The maximum concentrations of these compounds were determined as 166pmol/g dry soil after 2days of incubation, 175pmol/g dry soil after 1day and 1,236pmol/g dry soil after 1day, respectively. Biochanin A and the initially formed products degrade too fast to be responsible for clover soil sickness (DT90<20days), but could be precursors for the responsible compounds. The immediate degradation products from biochanin A are all biologically active and are the prime candidates for a reduction of weed pressure caused by clover.
