- Basis for effect:
- seedling emergence
- Details on results:
- Method of recording the values for growth (units used): The fresh weight of each plant was determined at day 21.
The plants were cut directly above the soil surface weight immediately after cutting.
Signs of toxicity:
Phytotoxicity could not be noticed in the broad leaf species
Brassica oleracea and Glycine max. In avena sativa slight
phytotoxic effects (< 25 %) were observed up to 100 mg/kg.
In the maximum concentration of 1000 mg/kg, the effects
stayed under 50 %.
