Fig trees are generally hardy and resilient, but they are not immune to diseases. Recognizing the symptoms of common fig tree diseases can help you prevent and treat these problems, ensuring a healthy and productive tree. In this article, we’ll cover the most common diseases that affect fig trees and provide tips on how to manage them.

1. Anthracnose
Anthracnose is a common fungal disease that affects fig trees, causing dark, sunken lesions on leaves, fruit, and stems. The disease thrives in warm, humid conditions and can cause significant damage if left untreated. To manage anthracnose, prune and remove infected parts of the tree, avoid overhead watering, and apply a copper-based fungicide.
2. Fig Rust
Fig rust is another fungal disease that affects fig trees, primarily targeting the leaves. Infected leaves develop yellow spots that eventually turn brown and fall off. This disease is most common in late summer and fall. To control fig rust, remove and destroy infected leaves, improve air circulation around the tree, and apply a suitable fungicide.
3. Fig Mosaic Virus
Fig mosaic virus is a viral disease that causes mottled or mosaic patterns on the leaves of fig trees. The disease can also affect the fruit, leading to distorted or stunted growth. There is no cure for fig mosaic virus, but you can manage the disease by pruning and destroying infected branches, controlling insect vectors, and planting resistant fig tree varieties.
4. Crown Gall
Crown gall is a bacterial disease that causes swollen, wart-like galls to form on the roots and stems of fig trees. The disease can weaken the tree and inhibit growth. To prevent crown gall, avoid injuring the tree during planting or pruning, and remove and destroy any infected plants or plant parts. Using disease-free planting material is also crucial for prevention.
5. Root Knot Nematodes
Root knot nematodes are microscopic worms that infect the roots of fig trees, causing galls or knots to form. This can lead to stunted growth, yellowing leaves, and reduced fruit production. To manage root knot nematodes, plant resistant fig tree varieties, solarize the soil before planting, and practice crop rotation.
Fig trees can face various diseases, but with proper care and attention, you can keep your fig tree healthy and productive. By recognizing the symptoms of common fig tree diseases and implementing appropriate management strategies, you can ensure a bountiful harvest for years to come.
