ActivityHerbicide.
Amidosulfuron is a systemic herbicide intended for spring control of cleavers (Galium aparine). It is primarily absorbed by the leaves of plants but is also absorbed through the roots. Weeds die within six weeks of treatment. Amidosulfuron may be applied from early post-emergence of the crop until GS 49. Cleavers are controlled from emergence through to budding. The product is active at temperatures as low as 2oC but may only stunt the growth of weeds rather than kill them at these temperatures. The application rate in cereals may be reduced if amidosulfuron is tank-mixed with other broadleaf herbicides. The company recommends only one application per season.
In field trials, amidosulfuron has been shown to be safe on crops grown in rotation with cereals, including oilseed rape, sugar beet and sunflowers, which are sensitive to the product. -

Fate in :
Fate in soil:
Amidosulfuron is degraded by microbes in the soil; the half-life is less than 30 days. Degradation in soil is unaffected by soil type and pH. It has low soil mobility. Fate in aquatic systems:
Amidosulfuron has a half-life of 29-120 days in natural systems. Degradation is faster in systems with high organic content.
