Opportunities exist for grain growers in the southern cropping region to more effectively manage weeds in retained stubble systems, according to new research conducted by the CSIRO and funded by the Grains Research and Development Corporation (GRDC)... "The data shows very large differences between regions for practices like harvest weed seed control, crop topping and double knockdown which reflects past differences in the levels of herbicide resistance, but we're now seeing resistance issues becoming much more important in all cropping regions," Dr Llewellyn said...

The results of the experiments have given Jeff the confidence to realise that he does have a viable, cost-effective alternative knockdown herbicide to glyphosate... Double knockdown (T 2.2b, page 128) Weather permitting, a double knockdown is implemented on resistant ryegrass paddocks prior to sowing using two non-selective herbicides (glyphosate followed by paraquat + diquat or paraquat, the choice being dependent upon the range of weeds present)... Helpful advice The Grays still enjoy the challenges and can see that they have made enough progress to feel they are being successful in managing a serious annual ryegrass problem...

The use of Group A herbicides in fallow to control grass weeds such as the Chloris species - feathertop Rhodes grass (Chloris virgata) and windmill grass (Chloris truncata) - have shown to be a viable option for controlling young weeds... Recent research has investigated the use of some of these herbicides for fallow applications to control grass weeds, in particular the Chloris species - feathertop Rhodes grass (Chloris virgata) and windmill grass (C. truncata)... Trial results have shown that a minimum period of 5 to 7 days should occur between applications...
