Applicant's summary and conclusion
- Conclusions:
- Reliability: high quality NOEC values is 40 mg/kg (yield)
No bioavailability correction possible as CEC is not given or can not be derived. - Executive summary:
Effect of different levels of copper (0, 5, 10, 20, 40, 80, 160, 320 and 640 mg/kg soil) was studied on `WL 1562` wheat (Triticum aestivumL. emend. Fiori & Paol.) grown on a Fatehpur loamy sand soil under greenhouse conditions. Mean dry-matter yield of wheat decreased significantly with the application of Cu @ > 20mg/kg soil. Copper- toxicity symptoms in plants were observed with 40 mg Cu/kg soil treatment, and they became severe at its higher levels. Copper content > 15.5µg/g in flage-leaf of wheat and 8 mg/kg in soils indicated the threshold values above which plants would suffer from its toxicity. A significant decline was observed in iron boron content of flag leaf with increase in Cu rate.
