* Disseminate results through scientific publications, technical reports and presentations to stakeholders and the agricultural sector
This makes you unique
* Master's degree in plant pathology, plant protection, agronomy, entomology, plant sciences or a related discipline
* Strong interest in plant virology, agroecology and sustainable crop protection
* Experience in field experimentation, data analysis or laboratory techniques (e.g. ELISA, PCR) is an advantage

In a nutshell
This PhD position is part of the ViKaan project (Viren im Kartoffelanbau / Les virus dans la culture de la pomme de terre), which aims to develop integrated strategies to control the spread of Potato virus Y (PVY) and Potato leafroll virus (PLRV) in Swiss seed potato production.
The project investigates varietal susceptibility to viruses, evaluates agroecological approaches to increase biodiversity (such as companion plants), and tests innovative vector management strategies including straw mulching and oil applications. The project also integrates economic analyses to identify strategies that are both effective and economically viable for farmers.
The ultimate goal is to strengthen the resilience and sustainability of Swiss seed potato production under increasing virus pressure and climate change.
The project is funded by the Swiss Federal Office for Agriculture (FOAG).

Additional Information
The 'Cultivation Techniques and Varieties in Arable Farming' Research Group is dedicated to researching sustainable production techniques and new climate-change-adapted varieties for the main field-crop species cultivated according to various production techniques (integrated production, quality labels or organic farming). To accomplish its mission, it is active in testing, mainly in the field, from Lake Geneva to East Switzerland.
