Diseases like potato late blight (Phytophthora infestans) are among the major constraints that limit potato production.Climate changes have a strong impact both on the destructive potential of diseases and on the environment. A field investigation was conducted during 2023-2024 to National Institute of Research and Development for Potato and Sugar Beet Brasov. Twelve potato Romanian varieties and a fungicidal program were used. Data on first disease symptom appearance, disease incidence, and disease progress rate were recorded. The impact on the obtained yield was also analyzed. Generally, late blight severity in 2024 was greater than it was in 2023 as several varieties (Darilena and Marvis) reached high severity in both years. Furthermore, to other varieties late blight was absent (Cosiana and Asinaria in 2023) or its severity was less than 1% for the entire duration of the epidemic (Sarmis in 2023 and Asinaria in 2024).
