Glyphosate resistance survey finds SA growers at risk.. The random survey, conducted by the University of Adelaide and funded by the Grains Research and Development Corporation (GRDC), has shown it is time for farmers to make significant changes to weed management to halt this problem... "We knew there was some glyphosate resistance in the area from previous work," stated Associate Professor Chris Preston of the University of Adelaide and project leader, "but this surprised all of us and has set the alarm bells ringing to bring in changes to weed management...

Time is right to fight flaxleaf fleabane.. "When treated young, at one month or less, susceptible flaxleaf fleabane plants in fallow can be controlled with glyphosate quite often a glyphosate mixture or double knock is required for optimal control," Dr Widderick said... For rosette control in fallows Dr Widderick said the most consistently effective treatments were double-knocks (sequential application), particularly with glyphosate and Tordon 75-D followed seven days later with Spray...

Fleabane is now recognised as one of the major difficult-to-control weeds in northern New South Wales and southern Queensland... Recent research by the DPI&F showed that glyphosate alone is normally ineffective, except on very small weeds... Our research has shown that Amitrole T could be strategically used as a late treatment to target mature survivors...

With 'single knocks', 'double knocks' and residual herbicides, growers in the northern region are successfully fighting back against fleabane.. Fleabane is a wind-borne, surface-germinating weed that thrives in areas of low competition and which proliferated in the northern region as growers moved towards reduced and no-till farming... Fleabane proliferated in the northern region but has spread south and west as more growers adopt no-till and reduced-till farming...

Herbicide control of fleabane is difficult because it has a natural tolerance to herbicide uptake and is often targeted over summer when plants are well established and spray conditions are not favourable... In southern New South Wales it emerges through winter and early spring, whereas recent studies have found that populations from South Australia emerge as late as August to November, provided moisture is not limiting (see Figure 1)... The impact of fleabane control on stored soil moisture was also assessed in April for a selection of treatments at Bute and Pinnaroo (Figure 3.)...

Early control thwarts fleabane.. Tony Cook, NSW Department of Primary Industries (NSW DPI) weeds technical specialist based at Tamworth says prevention is better than cure when it comes to controlling fleabane and he recommends pre-emergent or seedling management... Mr Cook says fleabane has spread largely because it thrives in the no-till farming system due to its surface-germinating seed which, under this system, lies undisturbed by tillage or soil coverage...

Some populations of the weed are resistant to glyphosate as a result of this herbicide being relied upon repeatedly and almost exclusively for weed control in fallows... An additional range of single and double-knock treatments have been evaluated for fallow control of fleabane across Qld and NSW... Specifics of rate and product have been deleted from the above figure as NONE of the herbicides listed are registered for the control of fleabane...
