Hosted by ICAN, the webinar is targeted at grain growers and advisers throughout Australia and will be presented by Peter Newman, of the Australian Herbicide Resistance Initiative... " the webinar will look at the ecology of wild radish and how to use this information to assist in managing it; its herbicide resistance status; and weed control tactics that have been successfully employed to manage this weed.".. To participate, use a laptop, tablet or personal computer to watch and listen to a 30 minute presentation, which will be followed by about 15 minutes for questions...

Project No.: DAW 672 Paper reviewed by: David Minkey and Abul Hashem Crop Updates is a partnership between the Department of Agriculture, Western Australia and the Grains Research & Development Corporation 20.. The negative impact of Raptor and Spinnaker on herbage production observed in the 4 advanced breeding lines (Crop Updates 2004) was not reflected as lower seed set... Overall, 2,4-D and Gramoxone were the most damaging to legume seed production; this reflected the impact of these treatments on herbage production (Crop Updates 2004)...

Australian growers consistently identify herbicide resistance as a major constraint to cropping... We propose that the resistance is primarily due to sequestration of paraquat, limiting paraquat translocation within the plants... Following the recent completion of the 3-year GRDC postdoctoral fellowship, I have been employed by WAHRI as a Research Fellow to continue working on herbicide resistance at the biochemical and molecular levels...

Researchers with Western Australian Herbicide Resistance Initiative (WAHRI) say that the control by some key herbicide groups may be permanently lost, and that evolution of wild radish populations with multiple resistance mechanisms is likely to increase while the emphasis on continuous cropping remains... "Typically the populations have developed resistance to the herbicides that are normally the most effective and the most commonly used to control wild radish... Farmers need to maintain wild radish populations at very low levels using all other feasible control techniques...

Australian Herbicide Resistance Initiative (AHRI) researcher Michael Walsh, who helped compile the fact sheet, said good growing conditions across WA last year had highlighted the difficulty and expense faced by growers in controlling wild radish populations... Dr Walsh said that as well as containing information about wild radish, the GRDC fact sheet contained strategies for controlling weeds including annual ryegrass, brome grass, barley grass, wild oats and flaxleaf fleabane... Dr Walsh said the top priority for growers should be using diverse IWM practices and minimising the number of weed seeds in the soil by preventing weeds from setting seed, or removing any weed seeds before they entered the seedbank...
