It is understandable why growers are keen to control weeds along fence lines and crop margins... AGSWG Chairman Dr Chris Preston, from the University of Adelaide's School of Agriculture, Food and Wine, says the main factors that contribute to glyphosate resistant weeds are: intensive use of glyphosate; lack of competition; no other effective herbicides employed; and little or no other weed control practices employed... Many growers prefer to use glyphosate alone for weed control on fence lines due to its ease of use and low cost," Dr Preston said. "..

Brome grass 1 Growers urged to be vigilant as brome grass found to be resistant to glyphosate A population of Great brome grass (Bromus diandrus) from South Australia has been confirmed resistant to the world's most important herbicide, glyphosate... This is the first time that this highly competitive annual grass weed of crops and pastures has evolved resistance to glyphosate and is the third Australian weed species confirmed as resistant to glyphosate in the past 12 months... This is a huge concern to Australian grain growers because this highly competitive weed has been becoming a major problem in reduced-tillage farming," said Associate Professor Chris Preston, chair of the Australian Glyphosate Sustainability Working Group and leader of the University of Adelaide team which confirmed the result.

Wild radish joins the glyphosate resistance club.. GRDC-sponsored PhD student Mike Ashworth, at the Australian Herbicide Resistance Initiative, has uncovered glyphosate resistance in wild radish... Populations of wild radish screened at the Australian Herbicide Resistance Initiative in WA showing three known susceptible (left) and one glyphosate-resistant population (right) when exposed to 750 grams per hectare of glyphosate (which is above the recommended rate for wild radish control in Australia)...

The Central Queensland (CQ) region, including the Central Highlands and Dawson/Callide subregions, is home to some 400 grain growers... The CQ production environment is characterised by a summer dominant extremely variable and often marginal rainfall... In response to the complex, flexible and risky CQ production environment, grain growers have developed a highly opportunistic production system that is based on maximizing the use of rainfall...

The use of Group A herbicides in fallow to control grass weeds such as the Chloris species - feathertop Rhodes grass (Chloris virgata) and windmill grass (Chloris truncata) - have shown to be a viable option for controlling young weeds... Recent research has investigated the use of some of these herbicides for fallow applications to control grass weeds, in particular the Chloris species - feathertop Rhodes grass (Chloris virgata) and windmill grass (C. truncata)... Trial results have shown that a minimum period of 5 to 7 days should occur between applications...

Small, early tillering weeds should be the target of Group A herbicides; these herbicides are less effective when weed size increases.. Many northern growers are now dealing with grass weeds in fallow that are not well controlled by glyphosate, with grower feedback indicating that alternative solutions to control these weeds are required... Research by the GRDC-funded Grower Solutions Groups has demonstrated that the use of Group A herbicides in fallow can be a viable option to control young grass weeds in certain situations...
