Phytophthora fragariae is a malicious infection that can cause red patches on strawberry leaves. Signs and symptoms include rotting of stem, leaves, and fruit. The fungus thrives in wet soil and poor drainage conditions, especially in warm temperatures. Overcrowding plants, over-watering, and low-quality soil can increase the risk of infection.

To prevent phytophthora fragariae, biological control measures like using disease-resistant varieties, planting in well-draining soil, and avoiding over-watering need to be adopted. Fungicides such as copper-based compounds can also be used. Timely inspection and removal of infected plants are crucial to prevent the spread of infection to other plants.
