Decision making in a dry finish.. Growers will likely get the best outcome from harvesting the crop even if it's going to give a low yield," he said... Growers considering spraying out or cutting paddocks for hay need to consider the history of the crop, including how much rainfall it received early in the season and the extent of any early frost damage, along with weather forecasts in deciding what path to take...

Growers considering spraying out or cutting paddocks for hay need to consider the history of the crop, including how much rainfall it received early in the season and the extent of any early frost damage, along with weather forecasts in deciding what path to take... Both Mr Wooding and Dr Wilhelm agree that unless the plants are dying or dead there is still time for the crops to recover, and a rain in the coming weeks will significantly improve the potential grain yield for many growers...

Researchers anticipate an increase in resistanace to Group B 'imi' herbicdies (e.g. Intervix in annual tyegrass and brome grass in cropping areas as the number of different Clearfield (insert registration symbol) or imi tolerant crop options grows... For tillage situations, 1.6L/ha of Avadex Xtra and 1.5L/ha of trifluralin are commonly used in canola, dependent on soil type (note these rates are too high for cereals)... the sole reason i am using the long fallow followed byrr canola is weed control...

Recent surveys indicate that populations of herbicide resistant annual ryegrass are now more common than susceptible populations across much of the WA wheatbelt... Weed seed removal: Crop topping with herbicides could reduce wild radish seed production and increase retention of pods on plants that could be removed at harvest... Further research is required to refine the mixtures and the new products to use as alternatives to trifluralin # in collaboration with relevant chemical companies and grower groups - and communicate the most effective mixtures or products in subsequent GRDC projects...

Conference puts weeds challenge on stage.. Research by Mike Ashworth, from the Australian Herbicide Resistance Initiative, and research by Dr Catherine Borger, from the Department of Agriculture and Food, WA, were seen as notable examples of the increasing sophistication and potential for innovative weed control, but also of the mounting challenges... Mr Ashworth's research has shown that wild radish has the potential to evade harvest weed seed management if this tactic is overused because it is likely to inadvertently select for wild radish with earlier flowering dates...
