Specs:TC,WDG,SC,WP
Price:00.0 USD Metric Tons
Common name nicosulfuron
IUPAC name 2-(4, 6-
dimethoxypyrimidin-2-
ylcarbamoylsulfamoyl)-N, N-
dimethylnicotinamide

APPLICATIONS

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.

Uses 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.
