Ask an expert about harvest weed seed control.. The Weedsmart `Ask an Expert' theme is currently focussed on harvest weed seed control and is being hosted by Dubbo farmer, and researcher with the Grain Orana Alliance, Maurie Street... WeedSmart is an industry-led initiative managed by the Australian Herbicide Resistance Initiative (AHRI) and supported by the Grains Research and Development Corporation (GRDC) that aims to enhance on-farm practices and promote the long term sustainability of herbicide use in Australian agriculture...

Controlling weed seed at harvest may be growers' best line of defence in combatting the on-going battle against herbicide resistance... With headers now dotted across winter crop paddocks in New South Wales and Queensland, the Grains Research and Development Corporation (GRDC) is reminding growers that driving down the weed seed bank is critical to managing herbicide resistance... "Driving down the weed seed bank is growers' best defence against herbicide resistance and that centres on two key considerations - dealing with the weed seeds already existing in the soil and stopping additional weed seeds from entering the soil...

Offensive arms growers with tools to fight resistance.. WeedSmart provides a practical and innovative tool kit of resources for advisers and growers to keep weeds - and herbicide resistance - at bay... WeedSmart encourages growers to knock out 100 per cent of weeds at every opportunity, implementing chemical and non-chemical weed control measures throughout a season, reducing weed seed banks and preventing weeds from setting seed and spreading resistance...

Growers embrace herbicide resistance management 102.. Ms Heuston said while growers were aware of the non-chemical tools available to manage the problem, many were unsure of the economics and practicalities of adopting them for weed seed management... "The purpose of the trip was to encourage central western farmers, many of whom have started to undertake some herbicide resistance management strategies, to interact with other growers who are a lot further down the track in managing this issue," Ms Heuston said...

The Weed Seed Wizard was developed in WA and is being brought to Queensland and NSW with support from the Grains Research and Development Corporation (GRDC)... Mr Congreve says Weed Seed Wizard can be fine-tuned to individual farms using local weather data, soil type and management options... "The Weed Seed Wizard can help advisers understand and predict the impact of weed management decisions on crop yield and weed seedbanks."..

CSIRO Agriculture's Dr James Hunt says APSIM modeling indicates that - even with WA's Mediterranean climate - sowing opportunities in this State occur often enough so that adoption of longer maturing varieties for earlier planting has potential to increase whole farm wheat yields, particularly in medium and high rainfall zones... The trials will be repeated this year and the aim is to assess whether long maturing varieties sown early in the year can yield as well as - or better than - short maturing varieties (such as Mace ) when these are sown in their optimal window in WA environments... Dr Hunt says using a variety such as Whistler to bring sowing dates forward would allow growers to take advantage of early planting opportunities across a broad window from late March to early May and its stable flowering date would reduce frost risk...

Non-herbicide weed control strategies are being employed over large areas of the Western Australian grainbelt at harvest time to reduce the weed seed burden and manage resistant weeds... Techniques including windrow burning, chaff carts and the Harrington Seed Destructor drive down the weed seed 'bank' to very low numbers, making weed control easier, even in the face of herbicide resistance... "Topics that will be explored include why to consider harvest weed seed control; what options are available; what paddocks to target; and how to achieve success," ICAN senior consultant Mark Congreve said...

Conducted by Independent Consultants Australia Network (ICAN) and sponsored by the Grains Research and Development Corporation (GRDC), the webinars will focus on a different topic each week: managing fleabane in zero-till farming systems, spray application in summer fallows, and understanding stubble and soil binding of pre-emergent herbicides used for ryegrass control in winter crops... ICAN's Mark Congreve says advisers can simply use their laptop or personal computer to link into each 30 minute presentation from industry experts in their field, after which webinar participants can ask the presenters questions... Caption: Dr Dale Shaner (left), from Colorado in the USA, will be the presenter of a webinar on understanding stubble and soil binding of pre-emergent herbicides used for ryegrass control in winter crops...

Control the seeds to control the weeds.. Effective weed management in productive cropping systems is reliant on preventing viable seed entering the seedbank... "Growers are advised to use an integrated weed management strategy as the most effective method of controlling problem weeds," Dr Widderick says...
