摘要
The 14 C-labelled insecticide, 2,3-dihydro-2,2-dimethyl-7-benzofuranyl methylcarbamate (carbofuran), supplied to the roots of barley ( Hordeum vulgare L. ‘Larker’) and corn ( Zea mays L. ‘Mich 400’) seedlings was readily taken up and transported to the shoots. Alachlor [2-chloro-2′,6′-diethyl- N -(methoxymethyl)acetanilide] did not inhibit carbofuran metabolism in barley or corn. Butylate ( S -ethyl diisobutylthiocarbamate) slightly inhibited carbofuran metabolism in corn roots. Chlorbromuron [3-(4-bromo-3-chlorophenyl)-1-methoxy-1-methylurea] inhibited carbofuran metabolism by decreasing the concentration of 14 C found in the acetone-insoluble residue and the methanol-soluble fraction in barley shoots. Chlorbromuron increased the carbofuran content and decreased the 2,3-dihydro-3-hydroxy-2,2-dimethyl-7-benzofuranyl methylcarbamate (3-hydroxycarbofuran) content of the chloroform-soluble fraction in both barley shoots and roots. Chlorbromuron did not affect carbofuran metabolism in corn.
