Efficacy of pre-emergent herbicides in different environments** Over the past five years we have been investigating alternative herbicides for control of trifluralin in annual ryegrass... wagga preston Figure 1: Performance of pre-emergence herbicides on trifluralin-resistant annual ryegrass at Roseworthy, SA (higher rainfall site, left) and Berriwillock, Vic (lower rainfall site, right) in no-till wheat sown using knife points and press wheels... Performance of pre-emergence herbicides on brome grass at Wokurna, SA (left) and Waikerie, SA (right) in no-till wheat sown using knife points and press wheels...

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...

Researchers and cropping experts from across Australia will converge on Griffith this month to provide local grain growers with the latest recommendations and advice... The Update will be a valuable source of information and resources for local grain growers as they strive to overcome cropping constraints and boost productivity, according to the chair of the GRDC Southern Regional Panel, Keith Pengilley... One of the challenges facing growers in the region is the spread of herbicide-resistant weeds, and tackling this issue at the Update will be Western Australia-based Peter Newman, representing Planfarm and the Australian Herbicide Resistance Initiative (AHRI)...

The benefits improve crop health and crop competitive ability against weeds and the effectiveness of pre-emergent herbicides... When used as a post-emergent product, little of the herbicide gets to the roots and the control of established weeds is often very poor... benefits arise when the weed is prevented from setting seed as there are no increases to the seedbank and, as a consequence, fewer weeds in the future...

Due to the almost exclusive use of 24.619: this one herbicide some weeds have developed Glyphosate resistance... I think the strategy should be if Trifluralin is still working 242.72: for you, you should be adopting these new herbicides over at least part of the farm 248.4: so you can keep Trifluralin working and if Trifluralin has already failed get into a 253.18: rotation between your group J and group K herbicides and not just rely on one of them 257.97: for all for your weed control... 275.2: Chris Preston: Whether they collect weed seeds with a chaff 279.34: cart, whether they buy a seed destructor, whether they fallow or whatever practice that 286.69: they want to use but they need to be building that into their rotation...
