"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."..

The National Brassica Pathology Working Group, comprising pathologists, agronomists, chemical companies and canola breeders from across Australia, unilaterally shared concern at a recent meeting in Melbourne that growers would potentially face serious risk of crop failure due to blackleg if attempting to grow canola on canola... Growers are urged not to risk the long-term viability of the canola industry by sowing canola on canola," said Dr Marcroft, on behalf of the National Brassica Pathology Working Group... Dr Marcroft, who has been addressing GRDC grains research Updates in the southern region about the blackleg scenario, says growers can use the Risk Assessor to determine if their paddocks are in a high risk situation, and what practices could be changed to reduce yield loss from blackleg.

A new Grains Research and Development Corporation (GRDC) fact sheet brings together the latest results and recommendations from nine current cereal disease research projects for northern region growers... Cereal fungicides - Northern Region outlines how and why growers should assess disease risk, including pre-planting tactics such as determining the risks posed by retained stubbles and over-summering weeds and cereal volunteers... Other considerations include the seasonal outlook, variety selection and treatment plans if disease develops quickly...

The incidence of disease, which is the proportion of plants that become infected during the season... The incidence of disease can be predicted before sowing, because it is directly related to the quantity of inoculum (infested crop residues)... The number of plants infected depends on how much stubble there is, and what proportion of this is infested with the fungus...

A reliable and timely crop disease forecast can help growers in managing the disease... With the background, this project is designed to provide grain growers with such tools and/or outputs of the tools as disease risk forecasts to minimise the impact of diseases... The project will deliver two outputs: one, the decision support tools (which forecast disease risk and impact on grain crops) developed from disease epidemiological data, validated in target environments and made available to stakeholders; and two, the current and updated IDM recommendations, support tools and knowledge provided to grain growers in WA, and where applicable in GRDC Southern region, through regular print and electronic publications and in-person extension activities and delivery evaluated against industry needs...

There has been a considerable increase in the incidence of crops affected by root lesion nematode (RLN) throughout the Western Australian (WA) cropping region... The recent root disease survey showed that the highest levels of all root diseases in WA are in the southern high rainfall zone... The objectives of the project are to:1) Identify sites in WA that are suppressive to one or more root diseases of wheat including take-all, rhizoctonia root rot, crown rot and RLN. Sites will be selected from three past and current projects including the DAFWA "Profitable crop sequencing in WA" [P. WHITE, M. HARRIES] project (which will establish 150 focus sites at which inoculum level and disease incidence will be measured), the "Soil Quality" [D. MURPHY] project (which has previously established a large number of geo-referenced monitoring sites around the WA agricultural region and the inoculum level was measured), and the DAFWA 2006-2008 cereal root disease survey sites [DAW00159]...
