Description of key information
Additional information
Soil
Fenpropimorph is completely biodegradable in soil under aerobic conditions. It shows a significant mineralisation rate with up to 18% TAR after 45 days of incubation. The formation of bound residues reaches 44% TAR after 360 days. As a first step in degradation, the molecule undergoes oxidation at various carbon atoms in the molecule. Under aerobic conditions in the dark the degradates fenpropimorph-acid (BF 421-2) and BF 421-7 are the first appearing compounds, whereas under the influence of light BF 421-13 and BF 421-15 were formed. Under anaerobic conditions the degradation of fenpropimorph is slow with low amounts of C02 and bound residues.
Fenpropimorph is degraded in soil under laboratory conditions with an average DT50 value of 19.6 days under aerobic conditions at 20°C. Photolysis does not change the rate significantly.
The DT50 values under outdoor field conditions were ranging from 10 to 90 days. Within some of the degradation studies, a somewhat slower degradation of fenpropimorph occurred after an initial fast decrease in concentration.
Water
Fenpropimorph is hydrolytically stable in the pH-range from 3 to 9. It is also photolytically stable. Nevertheless, it is degraded in the water/sediment study in the dark. Mineralisation of 6 to 8% TAR occurred within 100 days. The DT50 values for the total systems were 54 and 18 days, forming an arithmetical mean of 36 days at 20°C. The high adsorption coefficient leads to a fast movement into the sediment. Within the sediment, Fenpropimorph is oxidised to the metabolite fenpropimorph-acid, which is due to its weaker adsorption and better solubility released from the sediment and found in higher concentrations in the water phase.
After 100 days of incubation, fenpropimorph-acid was detected in the water phases up to 7% TAR and in the sediment up to 23% TAR. The DT50 values in the 2 water phases were 39 and 121 days (arithm. mean = 80, at 20°C).
These results show that in case Fenpropimorph reaches the water, it quickly disappears from the water phase by adsorption and is then converted to fenpropimorph-acid by oxidation. fenpropimorph-acid is a major metabolite in water.
Air
When reaching the troposphere, Fenpropimorph is degraded very fast by photochemical processes with a half life of 2.9 h.
