Common Pomegranate Pests
Common pests affecting pomegranate trees include:
- Aphids: Small, soft-bodied insects that feed on sap.
- Whiteflies: Small, white insects that cluster on the undersides of leaves.
- Scales: Tiny, immobile pests that attach themselves to branches and leaves.

Pomegranate Pest Control
Natural Predators Encourage natural predators such as ladybugs, lacewings, and parasitic wasps. These beneficial insects help control pest populations naturally.
Neem Oil Spray Use neem oil spray as a natural and effective insecticide. Neem oil disrupts the life cycle of many pests and acts as a repellent. Apply it according to the package instructions, especially during the growing season.
Horticultural Oils Horticultural oils can smother and kill pests. Apply these oils to your pomegranate tree following the manufacturer’s recommendations, especially during the dormant season.
Insecticidal Soaps Insecticidal soaps are effective against soft-bodied pests like aphids. Follow the instructions on the product label for safe and proper application.
Common Pomegranate Diseases
- Powdery Mildew: A white powdery substance on leaves and fruit.
- Leaf Spot: Circular lesions with a dark border on leaves.
Pomegranate Disease Control
Clean Pruning Practice clean pruning by removing dead or infected branches. This helps prevent the spread of diseases and improves air circulation within the tree.
Proper Watering Avoid overwatering, as excessively moist conditions can lead to fungal diseases. Water at the base of the tree, keeping the foliage dry.
Fungicide Applications Apply fungicides preventively during periods of high humidity or when disease pressure is prevalent. Common fungal diseases affecting pomegranate trees include:
Cultural Practices Practice good cultural habits, such as proper spacing between trees to improve air circulation, and regularly cleaning up fallen leaves and debris.
Regular Monitoring Monitor your pomegranate tree regularly for early signs of diseases. Promptly address any issues to prevent the spread and escalation of problems.
Integrated Pest Management (IPM): Implement Integrated Pest Management strategies, combining cultural, biological, and chemical control methods. This holistic approach minimizes the environmental impact while effectively managing pests and diseases.
