Applicant's summary and conclusion
- Executive summary:
The development of roots and leafs on rice, turnip and soybean was examined on an agar solution, and compared to the growth in the controls. For rice a 5-day NOEC of 10 mg/l was determined, and for turnip a 4-day NOEC of 10 mg/l was received. On soybean a growth of 72 % was obtained for root length, and 82 % growth for leaf length within 4 days at a test concentration of 1 mg/l.
