Technical Session D: Potato Pest and Diseases

 

Chair: John Jamieson – Prince Edward Island, Canada | Deputy Minister of Agriculture and Fisheries

Chair: Jonathan Jones –  Professor | The Sainsbury Laboratory UK

Co-chair: Jan Kreuze – Leader, Crop Protection Division | International Potato Center

Tuesday 29 May – 10.30 – 14.50 hrs

Summary:

Pests and diseases are among major constraints to potato production worldwide. Global trade is already signifi cantly exacerbating the spread and impact of pest and diseases worldwide, but changing climates will further alter and contribute to the emergence of new pest and disease threats as well as to increased infestations and yield losses This technical session will address signifi cance of climate change highlighting advances and new approaches in all aspects of potato pest and disease management including monitoring, diagnostics, advanced predictions of risks through modeling, population dynamics and epidemiology, decision support systems and integrated pest and disease management.
