Abstract

The uptake of naptalam (N-1-naphthylphthalamic acid) by wheat (Triticum vulgare L. ‘Mericopa’) and soybean (Glycine max (L.) Merr. ‘York’) was enhanced when the herbicide was applied simultaneously with SADH (succinic acid-2,2-dimethylhydrazide). Both root and shoot systems of growth regulator-treated plants exhibited enhanced herbicide uptake. Naptalam uptake by wheat seedlings was also stimulated by GA (gibberellic acid), but the GA influence in this respect was less dramatic than that of SADH. The uptake of the herbicide by soybean was not influenced by GA.
