| ABSTRACT Weeds are among the main constraints to high grain yield on hexaploid oat (Avena sativa), but there are few herbicides registered for weed control on this cereal crop. The objectives of this study were to evaluate the impact of the iodosulfuron-methyl on grain yield of elite oat cultivars and investigate the mechanism of oat tolerance to this herbicide. A field experiment conducted in 2012 demonstrated there was no difference on grain yield between cultivars URS Guará and URS Guria, when iodosulfuron-methyl was used up to 4.5 g ha-1. Likewise, experiments from 2013 have demonstrated that iodosulfuron-methyl, at 5 g ha-1, did not affect the oat grain yield of the genotype UFRGS 14, but affected it on the cultivars URS Guará and URS Guria. In 2014,... |
