In 2013 pod infection was observed in all monitored regions of Victoria... Pod infection will result in seed infection.&nbsp; Infected seeds may die and shrivel and/or cause pod shatter, reducing yield... Even if flower petals are infected, dry conditions or cool wet conditions during petal fall will prevent stem infection development.<strong> <br></strong></li> </ol><h3>Research findings in 2013</h3> <p>In 2013 sclerotinia was observed in all canola producing states it was more severe in North Eastern Victoria, NSW and WA...

" 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...

National canola Sclerotinia surveys have found stem infection levels above 60 per cent in some paddocks in conducive seasons... "But the disease is highly weather sensitive and the crop response will change each year, depending on how the season unfolds - particularly in relation to spring rainfall and timing of spore release," she said... Remotely sensed data from satellite, drones or real time NDVI sensors might allow growers to measure crop biomass and vary fungicidal applications ...

Plan canola rotations to stop sclerotinia stem rot this season.. Dr Khangura said this was due to seasonal conditions causing overlapping of flowering time and coinciding spore release events with flowering in early and late maturing varieties... Other research into sclerotinia in WA will focus on: determining yield losses from disease; continuing work into the efficacy and profitability of crop management practices and fungicide use and timing; and an ongoing assessment of spore release, petal infection and stem rot levels to improve epidemiological knowledge...

Dr James Hunt, pictured, says planting a range of cultivars at their optimal sowing time can improve profitability for wheat growers... Sowing a range of cultivars in their ideal sowing windows will give wheat growers the best chance of balancing the increasing risks of heat and frost damage... Wedgetail, Cutlass, Trojan, Mace 10 April - 15 May "Three years of trials across multiple environments in SA have shown that yields decline at a rate of 28 kg/ha per day once sowing extends past the end of the first week in May," Dr Hunt said...
