Applicant's summary and conclusion

Validity criteria fulfilled:
yes
Executive summary:

Two species (Zea Mays and Daucus Carota) showed no toxicity with NOEC > 1000 mg/kg soil. Seven other species was tested in a range finding study also with no toxic effects at all. However further studies at ongoing for Beta Vulgaris where the test results were inconclusive mainly due to high variability in control
