DESCRIPTION
|
It affects sensitive weeds through inhibition of the enzyme acetolactate synthase (ALS). Inhibition of ALS leads to the rapid cessation of the cell division and subsequent growth processes in plants
|
Mode of action
|
Selective systemic herbicide absorbed through the roots and foliage and translocated the apex of the plants. Symptoms appear within days, with death within 2-4 weeks.
|
Applications
it is a selective systemic post emergence herbicide.
Rapid cessation of cell division and subsequent growth.
It controls a wide range of grass weeds and broad leaf weeds.
It is safe for neighbouring broad leaved and other crops.

WHO (a.i.) U; Unlikely to present acute hazard
|
Environmental Toxicity
|
:
|
The methoxy carbonyl and sulfonylurea groups are only partly degraded by O-demethylation and hydroxylation. It undergoes complete degradation with in few days, by hydrolysis and conjugation in plants. It is non toxic for bobwhite quail and mallard ducks. It is non toxic for Bluegill sunfish, Rainbow Trout, Channel Catfish. It is non toxic for daphnia. It is non toxic for honeybees. It is non toxic for worms.
