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...

University of Adelaide associate professor Dr Gurjeet Gill says, at this stage, the weeds are mostly confined to roadsides and some horticultural areas, such as the Barossa and Riverland, but it is likely they will soon invade cropping paddocks... "The seeds of these weeds are readily dispersed by wind, so it's just a matter of time until they are found in crops," Dr Gill says... "In cases such as FTR and windmill grass where herbicide options are limited, integrated weed management principles should be applied to maximise control (see box, right)...

"The seeds of these weeds are readily dispersed by wind, so it's just a matter of time until they are found in crops," Dr Gill says... In a study at Roseworthy in 2014, FTR produced seven tonnes per hectare of biomass over summer, which was six times more than windmill grass...
