Warming temperatures are reshaping the global risk map for potato diseases, writes Lukei Pieterse in this article. Late blight, PVY, blackleg, zebra chip, and bacterial wilt are expanding into new regions, driven by shifting climates, vector dynamics, and environmental stress. The impacts extend from field to storage, undermining yield, seed quality, and marketability. This article explores emerging threats, affected regions, and the urgent need for adaptive strategies across breeding, forecasting, and integrated disease management.
