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...

Keep an eye on your canola for diseases in 2015.. We want growers to have a fungicide management plan in place for when new actives come onto the market and we are also encouraging growers to change varieties based on resistance groups... Dr Marcroft says at the end of the season, growers should pull some canola plants out of the ground and cut the stem open to see if they have blackleg symptoms...

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...

If fungicides are required, make sure they are applied in the early stages of the epidemic... Spot form of net blotch (SFNB) was the dominant foliar disease of barley, causing yield and quality losses where susceptible varieties were grown in infected stubble and left untreated... In addition to mixing or rotation of fungicides an integrated approach to disease control that includes crop rotation and avoidance of susceptible cultivars will reduce inoculum loads, and reduce the likelihood of resistance to fungicides developing...

Changes in Septoria tritici blotch resistance to fungicides have been detected in the southern grain growing region, especially where wheat is sown into wheat stubble... Two gene mutations in STB detected by NSW Department of Primary Industries indicate resistance to some fungicides (see Case Study)... Currently none of the products with an azole/strobilurin combination in Australia used on wheat are registered for use on STB...
