%X Results are reported from 18 experiments in which pre-emergence herbicides were evaluated in narrow-leafed lupins, (Lupinus angustifolius). At all 11 sites south of Perth (latitudes 32°S to 35°S) there was a significant lupin grain yield response to herbicides (P<0.05). There was a significant yield increase at only one of the seven sites north of Perth (latitudes 28°S to 32°S). Significant yield increases were obtained on at least one occasion with alachlor 1.1, 2.2 kg a.i. ha-1; diuron 0.4, 0.8, 1.3 kg a.i. ha-1; linuron 1:1, 2.2 kg a.i. ha-1; simazine 1.1, 1.7, 2.4 kg a.i. ha-1 and trifluralin 0.5, 1.1 kg a.i. ha-1 (P<0.05). Diuron 0.8 kg a.i. ha-1; linuron 2.2 kg a.i. ha-1 and simazine 1.1, 1.7 kg a.i. ha-1 each resulted in a significant lupin yield reduction on one occasion (P<0.05).
