Net blotches (Pyrenophora teres f. teres and P.t. f. maculata) remain the major diseases of barley in the northern region... While net form net blotch (P.t. f. teres) can be the more devastating disease, resistance to the disease is present in several of our leading varieties... Seed harvested from crops heavily infected with net form net blotch should not be retained for sowing...

Buloke maintained its popularity in 2012, with a large increase in the popularity of Hindmarsh and a large decrease in the popularity of Baudin and Vlamingh... Hindmarsh is a very good variety and is the best alternative to malting varieties in environments where the yield potential is below 2.5 t/ha and/or there is a low expectation of delivering malt grade barley... Overall, the big winner was Hindmarsh, increasing in acreage by nearly 120,000 ha in 2012 and pipping both Gairdner and Vlamingh in total acreage...

Variation in NFNB is on the increase and making resistance ratings for varieties more complicated... After the demise of Skiff in 1999 only low levels of the disease were observed in barley crops, mainly on Barque on the lower Yorke Peninsula, and apparently only one pathotype was present... The differences within the rust population go unnoticed in annual surveys conducted by the University of Sydney but can lead to very significant differences in crop damage...

Dr Kith Jayasena, GRDC supported plant pathologist with DAFWA at Albany, has urged WA growers to be vigilant in checking barley crops for barley leaf rust and adopt a 'no-nonsense' approach if found... He said barley leaf rust had been found in two South Stirling commercial crops and growers finding the pin-sized orange rust pustules on barley leaves would have to spray to protect their crops, as most varieties are susceptible. ".. Dr Jayasena advises growers to have suspected rust checked for free by DAFWA at AGWEST Plant Laboratories (Tel 9368 3721)...

Monitoring of all Western Australian barley crops for powdery mildew disease and careful fungicidal management including the use of seed dressings will reduce the risk of yield losses this season, with commonly grown varieties found to have an increased susceptibility to the disease... Recent rainfall could favour the development of powdery mildew, which has already been observed in barley regrowth at a number of sites across barley growing regions in WA's central and southern grain growing regions... Photo Caption: GRDC-supported research conducted by the ACNFP has found that commonly grown barley varieties have an increased susceptibility to the disease...

The checklist gives growers a comprehensive 'to do list' that will help growers maximise the potential that each year offers so they will be satisfied when harvest rolls around and yield and protein levels come in... Rotations - top of the list is the selection of crops and varieties as rotations, summer and winter, have become essential to our farming system in terms of controlling weeds and diseases...

2010 provided the most favourable conditions for the development of foliar diseases for 12 years which generated epidemics of yellow spot in wheat and spot form net blotch and leaf rust in barley... It is essential that an integrated approach of cultural, genetic and chemical methods is implemented to maximize control and minimize losses... To minimize inoculum, there should be no green barley plants growing in the region for 4 to 6 weeks before sowing - the longer, the better...

Crop disease management in water limited environments A feature of cropping enterprises in the water limited environments of the northern and central agricultural regions of WA is the intensive cereal rotations used to maintain profitability and manage weeds... The project will develop disease management recommendations for intensive cereal rotations to enable growers to minimise the impact of foliar and root diseases on cereal yields... Maintaining market access Changes to the World Trade Organisation legislation now require that countries participating in international trade, such as Australia, must prove that specific grain pests and diseases exotic to importing countries are known not to occur in the exporting country...
