COWRA FOLIAR DISEASE WORKSHOP FOR ADVISERS: Cutting edge cereal disease management practices will be the focus of a Grains Research and Development Corporation-supported two-day workshop at Cowra in July... The small group workshop will cover regional solutions and issues including: cereal growth stages and spray decisions; the impact of environment and day degrees on crop and disease development; where new and old fungicides fit; the development of cost-effective disease management plans; and management strategies for key cereal diseases... The workshop, supported by GRDC and the Rust Bust campaign, is locally sponsored by BASF...

The potential for epidemic development can be gauged by the amount of disease in the lower canopy... Cereal seed treatments are widely used throughout the Northern Grains Region (NGR) to control or suppress a broad range of diseases... With a range of diseases that are more difficult to control and a grain fill period less predisposed to drought stress there may be more benefit to strobilurins in barley crops rather than wheat, though more work is needed to verify this statement...

Collective action can minimise barley disease losses.. "Strategies that can help minimise the risk of yield losses include destroying the 'green bridge' including barley volunteers and weeds (to reduce rust carry-over); using appropriate seeding strategies; monitoring emerging crops for signs of disease; and considering using a registered foliar fungicide if the variety is susceptible to the diseases found," Dr Jayasena said... "I encourage growers to monitor the early development of crops for leaf disease symptoms and to consider using a registered foliar fungicide if the variety is susceptible to the diseases found," Dr Jayasena said...

A workshop in Western Australia this autumn will finetune advisers' cereal disease management skills, benefiting growers in what could be a high risk year for foliar diseases... Workshop facilitator John Cameron, of ICAN Rural, said more workshops could be held in the future, depending on demand, and encouraged advisers interested in participating to contact him at john@icanrural.com.au.. "The event will provide the time and experience we need to discuss issues of regional importance and how this is reflected in advice to growers," Mr Cameron said...

PHOTO: Cox Inall Communications "Challenging" is how New South Wales plant pathologist Dr Andrew Milgate describes the disease pressure last winter and he says the message for cereal growers this season is to be vigilant about root diseases and adopt an integrated approach to disease management... "We need an integrated strategy to tackle winter cereal diseases in southern NSW, because during years like 2015, when we have an early sowing and a wet winter, the conditions are ideal for infection and disease development," he said... "All barley varieties should be monitored for infection, sowing barley on barley should be avoided and if infection is detected growers need to consider fungicide applications to reduce potential yield losses," Dr Milgate said...

Three drivers influence the incidence of plant disease: the host the environment the pathogen... Aspects of the host promoting disease are the growing of susceptible crop varieties, and widespread and sequential sowings of hosts susceptible to specific pathogens... The legacy of the floods and rain included transport of inoculum (crown rot, nematodes, leaf spots through movement of infected stubble and soil), development of sexual stages (leaf spots, head blights), survival of volunteers (unharvested material and self-sown plants in double crop situations) and weather-damaged seed...
