At a trial site near Yallaroi in 2012, a range of crops and varieties were grown where performance was evaluated in strips with contrasting starting levels of Pt ... All varieties evaluated in all 9 trials except CICA0912 (only 6 trials).. Differences in Pt populations following a range of crops assessed at two sampling times during the fallow, Yallaroi 2012..

By screening and field testing the resistance and tolerance of wheat and barley cultivars, relevant information can be supplied to allow growers to incorporate cultivars into rotations that limit the populations of and damage caused by nematodes... Significant yield impacts occurred for wheat varieties assessed in Toodyay 2012 when comparing yield to nematode numbers at anthesis (Table 2)... Coupled with resistance data, these results indicate Emu Rock may be only moderately susceptible but very intolerant to P. teres while the other varieties are intolerant but range in levels of susceptibility to the pest...

" Pratylenchus teres- WA's home grown Root Lesion Nematode (RLN) and its unique impacts on broadacre crops.. By screening and field testing the resistance and tolerance of wheat and barley cultivars, relevant information can be supplied to allow growers to incorporate cultivars into rotations that limit the populations of and damage caused by nematodes...

Key Points Research into biological control of the costly root-lesion nematode could boost yields and reduce losses... The GRDC-funded research is exploring the potential of naturally-occurring soil organisms to suppress RLN... Dr Seymour says the research will result in the identification of the key organisms involved in the suppression of RLN in northern grain-growing soils and an understanding of soil chemical, physical and biological characteristics associated with suppressiveness...

Tests will confirm species and population levels of these microscopic endoparasites and help the Department of Agriculture and Food WA (DAFWA) characterise distribution and gather resistance information for crops and varieties grown in WA... The research, jointly funded by GRDC and DAFWA, is vital because yield loss can occur without careful planning in crop variety selection and no chemicals are currently available to economically control RLN in broadacre cropping systems... Using resistant varieties of a crop to inhibit nematode reproduction...

Know your nematodes and set up a crop defence system in 2014.. WA growers are encouraged to find out what species and levels of root lesion nematodes (RLN) are present in their soils during the growing season... DAFWA research has indicated crops that are resistant to P. penetrans are often highly susceptible to P. neglectus or P. teres, highlighting the importance of knowing which species of RLN is present - as management of one RLN species may be causing an increase in another...

Boosting the suppressiveness of soils to RLN is emerging as a new frontline defence in controlling and eventually reducing RLN populations when used in conjunction with a best practice integrated management program... The challenge for industry lies in gaining a better understanding of the suppressive nature of grain-growing soils within the northern region with the aim of providing growers with methods to enhance the suppressiveness of their soils to RLNs... The impact of farm practices on the suppressiveness of soils to RLNs was studied as part of the project with results showing that factors such as pastures in rotation had a limited impact on soil suppressiveness...

Growers do not have access to varieties with resistance to the key exotic pests and disease... The project will proceed in two phases... The project is about optimizing pesticide sprayapplications by: identifying spray technologies and spray settings with low risk of spraydrift, applying pesticides in accordance with latest knowledge about pest behaviour in response to pesticides andtherefore minimizes the risk of target pests developing resistance, and by using pesticides with documented efficacyagainst target pests...

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...
