Environmental fate:
Flazasulfuron does not present a risk of bioaccumulation in organisms. There is no negative effect towards soil microorganisms (respiration, nitrification).
Fate in soil:
The half-life of flazasulfuron in soil is 13-16 days. The principal route of degradation in the soil is chemical hydrolysis though there is some contribution from microbial processes. Photolysis does not play a significant role in the decomposition of flazasulfuron.
Flazasulfuron is not strongly adsorbed to soils (the mean Koc in field soil studies is 46). However, the short soil persistence, coupled with the low application rate, acts to minimise the risk of groundwater and surface water contamination.
