Results and discussion

Any other information on results incl. tables

Propanil (N-(3,4-dichlorophenyl)-propanamide)

3,4-DCA is also a metabolite of the herbicide propanil. After the application of 6.8 kg propanil/ha (which is an excessive application, the authors state an amount of 3.4 kg/ha to be normal), 3,4-DCA was measured in the top soil layer after the field was flooded. Concentrations of 29 mg/kg after 3 days, 8 mg/kg after 7 and 6 mg/kg after 14 days were detected, after this times only traces of propanil were present.
