Maurie Street, Grain Orana Alliance (GOA) chief executive officer says growers who have their winter cropping program planned and ready to go will benefit if they are able to use a potentially short planting window to best effect... "The key to a successful planting this year will be being prepared across the farming system by putting some thought into nutritional requirements, a planting program taking into account wetter paddocks and crop selection," Mr Street said... Mr Street said there was likely to be big canola planting in the central west this year due to depressed wheat prices...

The agronomist from Dubbo, New South Wales, says two years of survey data show herbicide resistance is increasing at an alarming rate across the central western NSW cropping belt and growers need to change tactics urgently to develop effective, long-term weed-management strategies... "In the GOA surveys both ryegrass and black oats demonstrated a high incidence of resistance, with 100 per cent of the ryegrass and 86 per cent of black oats showing resistance to at least one herbicide," Mr Street says... Before growers and agronomists decide on a course of action, Mr Street says it is critical they start testing survivor weed samples so they can map the resistance status of individual farms and paddocks as part of the process to develop effective long-term strategy for the management of hard-to-kill weeds...

"Windmill grass has been confirmed as glyphosate resistant and is quickly becoming one the region's most problematic weeds in zero tillage summer fallows," Mr Street said... Mr Street says windmill grass has rapidly increased in prominence in CW NSW cropping paddocks over the last four to five years, especially in zero tillage systems... "Windmill grass has shown to be very difficult to control in zero tillage systems with herbicides," he said...

Grain Orana Alliance (GOA) chief executive Maurie Street says each weed variety has a critical temperature to burn at, for the seed to be destroyed - for example, ryegrass seeds must burn at 400 o C for at least 10 seconds to be effectively destroyed... Mr Street said the right preparation through harvest and choosing the right time and conditions to burn were the keys to ensuring a successful burn... "Burning when the weather is too hot increases the chance of fire escapes, but burning when it is too cold can mean the critical temperatures for seed kill is not achieved," Mr Street said...

The weed has been a priority for the Dubbo-based GOA in its three years of operation, funded by the Grains Research and Development Corporation (GRDC) to fast-track extension of research to growers in the NSW central west... "We're thinking outside the square, so it's not just different application rates and timing of the usual herbicides; trials will look at different herbicide groupings, where residuals might fit, and knock-down alternatives," Mr Street said... "The long-term solutions are most likely to be in the weed's ecology and other control options - and the GRDC is proactively supporting many projects looking into those solutions" Mr Street said...

Narrow windrow burning at night.. Grain growers in the southern cropping region are being encouraged to now start thinking about using narrow windrow burning as a weed seed control tool to be employed at harvest this year... Grain Orana Alliance chief executive Maurie Street says for narrow windrow burning to be successful, growers should plan for its use "a long time before they strike a match"...

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...
