Other claims from this paper (8)
- Observation Myosotis arvensis was the dominant weed species, at up to 48,000 plants per hectare.
- Observation Myosotis arvensis contributed the highest field-level pyrrolizidine alkaloid load, up to 669.3 mg per hectare.
- Observation Anchusa arvensis occurred at lower densities, up to 2400 plants per hectare.
- Observation Anchusa arvensis had a total PA load of 104.8 mg per hectare.
- Observation In Myosotis arvensis, pyrrolizidine alkaloid concentrations increased toward the upper plant segments.
- Observation No pyrrolizidine alkaloids were detected (below the limit of quantification) in chamomile samples collected within 10 cm of PA-producing weeds.
- Mechanism Contamination hazard at harvest was determined by the amount of PA-bearing biomass in the harvest-relevant zone.
- Mechanism Under the investigated conditions, chamomile contamination hazard was primarily associated with mechanical admixture during harvest rather than soil-mediated transfer.
