The Case study approach will allow us to investigate the threats of invasive rust races at the regional scale and suggest IPM-based prevention and control options adjusted to the relevant agronomical practices and environmental conditions in the considered region.

• The project will facilitate the establishment or further develop existing stakeholder networks, enabling access to shared facilities and validating the new early-warning system in Case study regions.

• The early-warning system and recommendations will be validated in the five Case study regions selected to represent different agro-ecological features with respect to the climate and to the average usage of fungicides.

• Each case study region will host at least one IPM trial and engage stakeholder groups in workshops, and feed-back from these end-users will help to develop and adjust the proposed early-warning system.

• Pre-existing stakeholder networks and services within plant breeding, agrochemical industry, extension services and VCU approval in cereals will be used to assist rust surveillance and sampling in the case study regions.

• Hands-on workshops and training in disease assessment, sampling, analysis and use of tools and services generated in the project will also be organized in the context of Case study regions.

• Specific tasks and key persons will be allocated for communication with the non-partner companies and organizations within the stakeholder networks and allow unusual rust disease patterns at any time and location to be recorded and samples to be collected and diagnosed. This will ensure the implementation of new solutions for prevention and control of rust diseases beyond project partner organizations and companies, reflecting a true multi-actor approach.

• Regional Stakeholder workshops and open field days will facilitate a multiactor approach and effective exploitation of results
