Caption: Leaf blotching in Bannister oats caused by septoria... Research has shown that foliar fungicides can significantly reduce the severity of the disease septoria blotch in Bannister oats and applications around the time of flag leaf emergence appear to be most effective... Mr Gray says that in lower disease situations, where infection hits the canopy later in the season, a single application at or around flag leaf emergence is likely to be able to protect crop leaves, help prevent infection developing in the mid and upper canopy and provide a yield benefit...

Canola crops in high rainfall areas should be monitored closely for sclerotinia stem rot... The disease cycle of sclerotinia stem rot is complex compared to other plant diseases which is why the disease tends to be sporadic in appearance between years and districts... Research in Australia and Canada has shown that the relationship between the presence of the pathogen (as infected petals) and development of sclerotinia stem rot is not very clear due to the strong reliance on moisture for infection and disease development...
