Field experiments were conducted in 1982 and 1983 at Invergowrie, Scotland, to examine the selectivity of three post emergence graminicides in faba bean cultivars Medes and Maris Bead grown in weed-free plots in spring. Alloxydim-sodium, sethoxydim, and fluazifop-butyl were applied at recommended rates (1.5, 0.87, and 0.75 kg a.i./ha respectively), and twice that rate. Only alloxydim-sodium at twice the recommended rate (i.e., 3.0 kg a.i./ha) caused some discoloration and marginal necrosis of faba bean leaves, but even this did not affect plant height and yield. Thus, all three graminicides were well tolerated by the faba bean cultivars used in this study
