Condo hosts cereal rust workshop

On Thursday August 19 a Cereal Rust Workshop was held at the Condobolin Research and Advisory Station for Advisors and Growers. The meeting was well attended with around 35 growers and advisors from across the Condobolin and Forbes district in attendance.
The guest speakers for the morning session was Associate Professor Colin Wellings, Sydney University, Plant Breeding Institute, Cobbitty, Peter Matthews, acting Technical Specialist (Cereal Farming Systems), Temora and Ian Menz, District Agronomist at Condobolin.
The session covered the history of cereal rust within Australia and how the disease has developed since being detected in Australia and the origins of different pathogens within Australia at the present time. Colin presented the findings from last seasons rust survey and the likely risks to cereal crops in 2010.
Concurrent sessions were conducted, providing information on rust reaction and variety selection. Colin displayed the disease reaction to different stains or pathogens of rust on many of the current wheat varieties, as well as identification of rust on plants. In this session, the take home message was variety selection as it is important to select a variety with a high resistance level.
Peter and Ian of Industry and Investment NSW conducted an information session on the disease effects and condition required for the disease to develop as well as providing information on current fungicide treatments. In this session the timing of fungicide application was noted as the take home message.
It is very important to carry out regular crop monitoring to achieve early detection of disease. It may be necessary to apply one, two or even three application of fungicide to maintain the protection of the flag, minus one and two leaves, which are the “money leaves” of the plant. The use of seed dressing was also discussed as this provides early seedling and plant protection to delay foliar fungicides application.
