" Date: 09.12.2013 'Perfect storm' sparks sclerotinia outbreak in canola crops.. " , crops have flowered very early this year due to the mild winter temperatures and this has contributed to the levels of disease we observed," said Mr Lindbeck, who is based at the Wagga Wagga Agricultural Institute where he leads Grains Research and Development Corporation-funded research on the management of pulse and oilseed diseases in southern NSW... Mr Lindbeck said that in addition to sclerotinia being an airborne disease, the sclerotinia stem rot pathogen produced hard, black, survival bodies on infected plant tissue called sclerotia which enabled the fungus to survive for up to 10 years in the field...

The large areas sown to canola in 2011 and the predicted increases in the area sown to canola in 2012 in southern NSW and northern Victoria will increase blackleg severity and increase the likelihood of yield losses... The aim of the work was to investigate the use of foliar fungicides on canola seedlings as an alternative or in addition to the application of a seed dressing for blackleg control in areas of high disease pressure... Results from the field experiments suggest that the addition of a seed dressing and the application of a foliar fungicide gave the best protection...

If there is a history of sclerotinia stem rot in your district causing yield loss, be prepared to use a foliar fungicide to reduce yield loss... Research will be conducted to investigate this issue in 2014... We can use the fungal life traits to manipulate the fungal population, by changing cultivars with different sources of resistance, the selection pressure on the fungal population is constantly changing...
