The study analyzes the impact of climatic conditions on the dynamics of diseases and pests in cabbage crop at the Vegetable Research and Development Station Bacău. High temperatures, with a maximum of 35.5°C in mid-summer, favored the development of pests such as Phyllotreta spp. and Plutella xylostella, while the August drought (rainfall of 0.3 mm) increased infestation. In contrast, high humidity in May-June supported the emergence of Brevicoryne brassicae, while heavy rainfall in September (170.4 mm) intensified the spread of fungal diseases, including Xanthomonas campestris. The analysis correlates variations in temperature, humidity and rainfall with the specific dynamics of the main pest species, highlighting the major challenges for phytosanitary control of cabbage crops in the context of climate change. The results provide a basis for improving integrated management strategies adapted to extreme and diversified weather conditions. The study underlines the importance of agro-meteorological monitoring in optimizing crop protection.
