avoid direct sunlight. Keep it separate from seeds, seedlings, fertilizers and other pesticides, and keep it sealed in a low temperature and dry place as far as possible. |
