Leaf spot of strawberry, caused by various fungal pathogens such as Mycosphaerella fragariae and Diplocarpon earlianum, manifests as dark lesions on the leaves. These lesions may start small but can expand, leading to significant leaf damage. Warm and moist conditions favor disease development. Management typically involves cultural practices like sanitation, proper spacing, and fungicide applications to prevent spread and minimize damage, ultimately preserving the health and productivity of strawberry plants.
