One or more species of RLN (Root Lesion Nematode, Pratylenchus spp.) occur in at least 60% of WA cropping paddocks... P. thornei occurs rarely; P. neglectus is the most frequent RLN identified in WA, occurring in at least 40% of paddocks; P. teres is found in 10% of paddocks... It is imperative that the species of RLN is correctly identified to enable growers to deploy appropriate crop varieties and species to minimise current and future losses...

One or more species of RLN (Root Lesion Nematode, Pratylenchus spp.) occur in at least 60% of WA cropping paddocks... The principal outputs of this project will be knowledge of wheat varieties which are more resistant to RLN (i.e. limit the multiplication of RLN under a crop) & more tolerant to RLN (i.e. yield loss incurred in a variety due to RLN is minimised)... RLN research in WA will continue to focus on management, principally through rotational recommendations for the deployment of cereal cultivars (& other host crops) with a level of resistance to each RLN that will benefit subsequent crop yields...

Sustainable management of most cereal diseases can be achieved by avoiding susceptible and very susceptible cultivars... A graphical representation of the relative effect of increasing pre-sowing crown rot inoculum levels, as determined using PredictaB, on grain yield loss (%) in three cereals in seasons with below average combined September and October rainfall (left) and above average rainfall for the same period (right) using 26 data sets collected in Victoria and South Australia during the years 2005 to 2010 (Hollaway et al. 2013)... There will be a greater need to monitor and apply foliar fungicides in wetter seasons...

x Make use of available testing services to determine nematode species and levels, but be aware that PreDicta-B cannot currently detect some of the nematodes present in WA crops... Crop Updates is a partnership between the Department of Agriculture, Western Australia and the Grains Research & Development Corporation 72.. Overall, lupin was resistant, but Mandelup and Belara resulted in a nematode multiplication rate > 1...

" Rotations to reduce impact of nematodes in Western cereal cropping systems DAW00124 Start Date: 01/07/2005.. Results for Pratylenchus penetrans indicate that RLN could possibly adapt to different hosts, depending on cropping history... To optimise the management of RLN with the use of rotations, these weeds should be controlled in cropping paddocks...

Thirteen developmental and commercially available seed applied fungicides were evaluated in the glasshouse and the field for their potential use in reducing SFNB severity... Four commercially available barley cultivars (Barque ,A Cowabbie, Schooner ,A VB9104) known to possess either complete, seedling or adult resistance to SFNB were evaluated in the field... In the glasshouse seedlings from the DPN (wheat), EBDSN (barley) and/or NVT (wheat and barley) lines were evaluated for reaction to yellow leaf spot (wheat) and spot and net forms of net blotch (barley)...

In many cropping soils of south-eastern Australia the presence of nematodes limits field crop production... Recent reports by Murray and Brennan (2009 a & b) estimated that in south-eastern Australia alone, nematodes are currently reducing wheat and barley production by 4.9% ($98 million) and 5.1% ($42 million) respectively, with losses in excess of 20% possible in the absence of appropriate control strategies... Growers can minimise yield loss caused by the nematodes in two ways...
