University of Adelaide scientists mapping the extent of herbicide resistance in annual ryegrass across southern Australia's high-rainfall zone (HRZ) have concluded that pre-emergent herbicide use is essential... The GRDC-supported research, involving varying weather patterns, topography and soil types, indicates options such as Sakura plus Avadex Xtra or Sakura followed by Boxer Gold post-emergent can provide effective control of annual ryegrass in the HRZ... The university's research included random farm surveys across south-eastern Australia to map ryegrass herbicide resistance in the HRZ, and the findings from these surveys will be incorporated into a new national resistance-mapping tool developed by Bayer (see Weed resistance maps help navigate herbicide options )...

The severity of herbicide resistance around Dubbo, central New South Wales, has stunned researchers and growers alike, with several weed species demonstrating resistance to multiple modes of herbicide action... Researchers suggest that using non-herbicide methods of controlling weeds may have to become the norm in the future to overcome herbicide resistance... Maurie Street, chief executive officer of GOA, says more than 120 samples of annual ryegrass, black (or wild) oats and wild radish were submitted for testing in just two days: "We only expected to receive 30 or 40 samples," he says...

The project was designed to provide growers with information on the herbicide tolerance of new pasture legume species... As part of Project DAW00031, 90 yellow serradella accessions were evaluated for their tolerance to MCPA and metribuzin # across two replicated glasshouse experiments after laboriously extracting 150-250 seeds per accession by hand from pod segments... Initially all the accessions were evaluated for their tolerance to Jaguar, Lexone, MCPA and Tigrex over three experiments...

With herbicide-resistant weeds an increasing problem across the northern grains region, experts are looking to Western Australia for alternative methods of controlling weeds... Maurie Street from the Grain Orana Alliance says herbicide resistance is an increasing problem in northern grains production because many farming systems have moved to continuous cropping with nearly 100 per cent reliance on herbicides for weed control... Windrow burning is cheap and easy to set up, allowing growers to test the 'proof of concept' on their farms before making large investments in chaff carts or seed destructors "We need to start looking at new techniques for weed control - we shouldn't be expecting or relying on new herbicides to fix the problem," Mr Street says...
