Abstract

Effect of transgenic rice with glufosinate-resistance on weed populations in paddy field.

Abstract

An experiment was conducted during 2001 and 2003 in China, to determine the effect of transgenic rice cultivars 99-1 and Jiahe 201 on weed population in rice fields. Glufosinate (304, 385 and 506 g/hm2), a special herbicide for glufosinate-resistant transgenic rice, efficiently controlled Leptochloa chinensis, Rotala indica, Lindernia procumbens, Ludwigia prostrata, Eclipta prostrata, Paspalum distichum, Marsilea quadrifolia and Murdannia triquetra. However, it did not control Eleusine indica, Eleocharis acicularis, Eleocharis plantagineiformis and Alternanthera philoxeroides. Both 99-1 and Jiahe 201 did not have any allelopathic effects.
