Victorian field pea growers can now access information online to assist in reducing the risk of blackspot infection in this year's crops... Supported by the Grains Research and Development Corporation (GRDC), the Blackspot Manager model for Victoria was developed by Dr Moin Salam of Department of Agriculture and Food, Western Australia, and is run in conjunction with the Victorian Department of Environment and Primary Industries... Mature blackspot spores are released into the air from infected stubble following a rainfall event...

The SMS service will give growers direct information about sowing dates that offer the best potential for reducing blackspot in field pea crops," said Ms Davidson... Blackspot Manager was developed by the Department of Agriculture and Food, Western Australia, to predict the release pattern of airborne spores for different regions in an individual season... Ms Davidson said other factors that assist in minimising the incidence of blackspot include avoiding planting pea crops adjacent to pea stubbles and avoiding water logging...

"Using the extensive evaluation enables the Blackspot Manager to predict disease on a farm or a catchment basis.".. To account for this, the South Australian Disease Risk model (DIRI) brings together management factors such as the number of years since a pea crop was grown in a specific paddock, variety, the use of seed dressings and rainfall data... "Our model not only allows growers to see the impact of adjusting sowing date on the level of blackspot disease risk, but also of paddock choice and the use or omission of a seed dressing."..

" Date: 24.06.2008 blackspot mangager Identifies a low risk sowing date for field peas.. Blackspot Manager' calculates the timing of this spore release using seasonal rainfall and temperature data, and identifies whether the delay in sowing is necessary in the current season or whether it is safe for peas to be sown during the autumn... { A time of sowing trial at Kingsford was assessed for blackspot and the peas sown on 14 June had an extremely low infection, validating the prediction made by 'Blackspot Manager'...

Spread of bacterial blight is limited in PBAPercy and PBAOura field peas compared to Kaspa ... Ascochyta blight of lentils survives at least three years within a paddock... Lesions were more likely to occur in crops of Nugget, PBAFlash or Nipper if Nugget or PBAFlash lentils had been grown in that paddock the previous 2 or 3 years...

Department of Agriculture, Fisheries and Forestry (DAFF) principal pathologist Greg Platz said there was a lack of evidence to suggest that the black spotting was caused by spot form net blotch and fungicide applications would be a costly and ineffective means of control... "It is logical to conclude that the black spotting we are currently seeing on some barley crops in the northern region may be spot form net blotch as the symptoms are very similar to the early stages of the disease," Mr Platz said... "Spot form net blotch has seldom been isolated from samples tested and we believe the cause is physiological leaf spotting (PLS), or oxidative stress, largely as a result of current environmental conditions...

Bonnie Hargreaves was awarded a GRDC undergraduate honours scholarship to investigate black spot in field peas to better understand how to breed for resistance.. Individual plants were found with resistance to black spot and early flowering times suitable for southern Australia: " the correlation between the two traits indicated that later flowering times meant better resistance to black spot," she says... Professor Kadambot Siddique, director of the UWA Institute of Agriculture, says that while moderate resistance to black spot has been found in existing field pea germplasm, this new breeding method coupled with new genomic technology could speed up genetic improvements for black spot resistance and other desirable traits...

SARDI senior pulse pathologist, Jenny Davidson, says the model indicates that blackspot will remain a risk for field peas until May 25 in many areas of SA... "The SMS service gives growers direct information about sowing dates that offer the best potential for reducing blackspot in field pea crops," said Ms Davidson...
