N2  - The grain yield responses of cultivars of canola, field pea, lupin and faba bean to the recommended rates and twice the recommended rates of pre- and post-emergence herbicides were examined in field trials conducted at Wagga Wagga, New South Wales, from 1986 to 1989. Significant (P<0.05) reductions in grain yield of some field pea cultivars resulted from the recommended rate of registered post-emergence herbicides: Cressy Blue (22%), Derrimut (20%) and Dundale (13%) with metribuzin (0.23 kg a.i./ha); Wirrega (26%) with cyanazine (1.0 kg a.i./ha); Wirrega (15%) and Maitland (13%) with methabenzthiazuron (0.6 kg a.i./ha). The canola lines Hyola 30 and BLC 198-82 also had significant reductions in yield (16-19%) from the recommended rate of clopyralid (0.09 kg a.i./ha). There were differences in cultivar (or advanced line) tolerance to other herbicides at twice the recommended rate: clopyralid (0.18 kg a.i./ha) applied post-emergence in canola; diflufenican (0.2 kg a.i./ha) and MCPA (0.75 kg a.i./ha) applied post-emergence in field pea; preemergence treatments of metribuzin (0.46 kg a.i./ha), cyanazine (3.0 kg a.i./ha) and simazine (3.0 kg a,i./ha), and post-emergence treatments of simazine (2.0 kg a.i./ha) and diflufenican (0.2 kg a.i./ha), in lupin. Faba bean cv. Fiord tolerated pre-emergence treatments of terbutryne (2.0 kg a.i./ha), prometryne (3.0 kg a.i./ha) and triallate (1.6 kg a.i./ha), and there was seasonal variation in faba bean tolerance to pre-emergence treatment with cyanazine (3 kg a.i./ha), metribuzin (0.42 kg a.i./ha) and simazine (2.0 kg a.i./ha). The crops tolerated the early post-emergence grass herbicides: clethodim (0.48 kg a.i./ha), diclofop-methyl (1.5 kg a.i./ha), fluazifop-P (0.21 kg a.i./ha), haloxyfop (0.156 kg a.i./ha), quizalofop (0.28 kg a.i./ha), sethoxydim (0.372 kg a.i./ha). Herbicides that were tested in field pea and found to have only marginal selectivity at the recommended rate (even though some cultivars were tolerant) were terbutryne + MCPA (0.4 + 0.15 kg a.i./ha), diuron (0.4 kg a.i./ha) and pyridate (1.35 kg a.i./ha). Pyridate was non-selective in canola, lupin and faba bean. Faba bean tolerance to glyphosate (0.18 kg a.i./ha) was achieved in 1989 if application was delayed from 11 to 15 weeks after sowing.
