Common Fig Plant Diseases:
How to Identify and Treat

Updated: May 16, 2022

The fig plant, also known as Ficus carica, is a fruit-bearing tree that belongs to the mulberry family. This plant is native to the Middle East and has been cultivated for thousands of years for its sweet and juicy fruits. However, like any other plant, figs are susceptible to various diseases that can affect their growth and yield. In this article, we will discuss some of the most common fig plant diseases, their symptoms, and how to treat them.

1. Fig Rust

Fig rust is a fungal disease that affects the leaves of the fig tree. It is caused by the fungus Physopella fici and can cause significant damage if not treated promptly. The symptoms of fig rust include yellow spots on the leaves that eventually turn brown and fall off. If left untreated, the disease can weaken the tree and reduce its fruit production.

To treat fig rust, remove all infected leaves and dispose of them. Avoid wetting the leaves when watering the tree and apply a fungicide spray containing copper sulfate or sulfur to prevent further infection.

2. Fig Mosaic Virus

The fig mosaic virus is a viral disease that affects the leaves of the fig tree. It is spread by sap-sucking insects such as aphids and whiteflies. The symptoms of fig mosaic virus include yellow mottling or streaking on the leaves, which can eventually lead to leaf distortion and stunted growth.

Unfortunately, there is no cure for fig mosaic virus once a tree is infected. The best course of action is to remove and destroy any infected plants to prevent further spread of the disease. To prevent infection, use insecticides to control sap-sucking insects and avoid planting new trees near infected ones.

3. Root Knot Nematodes

Root knot nematodes are microscopic worms that attack the roots of fig trees. They cause root galls, which are swollen areas on the roots that can disrupt the tree’s ability to absorb water and nutrients. The symptoms of root knot nematodes include stunted growth, yellowing leaves, and reduced fruit production.

To treat root knot nematodes, apply a soil fumigant or nematicide to the affected area. You can also plant nematode-resistant varieties of fig trees or rotate crops to reduce the nematode population in the soil.

4. Fig Anthracnose

Fig anthracnose is a fungal disease that affects the fruits of the fig tree. It is caused by the fungus Colletotrichum gloeosporioides and can cause the fruit to rot and become discolored. The symptoms of fig anthracnose include sunken spots on the fruit that eventually turn black and dry.

To treat fig anthracnose, remove any infected fruit and dispose of them. Apply a fungicide spray containing copper sulfate or sulfur to prevent further infection.
