Catalogue: GRDC Final Reports
The project has made excellent progress in identifying key genes linked to oxidative stress that, when mutated, make the model plant Arabidopsis highly susceptible to AG8... The project has also identified other genes whose expression is highly induced following R. solani infection in Arabidopsis and wheat... The exciting results were further supported by large scale analysis of gene expression that revealed the resistance to AG8 was associated with the activity of a number of genes linked to the generation of ROS and similar induction of ROS related genes was seen in wheat after AG8 infection using microarrays...

Many decisions to manage crop establishment pests should be made well before sowing when there are far more control options available... Extremely high levels of resistance to several synthetic pyrethroids (> 200,000 fold in the case of bifenthrin) were detected using laboratory bioassays, and this has translated to significant yield losses in the field... Further properties with insecticide resistance have been detected since 2010, although at this stage, resistance has not been detected outside of WA. Experts predict resistance in RLEM will spread to other states, including to Victoria...

Locusts give a lesson in practical farming.. The defence of their crops became a lesson in strategic thinking and the use of all available knowledge, an experience he feels will prove invaluable time and again in his future career as a professional grain grower... The 22-year-old, working with his father Jon and brother Marc, relied on a multi-faceted response, combining their knowledge of agricultural systems, the experiences of other growers, plus official recommendations to protect the family's 5260ha wheat crop...

Strategic tillage puts the pressure back on weeds.. The planting technology combines the functionality of a harrow for breaking up soil clods, removing weeds and covering seed on tilled paddocks, with that of press wheels used to compact the soil over seed in furrows... Using the RFM Ag press harrows to plant Kyabra chickpeas and Kennedy wheat into tilled soil this winter grains season, Darren says they have also cut downtime spent on machinery at seeding...

Research is showing that increased lime use across WA is affecting micronutrient concentrations in crop plants and changing the residual value of these nutrients on acid soils... To assess the micronutrient status of cereal crops, samples of flag leaves are the best bet for tissue testing analysis... Dr Brennan, of the Department of Agriculture and Food WA (DAFWA), says the MPCN team is also finding that liming on acid soils reduces Cu, Zn and Mn concentrations but increases Mo in crop plants and can change the residual value of micronutrients...

GRDC Updates roll out in northern grains region.. Talks on winter crop nutrition, problem weeds and summer crops are attracting good interest from growers as the August round of Grains Research and Development Corporation's (GRDC) Updates rolls out... Conditions remain on a knife edge across the NSW/Queensland border cropping regions as dry weather starts to take an effect on yields but also keeps diseases such as yellow spot and stripe rust at bay at least temporarily...

The term armyworm is derived from the spectacular movement of large numbers of larvae (armyworms) to new feeding areas once an area is eaten out... The solitary phase occurs when larvae are reared in solitary conditions: these larvae show a considerable range of colour variations and are not prone to excessive movement... The movement of either ill-defined or well-defined groups of larvae across a paddock, together with the habit of feeding during daylight hours, led to the name dayfeeding armyworm...
