The test was finished 2 weeks after five of the control seedlings have emerged in the control. Lycopersicon esculentum and Raphanus sativus were more sensitive with a NOEC of 300 mg/kg soil dw compared to Avena sativa with a NOEC of 1000 mg/kg soil dw.

Description of key information

NOEC of 300 mg/kg soil dw.

Key value for chemical safety assessment

Short-term EC50 or LC50 for terrestrial plants:
300 mg/kg soil dw
