RustWatch: A European early-warning system for wheat rust diseases

Deliverables

Access to wheat variety deployment at county, national and European scale through the Wheat Rust Toolbox

Statistics on wheat the deployment of registered varieties over the last decade will be collected at the European scale. These data will be accessible through the Wheat Rust Toolbox, allowing to visualize varieties’ acreages and temporal evolution on maps and graphs.

Annual report (2019) and press release about race typing and genotyping of Pst, Pt and Pgt (T1.1)

Annual reports about 2018, 2019, 2020 and 2021changes in P. striiformis, P. triticina and P. graminis populations in Europe. The reports will highlight changes of relevance for rust susceptibility of wheat varieties and breeding lines of agronomic importance. The underlying data feeding into the reports will be imported from the online resources in RustWatch, e.g., the WheatRustToolbox

Evaluation of deployment of wheat rust differential lines for improved VCU testing and pathogen monitoring

The procedures for assessment of rust diseases in VCU trials will be updated by improved state-of-the-art methodologies. The usefulness for deployment of Pst wheat differential lines to assist early-warning of new races will be evaluated in collaboration with WP1.

RustWatch mobile App for reporting and dissemination of wheat rust disease data. Documentation and user guide

A documentation and user guide will describe the RustWatch mobile Apps for reporting and dissemination of wheat rust disease data. The use of mobile applications aim at increasing the quality and amount of data collected in fields and trials as well as facilitating fast and effective alerts and information of early warning information.

Capacity for sexual reproduction of prevalent races of Pst in Europe identified (T1.3)

Investigation of sexual capacity of present and new races of P. striiformis in Europe will contribute to evaluating the risks of yellow rust sexual reproduction on the alternate host, Berberis vulgaris in Europe.

Web service for exchange of surveillance data between RustWatch and existing surveillance systems in case study regions. Technical note

A technical note will describe web services developed for the automatically exchange of surveillance data between RustWatch and existing surveillance systems in case study regions.

Assessment of rust control in coordinated IPM trials in up to 10 regions -2019.

M21- In series of field trials, new IPM strategies will be investigated by using cultivation practices, rust resistant varieties, control thresholds, synthetic fungicides and bio-pesticides. The results will be reported each year after the trials have been completed and appropriate analyses of results have been made, allowing adjustments in recommendations for wheat rust control by end-user farmers.

Web based Trap Nursery Data Management, analysis and display system. Documentation and user guide

A documentation and user guide will be developed for the web based Trap Nursery Data Management, analysis and display system. Output from this system will be used to evaluate results of the VCU trials and as input to the early warnings system.

Assessment of rust control in coordinated IPM trials in up to 10 regions -2020.

M33- In series of field trials, new IPM strategies will be investigated by using cultivation practices, rust resistant varieties, control thresholds, synthetic fungicides and bio-pesticides. The results will be reported each year after the trials have been completed and appropriate analyses of results have been made, allowing adjustments in recommendations for wheat rust control by end-user farmers.

Management, analysis and display of data in RustWatch utilising the Wheat Rust Toolbox. Documentation and user guide

A documentation and user guide for proper use of the Wheatrust Toolbox will be developed. This will facilitate effective storage, analysis and dissemination of data and information from the project via database driven information systems, web tools and mobile platforms. The WheatRust Toolbox will be the “control centre” of the Wheat Rust early warnig system.

Annual report (2018), and press release about race typing and genotyping of Pst, Pt and Pgt (T1.1)

Annual reports about 2018 changes in P. striiformis, P. triticina and P. graminis populations in Europe. The reports will highlight changes of relevance for rust susceptibility of wheat varieties and breeding lines of agronomic importance. The underlying data feeding into the reports will be imported from the online resources in RustWatch, e.g., the WheatRustToolbox

Annual report (2020), and press release about race typing and genotyping of Pst, Pt and Pgt (T1.1)

Annual report 2020 about changes in P. striiformis, P. triticina and P. graminis populations in Europe. The report will highlight changes of relevance for rust susceptibility of wheat varieties and breeding lines of agronomic importance. The underlying data feeding into the reports will be imported from the online resources in RustWatch, e.g., the WheatRustToolbox.

Recommendations for coordinated and harmonized wheat rust surveillance in Europe based on input from stakeholders

This deliverable will identify the most relevant data and protocols from national surveillance activities and recommend coordinated wheat rust surveillance activities in Europe based on input from stakeholders in five case study regions.

First set of practice abstracts

A compilation of first set of practice abstracts uploaded to the EIP-AGRI website for broad dissemination. A roadmap for producing the practice abstracts will be developed and published in D4.2

Evaluation of off-season testing early detection of susceptibility of wheat lines to new races of yellow and Pt

After two years of early detection of susceptible varieties/lines to emerging rust races, the the reliability and interest of the information provided on the varieties by off-season testing will be evaluated by the involved partners.
