Estimated degradation half-lives (DT50) for picoxystrobin and 4-n-nonylphenol in a sandy loam soil.

a

Initial phase 0–28 days, 2nd phase 28–70 days,

b

Initial phase 0–14 days, 2nd phase 14–70 days.

Calculations are based on results from both single chemical and mixture experiments. (The test statistic of p<0.05 is valid for all estimated DT50-values.).
