Integrated management strategies are described for barley foliar diseases. Several Australian barley cultivars already contain adult plant resistance provided by the Rph20 gene. The incidence, severity and yield loss caused by 40 pathogens associated with 41 diseases of barley were assessed from a survey of 15 barley pathologists covering the winter cereal growing areas of Australia. Barley growers are advised to monitor their crops for early signs of fungicide resistance, with research uncovering new developments in the resistance to fungicides in a common barley disease of the southern cropping region. Fungicides should be used as protectant treatments – where there is no more than 5% leaf area infection evident anywhere in the canopy. The Government of Western Australia acknowledges the traditional custodians throughout Western Australia and their continuing connection to the land, waters and community. Australian researchers have confirmed a new form of dual fungicide resistance in the common barley disease, net form net blotch (NFNB). For autumn or winter planted barley crops there is usually sufficient to warrant a GS30 application. Source: Australasian plant pathology 2010 v.39 no.1 pp. They kill off the disease spores and prevent further infection. As relations soured this year after Canberra proposed an independent investigation into the origins of the […] Disease symptoms Severe seedling infection can cause stunting and post-emergence death, but symptoms are not usually apparent until later, when long, chlorotic or yellow stripes on leaves and sheaths appear. Barley Australia delivers leadership to increase the value and enhance the sustainability of Australia’s barley industry. The Russian wheat aphid’s host range also includes several non-crop grass species that occur in Australia. Stubble-borne fungal diseases spot net type blotch and net type net blotch have been discovered on several farms across the region, and barley scald and barley powdery mildew also started to appear on some properties. It is important that plans are developed to effectively manage wheat and barley diseases this season. Acknowledging the appeal take years to be resolved, Birmingham told reporters Australia would also request formal consultations with China regarding dumping and other duties on Australian barley amid an increasingly bitter trade and diplomatic row between the two countries. Foliar diseases such as scald, net blotches (net-type and spot-type), powdery mildew and leaf rust can reduce yield and grain quality. Barley is most commonly used for heart disease and high cholesterol. "If these diseases are appearing in crops now a foliar fungicides can be applied to control them," he said. Brown rust is world-wide distribution. • Vigorous plant growth and high water use They have identified a new genotype in NFNB that is – for the first time known – showing dual resistance to both a succinate dehydrogenase inhibitor (SDHI) fungicide as well as some DeMethylation Inhibitor (DMI) fungicides. We will achieve this by addressing the following key activities: Providing timely and credible industry-specific information; Managing the malting barley accreditation process The spot form is more common in Victoria, due to the widespread cultivation of susceptible varieties. Again for most barley crops to not treat for RLS at GS39 would be a brave decision. Mr Jayasena said one weapon in growers' arsenal was the use of fungicides. Barley growers across the southern region should remain vigilant when it comes to monitoring their crops for foliar diseases this season, especially if new varieties have been sown. Inoculum levels will be higher than normal for cereal diseases in the 2017 season following high disease levels during 2016. The next generation, potential malting, IMI Gladiator ... A high yielding APW with robust disease resistance, providing a diverse early-mid flowering alternative. Agrobase Australia. The aim of this guide is to enable barley growers to identify where production may be falling short of potential. In most parts of Victoria leaf rust is effectively controlled with resistant varieties. Maximus CL . Barley stripe is disease of barley. Would infect barley in all Australian growing regions; Approximately 80% of Australia’s barley varieties would be susceptible; Yellow stripes of fungal spores produced between veins of leaves; Can be spread by wind and rain, or on clothing, machinery and tools; Any stripe rust on barley should be reported Advantages include: • Less susceptible to frost than wheat. 2 Diseases are just one factor that may produce spots and other symptoms on barley. Barley yellow dwarf (BYD) is a plant disease caused by the barley yellow dwarf virus (BYDV), and is the most widely distributed viral disease of cereals. What is the Ramularia leaf spot (RLS) threat. They have identified a new genotype in NFNB that is – for the first time known – showing dual resistance to both a succinate dehydrogenase inhibitor (SDHI) fungicide as well as some DeMethylation Inhibitor (DMI) fungicides. This leads to yellowing of the plant, stunted growth and loss of vigour. Rhynchosporium secalis. "Also if barley is going on barley or next to a barley crop from last year, then it is a high risk situation and needs to be managed." Barley leaf scald. Useful resources. Barley leaf disease management options supported by the latest research findings are shown here. Barley is rich in phytochemicals, including lignans, phenolic acids, phytic acid, plant sterols and saponins, which "act as antioxidants to help protect against disease". It affects the economically important crop species barley, oats, wheat, maize, triticale and rice Biology. The disease rarely exceeds 3% leaf area affected, but severe disease epidemics can occur in individual crops where yield losses of 30% have been reported. What is the disease pressure in my crop at the end of winter? Market leading barley varieties for Australia including feed and malting barley varieties suited to all Australian barley growing regions. Examples of these barley varieties include Flagship, Oxford, Shepherd and Westminster. Estimating disease losses to the Australian barley industry Author: Murray, G.M., Brennan, J.P. Beijing this year slapped anti-dumping and anti-subsidy duties to the tune of 80.5% against Australian barley. Symptoms, disease cycle, management of rusts of barley including leaf rust and stem rust. In fact, NFNB can reduce barley yields by up to 70 per cent due to the fungus penetrating the plant stem, blocking nutrient transfer and causing collapse of the plants. Cereal diseases will need proactive management during 2020 as there will be high levels of stubble-borne inoculum following limited breakdown over the summer. The dry conditions during early summer will reduce the risk posed by rust and aphid spread viruses due to the limited green bridge, however, this may change if rainfall events continue in the lead up to sowing. Barley growers in the Great Southern are being warned that several diseases have started appearing in crops in the region in the past month. Ramularia leaf spot of barley, a disease caused by the fungus Ramularia collo-cygni, was first detected in December 2016 at a barley trial site near Hagley in northern Tasmania. • Quicker to maturity than wheat. Rusts are the most important foliar diseases of wheat in Australia.

In the decade to 2009, this loss represented 19.5% of the average annual value of the barley crop. In high risk disease environments, integrated management approaches should be used to reduce fungicide resistance risk, which may include: removal of stubble, crop rotation (avoid barley on barley), Disease susceptibility factors often control host immune responses. Diseases Barley diseases cause an estimated current average annual loss of AU$252 million, or $66.49 per hectare, to the Australian barley industry. Barley – planting and disease guide 2014 Queensland and NNSW Barley - advantages Barley is a crop which fits well into the northern farming systems as a winter cereal crop. Stripe rust.
