Although residual herbicides will limit recropping options and will not provide complete control, they are a key part of successful fallow management.. The experiment showed that some of these populations were still only suppressed when sprayed with 12.8_L/ha... The most recent survey has focused on non-cropping situations with a large number of resistant populations found on roadsides and railway lines etc where glyphosate alone has been the principal weed management tool employed...

The use of a mouldboard plough with a skimmer attached, that fully inverts the soil to bury weed seeds from on or near the surface to a depth of 15 cm or more, would result in a dramatic reduction of seedling emergence for the majority of weed species... Crop Updates is a partnership between the Department of Agriculture and Food, Western Australia and the Grains Research & Development Corporation 282.. We still have many years ahead of growers experiencing the hardships of resistant weed management before they turn the corner and get on top of the problem...

Growers armed to fight herbicide resistance (West, 6 April 2010).. An army of grain growers is spreading out across Western Australia, kitted out with the latest weapons to fight herbicide resistance after attending a recent series of Integrated Weed Management (IWM) workshops in Moora, Wyalkatchem, Darkan, Nyabing, Green Range and Kendenup... Coordinated and presented by Andrew Storrie of Agronomo, the workshops highlighted the need to take action on weeds, and particularly seed banks, to delay the establishment of resistance and deal with it once it occurs.

Another new glyphosate resistant species confirmed in northern NSW.. Glyphosate resistant population of sowthistle show dead susceptible plants in the right foreground... "Sowthistle and other surface germinating weeds are becoming bigger problems with the widespread adoption of reduced tillage agriculture and an over-reliance on glyphosate," stated Tony Cook, Technical Specialist (Weeds) with NSW Department of Primary Industries and leader of the team that conducted the testing...

Research has demonstrated the profitability of controlling summer weeds early, which increases soil water and nutrients available to the next season's crops, boosting their yields and grain quality... Mr Storrie has helped update Grains Research and Development Corporation (GRDC) resources that can guide growers on pre-harvest herbicide application to control weeds in winter crops, and post-harvest control of summer weeds... Mr Storrie said controlling germinating summer weeds in-crop, where possible, would give growers a head start on summer fallow management and lead to more water being retained in the soil, as well as extra nitrogen being available to crops in the next season...

Reap winter crop dividends from summer weed management.. John Cameron from ICAN, who co-authored the manual with Andrew Storrie of Agronomo, says weeds in summer fallows rob the next crop of vital sub-soil moisture and nutrients. ".. CAPTION: A crop in which summer fallow weeds were managed (left) and where no fallow weed management occurred (right)...

Mr Storrie and John Cameron, of ICAN, have co-authored a new reference manual Summer Fallow Weed Management , published by the Grains Research and Development Corporation (GRDC), which demonstrates how growers can reap a high return on investment from managing summer weeds... "If growers receive rainfall events of more than 10mm in coming weeks and have a history of fleabane in their district, they are likely to have fleabane germinating in their paddocks," Mr Storrie said... "GRDC funded trials conducted by the Department of Agriculture and Food (DAFWA) have shown that fleabane can most effectively be controlled when plants are at the rosette stage," he said...

H. marinum is widely referred to as sea barley grass around the world, and H. hystrixis known as Mediterranean barley grass... Conditions that favour germination and establishment The seed of common sowthistle can germinate at temperatures in the range 5 C to 35 C. Germination is ultimately determined by moisture availability, as a moist environment is preferred... There is a high proportion of seedling emergence from shallow seed sources, whereas more deeply buried seeds remain dormant and long-lived with a half life estimated at 10 years...

With brief overview notes summarising key aspects of weed management, links to valuable resources on weed-related topics and self-assessment questions and an swers, the free-of-charge IWM Hub is a fast way for growers and advisers to evaluate what they do and don't know and be directed to key resources to learn more... GRDC Manager Delivery Platforms, Tom McCue, says the IWM Hub web pages provide a "one-stop shop" for detailed reference documents to enable growers and advisers to implement and communicate cost-effective weed management programs in the face of increasing weed resistance to herbicides... It is important that the grains industry has access to up-to-date information on IWM so growers can continue to grow crops in a viable and sustainable way well into the future...
