Nicosulfuron 80% WDG is an endophytic herbicide, which is absorbed by the stems, leaves and roots of weeds, and then transmitted in plants, resulting in growth stagnation, chlorosis of stems and leaves, and gradual death of sensitive plants.
In general, it takes 20-25 days to die, but it takes a long time for some perennial weeds under low temperature.
The results showed that the effect of spraying before the fourth leaf stage after bud was good, but it decreased when the seedling was big. It has the herbicidal activity before bud, but the activity after bud is low.
Annual weeds and some broadleaf weeds can be controlled.
Weeds with high sensitivity to barnyard grass, Setaria, wild oats, amaranth retroflexus, etc.
The weeds with moderate sensitivity to fungicides were Polygonum benderi, Herba Lysimachiae, Portulaca oleracea, Xanthium sibiricum, Herba sedge, etc.
Chenopodium album, Solanum nigrum, Digitaria dactylon, Kochia scoparia, etc.
Suitable crop: corn.
The results showed that the leaves of maize had mild chlorotic macula, but could recover quickly. Maize is sensitive to pesticides when it is below 2-leaf stage and above 5-leaf stage.
The results showed that the temperature was about 20 ℃, the air humidity was above 60%, and there was no rainfall within 12 hours after spraying, which was conducive to the development of the efficacy.
| Crops | Weeds | Dosage | Using method |
| Spring corn field | Annual monocotyledonous and dicotyledonous weeds | 49.5-75 (g/ha) | Spray |
| Summer corn field | Annual monocotyledonous and dicotyledonous weeds | 49.5-63 (g/ha) | Spray |
The sensitivity of maize varieties to Nicosulfuron was different.
Corn treated with organophosphorus insecticides is sensitive to this insecticide.
It rained after 6 hours, which had no obvious effect on the efficacy of the drug, so it was unnecessary to spray it again.
Nicosulfuron 80% WDG can be mixed with pyrethroids.
