Common Plant Diseases
1. Powdery Mildew
Powdery mildew is a fungal disease that affects various plants, including vegetables, fruits, and ornamental plants. It presents itself as powdery, white or gray spots on the leaves, stems, and flowers. This disease thrives in warm, humid weather conditions and can spread rapidly, reducing the plant’s photosynthesis and causing stunted growth.
Treatment: Remove affected leaves and spray the plant with fungicide. For prevention, maintain good air circulation, avoid watering in the evening, and remove any diseased plant debris.
2. Black Spot
Black Spot is a common disease that affects rose bushes. It presents as circular black spots on the leaves, causing them to turn yellow and fall off. This fungal disease thrives in warm, humid weather conditions and spreads rapidly, defoliating the plant.
Treatment: Remove affected leaves and spray the plant with a fungicide. Prune the rose bush to promote air circulation, keep the soil moist but not waterlogged, and avoid overhead irrigation.
3. Tomato Blight
Tomato blight is a fungal disease that affects the leaves, stems, and fruits of tomato plants. It presents as brown spots on the leaves, causing them to wilt and eventually die. This disease thrives in warm, humid weather conditions and can spread rapidly, causing tomato crops to fail.
Treatment: Remove affected leaves and spray the plant with fungicide. Practice crop rotation and avoid overhead irrigation, which can spread the spores.
4. Root Rot
Root rot is a fungal disease that affects the roots of many different plants. It can cause the plant to wilt, turn yellow, and eventually die. The fungus thrives in waterlogged soil conditions and can spread rapidly.
Treatment: Remove affected plants and improve soil drainage. Avoid overwatering and use fungicide-treated seedlings.
