Herbicide Nicosulfuron

2022-01-20

Nicosulfuron is an organic compound with the molecular formula C15H18N6O6S, which belongs to the sulfonylurea class of selective herbicides and is usually used as a post-emergence herbicide to protect corn crops from weeds.

Name: nicosulfuron
Chemical formula: C15H18N6O6S
Molecular weight: 410.41
CAS number: 111991-09-4
Density: 1.5 g/cm³
Appearance: white solid

Nicosulfuron is a systemic herbicide, which can be absorbed by the stems, leaves and roots of weeds, and then conducted in plants, causing growth stagnation of sensitive plants, chlorosis of stems and leaves, and gradual death. Generally, it will die within 20-25 days. However, some perennial weeds will take longer at cooler temperatures. The effect of applying the medicine before the 4-leaf stage after budding is good, and the effect of applying the medicine decreases when the seedlings are large. The drug has pre-emergent herbicidal activity, but the activity is lower than post-emergence.

Prevention object
It can control annual and perennial grass weeds and some broadleaf weeds. Tests have shown that the weeds with strong sensitivity to the drug include barnyardgrass, foxtail, wild oat, and amaranth; the weeds with moderate sensitivity include Polygonum benthamiana, Liga, purslane, duck tongue, cocklebur and abalone Hemp, sedge; weeds with poor sensitivity are mainly quinoa, nightshade, duck toe, kochia and weasel.

Applicable crops: corn.
