Abstract/Contents:"From 2000 to 2003, 27 trials were conducted to evaluate Italian ryegrass control in winter wheat with mesosulfuron-methyl in several formulations. Italian ryegrass density is high in western Oregon because it is grown as a seed crop in rotation with winter wheat. Italian ryegrass resistance to ACCase inhibitors is widespread and resistance to some ALS inhibitors (chlorsulfuron and metsulfuron) has been confirmed. Field trials were conducted at Hyslop Research Farm with susceptible Italian ryegrass and in grower's fields with herbicide-resistant Italian ryegrass. Italian ryegrass control with mesosulfuron was variable. In a trial in 2001 with mesosulfuron / iodosulfuron (0.0134 lb ai/A) applied on five dates across two planting dates, Italian ryegrass control was greater than 90% in all treatments where it had all emerged at the time of application. In 2002, Italian ryegrass control was poor to fair and variable across growth stages when mesosulfuron was applied alone (0.011 lb ai/A) at three Italian ryegrass growth stages. In a trial in 2002, Italian ryegrass control and winter wheat yield were greater with mesosulfuron / iodosulfuron at 0.011 lb ai/A than with mesosulfuron alone at three rates. In 2003, Italian ryegrass control was similar to results in 2002 where mesosulfuron was applied with and without iodosulfuron. However, in general, Italian ryegrass control in 2003 with mesosulfuron alone was better than in 2002. Iodosulfuron is a broadleaf herbicide, but these results suggest that there was a synergistic effect on Italian ryegrass control with the mesosulfuron / iodosulfuron combination."
