In summer, plants often face several diseases because of the heat, humidity, and increased insect activity. Some common plant diseases in summer include:
 |
1. Powdery Mildew
White, powdery spots on leaves and stems.
Thrives in warm, dry days and humid nights.
2. Leaf Spot Diseases
Brown, black, or yellow spots on leaves.
Caused by bacteria or fungi, common in hot and humid conditions.
3. Downy Mildew
Yellow patches on the upper side of leaves and fuzzy growth underneath.
Loves humid, cooler nights.
4. Blight (Early and Late)
Rapid browning and death of leaves and stems.
Especially affects tomatoes and potatoes in hot, wet weather.
5. Root Rot
Wilting despite watering, yellow leaves, and stunted growth.
Caused by overly wet soil and fungal infections.
6. Anthracnose
Dark, sunken lesions on leaves, stems, fruits.
Fungi spread in warm, wet weather.
7. Rusts
Orange, brown, or red pustules on leaves.
Hot, moist environments make rust spread quickly.
8. Verticillium Wilt
Wilting and yellowing starting from older leaves.
Caused by soil-borne fungi, more active in summer.
