SDS-3701 K oc 95, 190, 98% r.a. remained
in top 5 cm.
After 7-60 days aging followed by
2-45 days leaching, r.a. was
leached in amounts up to 30% of
applied. In case r.a. was
identified, chlorothalonil, SDS-
3701, SDS-19221 and SDS-
46851 were present, the latter in
higher amounts than found after
ageing. However, in the study
with the highest amounts of
identified compounds, the water
flux was too high. In several
