Three drivers influence the incidence of plant disease: the host the environment the pathogen... Aspects of the host promoting disease are the growing of susceptible crop varieties, and widespread and sequential sowings of hosts susceptible to specific pathogens... The legacy of the floods and rain included transport of inoculum (crown rot, nematodes, leaf spots through movement of infected stubble and soil), development of sexual stages (leaf spots, head blights), survival of volunteers (unharvested material and self-sown plants in double crop situations) and weather-damaged seed...

South Australian field pea growers can now access information online to assist in reducing the risk of blackspot infection in this year's crops... SARDI senior pulse pathologist, Jenny Davidson, says the model indicates that blackspot will remain a risk for field peas until May 25 in many areas of SA... "The SMS service gives growers direct information about sowing dates that offer the best potential for reducing blackspot in field pea crops," said Ms Davidson...

Yellow spot is estimated to cause crop losses of $140 million annually in Western Australia.. A world-first molecular breakthrough by Western Australian researchers is advancing efforts to breed wheat for resistance to yellow spot (also known as tan spot)... In an attempt to cut losses from yellow spot, the GRDC and Curtin University's Centre for Crop and Disease Management (CCDM) started a national 'Stop the Spot' campaign this year calling for growers to send in suspect wheat crop leaves for disease testing...

Victorian Department of Primary Industries cereal pathologist Dr Grant Hollaway is quantifying yield losses in wheat caused by yellow leaf spot... Scientists are to pinpoint the yield losses attributed to YLS, a disease that is widespread in medium to low-rainfall districts, particularly where stubbles are retained and wheat is grown in tight rotations... Some growers are relying on fungicides for YLS but are unlikely to be achieving complete control of the disease...
