Abstract
After almost two centuries since the infamous Irish Potato Famine, potato late blight, caused by the oomycete Phytophthora infestans, continues to be the most economically destructive potato disease globally, resulting in annual losses surpassing 10 billion USD. Considerable advancements have been made over several decades in comprehending the molecular mechanisms behind the pathogenicity of P. infestans and devising efficient ways for its management. However, in order to guarantee food security for an expanding global population in the face of a changing environment, it is imperative to make more progress in developing effective, sustainable, and economically flexible strategies to control potato late blight. This work delves into the complex nature of P. infestans, reviews the effectiveness of current integrated pest management strategies, and analyzes the potential of innovative sustainable ways for controlling the disease.
