We conducted 56 replicated plot experiments on a range of integrated disease management (IDM) strategies under this project aimed at reducing losses and refining management of these diseases... Three replicated trials were conducted in 2007 with 24 different treatments evaluated for the control of CR in both a bread wheat and durum variety... In collaboration with CAS, we tested stubble samples from 312 paddocks in northern NSW for levels of CR and CRR during this project...

Until such varieties are released, northern growers and advisers need to select varieties firstly on the basis of crown rot risk and then manage for stripe rust ... There is a risk of WSMV being spread through infected seed into new areas... We have not been able to determine an economic threshold for RGB in sorghum from these trials...

" Date: 28.09.2010 HIGHER NITROGEN NUTRITION INCREASES THE SEVERITY OF STRIPE RUST.. Significant increases in the severity of stripe rust with higher levels of N application did not appear to be associated with increases in canopy size (biomass), which is believed to provide a microclimate more conducive to stripe rust infection... In one study, increases in the severity of stripe rust and stem rust were observed with the application of nitrate-N, but decreases were observed with ammonium-N, although both N forms would have been expected to increase canopy size...

Crop Updates is a partnership between the Department of Agriculture and Food, Western Australia and the Grains Research & Development Corporation 49.. The wetter than normal conditions over summer may cause the early spore production from the 2008 stubble posing the risk of major spore showers coinciding with the susceptible seedling stage of the crop... Cultivars that lack the receptor gene are easily identified using either molecular markers or the reaction to the ToxA protein and are more resistant to SNB and YS. We suggest that growers avoid using cultivars that contain the receptor gene and are more susceptible to SNB/YS...
