Soil bound residues of carbaryl and 1‐naphthol: Release and mineralization in soil, and uptake by plants

Abstract

¹⁴C‐carbaryl and ¹⁴C‐1‐naphthol form soil bound residues which get partially released when barley was grown. ¹⁴C‐residues could be detected in both shoot and root in the case of carbaryl treatment while only roots showed ¹⁴C‐residues in the case of 1‐naphthol. Flooding enhanced release of the bound residues while soil amendment did not. There was greater mineralization of bound residues of carbaryl than that of 1‐naphthol. Rice straw amendment enhanced mineralization.

Key words:

• Carbaryl
• 1‐naphthol
• soil bound residues
• uptake by plants
• soil amendments
• release and mineralization
