Environmental fate:
Fate in soil:
In the laboratory, florasulam had a soil half-life of <1 - 4.5 days; in the field it had a soil half-life of 2-18 days. Results published by Dow in the Journal of Agrichemical Food demonstrated that this half life is dependent on temperature and independent of moisture levels. Dow reported the half-life degradation of florasulam in soil to range from 1.0 to 8.5 days at 20 to 25 °C and from 6.4 to 85 days at 5 °C.
Fate in aquatic systems:
In natural systems, florasulam has a half-life of 9-29 days in the dark. The anaerobic aquatic degradation DT50 is 13 days; the aerobic DT50 is 3 days. Photolysis is also an important method of degradation. Florasulam's photolytic half-life is approximately five days.
The EU SCP concluded that two metabolites of florasulam posed no risk to non-target aquatic organisms and would not exceed the European threshold for groundwater contamination.
