Common Pepper Diseases and How to Identify Them
This section highlights prevalent diseases affecting peppers, their symptoms, causes, and recommended actions. Visual identification is key, and the information provided can be cross-referenced with images typically included in a detailed pepper diseases identification pdf.
1. Anthracnose (Colletotrichum spp.)
Symptoms:
- Sunken, dark, and water-soaked lesions on fruits
- Circular, tan to dark brown spots with irregular margins
- Severe infections cause fruit cracking and rot
Causes:
- Fungal pathogen thrives in warm, humid conditions
- Poor sanitation and excessive moisture promote spread
Management:
- Use disease-free seeds and resistant varieties
- Apply appropriate fungicides as recommended
- Improve air circulation and avoid overhead watering
- Remove and destroy infected plant debris
2. Bacterial Spot (Xanthomonas campestris pv. vesicatoria)
Symptoms:
- Small, dark, greasy spots on leaves
- Yellow halos around lesions
- Defoliation and reduced fruit quality
Causes:
- Bacterial pathogen spread through splashing water and contaminated tools
- High humidity and warm temperatures favor infection
Management:
- Use disease-free seedlings
- Practice crop rotation and sanitation
- Apply copper-based bactericides
- Avoid working with plants when foliage is wet
3. Powdery Mildew (Leveillula taurica)
Symptoms:
- White, powdery fungal growth on leaf surfaces
- Leaf yellowing and curling
- Reduced photosynthesis leading to stunted growth
Causes:
- Fungal spores spread by wind and insects
- Favorable conditions include moderate humidity and moderate temperatures
Management:
- Improve air circulation and spacing
- Apply sulfur or biological fungicides
- Remove infected plant parts
- Use resistant cultivars if available
4. Phytophthora Blight (Phytophthora capsici)
Symptoms:
- Wilting and yellowing of plants
- Dark, water-soaked lesions on stems and roots
- Fruit rot with foul smell
Causes:
- Soil-borne oomycete pathogen
- Excessive watering and poor drainage increase risk
Management:
- Ensure well-drained soils
- Rotate crops with non-host plants
- Apply appropriate fungicides
- Remove and destroy infected plants
5. Mosaic Virus Diseases
Symptoms:
- Mottled, mosaic-like patterns on leaves
- Leaf distortion and stunted growth
- Reduced fruit set and quality
Causes:
- Spread by aphids and other insects
- Contaminated tools and infected plant material
Management:
- Control insect vectors
- Use virus-free seeds and resistant varieties
- Remove infected plants promptly
- Practice crop rotation and sanitation
