To Keep your herbicides: stop survivors from setting seed.. Keeping weeds 'off-balance' by mixing up controls and keeping their numbers low is the aim of integrated weed management (IWM), where different practices are combined to prevent weeds from adapting to a single control option... The interactive, one-day grower workshops focus on how to manage weed populations and ensure that herbicide resistance does not dictate how they farm...

GRDC values the contributions made by its research partners during the 2004 series of Grains Research Updates.. Overall, there were 50 comparisons, 45 showing a positive yield increase with fluid and 5 with no yield difference... Overall, there were 11 comparisons, with 4 yield decreases due to fluids and 7 with no yield differences...

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...

A positive test result confirms the need for alternative tactics or herbicides... Assessing weed population density The most accurate way to estimate the population of a weed in a paddock is to count the number of plants in an area of known size at a number of locations... Estimating potential weed population density Potential weed population density can be estimated in a number of ways, such as: When weeds are setting seed, count the number of seed-heads or pods, and the number of seeds per pod or seed-head, from a given sample area...

While the adoption of genetically modified canola has been less widespread than originally anticipated by Australia's oilseed industry, Roundup Ready (RR) canola has been highlighted in this project as a very useful tool for integrated weed management (IWM)... RR canola continues to be promoted as a very useful tool as part of an integrated weed management (IWM) package in the Southern and Western regions, to reduce weed numbers and allow a broader rotation of herbicide groups... As a part of this project, Dr. Linda Hall, associate professor in the Faculty of Agriculture Life and Environmental Science at the University of Alberta, was keynote speaker at the 2012 BCG trials review day...

The Weed Seed Wizard is helping farm advisors and their grain grower clients make more informed weed management decisions that will reduce weed seed banks and the cost of controlling those weeds... Then further developed into a 56.489: more user friendly decision support tool by these R&D partners in a GRDC supported project, 63.29: nationally coordinated by Sally Peltzer of WA 69.27: What the Wizard can do is take real farm data such as what weed species are present; herbicides 74.96: used; when they were applied; rainfall records; what crops where sown and when, and their 79.969: harvest dates; and use that data to calculate the rise and fall of the weed population throughout 85.329: the year and over a number of years... 187.099: Cameron Weeks: Say a chaff cart is going to cost you 60 thousand 190.459: dollars, we can easily calculate what that 196.609: amortize over time etc...

The Weed Seed Wizard is a computer simulation tool designed to help gr owers understand and manage weed seedbanks specific to their farms... Thank-you to GRDC for funding this project and to the rest of the Weed Seed Wizard team; Gurjeet Gill (Uni of Adelaide, Hanwen Wu and Eric Koetz (DPI NSW) and John Churchett and David Thornby (DEEDI Qld) for their input into the model...

Narrow windrow burning is a simple, low cost way of destroying weed seeds and can significantly reduce weed seedbanks... Concentrating weed seed bearing chaff and straw fractions into narrow windrows during harvesting increases the potential for weed seed destruction when the residue is burned in autumn... Some growers claim that placing the chaff and weed seed fraction on top of the straw windrow destroys more weed seeds because these are in the hottest part of the fire when stubble rows are burned in autumn...
