stem infection

Catalogue: Broadacre Field Crops DAFF QLD
The disease caused by the fungus, Podosphaera fusca , is favoured by cooler growing conditions and is often widespread in late crops... It can cause significant yield loss if it develops before or at flowering, particularly if the crop is under moisture stress... There are strategies to minimise the risk of TSV infection: maintain farm hygiene, in particular the control of parthenium weed avoid planting mungbeans close to pastures, particularly those containing dense parthenium and other broadleaf weed infestations if crops are planted close to parthenium infested pastures either spray out pasture close to the mungbean crop or leave a buffer avoid planting mungbeans into marginal moisture, especially near parthenium infested pasture ensure planting seed is from crops with no signs of TSV...

Screening for phomopsis (Diaporthe toxica) resistance in albus lupins cowley.. The overall goal of the research is to improve management options for farmers and to assist in the breeding of phomopsis-resistant cultivars... %germination indicated by dashed line; n=300 for each category, LSD5%=6.331; %infected seed indicated by solid line; n=150 for each category, LSD5%=7.581 Screening techniques In 2007 a set of 45 breeding lines, landraces and varieties were subjected to a range of screening assays to determine varietal response and to assess the suitability of each screening procedure...

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)...

Dr Kurt Lindbeck says early intervention is critical in minimising the production impact of sclerotinia stem rot... "Outbreaks of sclerotinia stem rot tend to be sporadic, with levels of disease varying between seasons and regions in southern NSW and northern Victoria, so our advice is for growers to get out into their crops to monitor the situation... "The disease can cause yield reductions of 30 to 40 per cent in heavily infested crops in high-rainfall years, and last year the first warning signs appeared in early August, with apothecia observed in canola crops in southern NSW, and continued wet weather through the month providing periods of extended leaf wetness and opportunities for disease epidemics to develop."..

Clean or grade any retained canola crop seed from last season showing signs of Sclerotinia sclerotiorum (or sclerotia) fungus - or use new clean seed.. Caption: Keep a watch for sclerotinia this season, as Sclerotinia sclerotiorum (or sclerotia) fungus from seasons 2013 and 2014 will have survived in the soil... Bayer CropScience technical adviser north, Rick Horbury, told the recent West Midlands Group GRDC-DAFWA Regional Crop Update meeting that of concern for 2015 is that Sclerotinia sclerotiorum (or sclerotia) fungus from seasons 2013 and 2014 will have survived in the soil...

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...
