CAS:111991-09-4 Nicosulfuron 2-(4,6-dimethoxypyrimidin-2-ylcarbamoylsulfamoyl)-N,N-dimethylnicotinamide
Active ingredient |
Nicosulfuron |
||
Chemical name |
2-[[[[(4,6-dimethoxy-2-pyrimidinyl)amino]carbonyl]amino]sulfonyl]-N,N-dimethyl-3-pyridinecarboxamide |
||
Classification |
Herbicide / Agrochemical |
||
Biochemistry |
Branched chain amino acid synthesis (ALS or AHAS) inhibitor. Acts by inhibiting biosynthesis of the essential amino acids valine and isoleucine, hence stopping cell division and plant growth. Maize selectivity derives from selective metabolism (P450-mediated pyrimidine-5-hydroxylation, followed by conjugation with glucose). |
||
Mode of action |
Selective systemic herbicide, absorbed by the foliage and roots, with rapid translocation in xylem and phloem to the meristematic tissues. |
||
Usage |
Selective post-emergence control in maize of annual grass weeds including Setaria, Echinochloa, Digitaria, Panicum, Lolium, and Avena spp., broad-leaved weeds including Amaranthus spp. and Cruciferae, and perennials such as Sorghum halepense and Agropyron repens. Applied at 35-70 g/ha. |
Item Appearance Content of a.i. Water Acidity (as H2SO4) |
