Selectivity and absorption of the herbicide naproanilide in rice plants (Oryza sativa L.) and Sagittaria pygmaea Miq

The selectivity of naproanilide [2-(2-naphthoxy)propionanilide] in rice plants, broadleaf and cyperaceous weeds was studied through both pre- and post-emergence tests. Rice plants were found extensively tolerant to naproanilide, while Cyperus difformis L, , Monochoria vaginalis BURM, f., Rotala indi...

Summary:The selectivity of naproanilide [2-(2-naphthoxy)propionanilide] in rice plants, broadleaf and cyperaceous weeds was studied through both pre- and post-emergence tests. Rice plants were found extensively tolerant to naproanilide, while Cyperus difformis L, , Monochoria vaginalis BURM, f., Rotala indica WILLD., Sagittaria pygmaea MIQ. and Scirpus juncoides ROXB. were very sensitive. The absorption rate of 14C-naproanilide in rice plants was much lower than in Sag. pygmaea. Moreover, in rice plants the translocation from root to upper portion was retarded, but in Sag. pygmaea, radioactivity was distributed uniformly in the shoot, tuber and root.
