Popis:	This study was conducted to evaluate the efficacy and phytotoxicity of glufosinate-ammonium in controlling annual and perennial weeds on paddy ridges. Glufosinate-ammonium SL (900 g a. i./ha) and glufosinate-ammonium ME (600 g a. i./ha) mixed with fluthiacet-methyl (10 g a. i./ha) were tested in the field experiments. Five annual weed species, Glycine soja, Erigeron canadensis, Disitaria ciliaris, Poa annua and Echinochloa utilis, and four perennial weed species Elymus tsukushensis, Taraxacum platycarpum, Equisetum arvense and Artemisia princeps were identified on the paddy ridges. The results of this experiment indicated that these annual and perennial weeds could be effectively controlled by both the herbicides. Application of these herbicides did not negatively affect the number of tillers and plant height of rice grown near the treated paddy ridges. Therefore, it can be concluded that the non-selective glufosinate-ammonium can provide an effective control of weeds on the paddy ridges if application is properly made.
