" 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...

disease control using fungicides is an economic decision... fungicide timing Factors that influence spray timing recommendations include: growth stage; level of disease; length of the grain fill period; crop yield expectations; whether the region/season is high or low rainfall and if an early seasonal cut-off is expected; the resistance rating of the variety; and the likelihood of disease... Factors to consider in making this decision are: the presence of disease; yield potential; potential loss of yield and quality; commodity prices; and cost of fungicide plus application...

Caption : DAFWA researcher Ravjit Khangura says research shows that all registered fungicides are effective and that controlling sclerotinia consistently increases crop yields in areas with high disease pressure... The research led by Dr Khangura, supported by the Grains Research and Development Corporation (GRDC), shows all registered fungicides are effective and that controlling sclerotinia consistently increases crop yields in areas with high disease pressure... 2013 trials in WA Research led by Dr Khangura in 2013 built on trials conducted in previous years investigating the optimum time to apply foliar fungicides, to help growers cost-effectively manage sclerotinia...

Monitoring canola crops for blackleg and sclerotinia is essential for making informed decisions about managing these diseases.. The Blackleg Management Guide fact sheet available on the GRDC website describes how to monitor crops and lists all the management practices available.. Dr Lindbeck says foliar fungicides need to be considered in districts at high risk of disease development (areas where disease frequently occurs and where canola has a long flowering period and there is reliable spring rainfall)...

Growers in southern NSW are used to dealing with frost at flowering in spring, and switching to slow maturing cultivars when sowing early is essential to avoid flowering frost damage... "To put 2014 into perspective, early sowing of slow maturing cultivars in southern NSW did not work as well as it has in previous years, but it wasn't terrible and this was the first year for a very long time where sowing early wasn't by far the most profitable thing to do," Dr Hunt said... "We have to learn what we can from 2014 in order to manage these risks into the future."..
