Figs are considered hardy trees with relatively few disease or pest issues. They do have specific diseases to which they are susceptible. Knowing the types of diseases, damage and control methods will help with fig tree cultivation.
Fig trees are thought to be native to Western Asia. They produce the best quality fruit in warm temperate climates. They can also grow in wetter, cooler climates with extra care. Tropical climates propagate diseases limiting the trees utility.
Fig trees are susceptible to anthracnose, fig rust, fig mosaic, endosepsis rot and aspergillus rot. Most losses of ripe fruit are attributed to endosepsis and aspergillus rot.
When uncontrolled, the diseases can cause considerable damage to the fig trees. Damage ranges from defoliation (anthracnose and fig rust) to loss of fruit (fig mosaic, endosepsis and aspergillus).
Copper based fungicides are used to control anthracnose and fig rust. Aspergillus and endosepsis are controlled by destroying the crop for the year and applying diazinon granules to the trees. Trees infected by mosaic should be destroyed to prevent the spread of the disease.
In addition to the diseases described in this article, figs are very susceptible to pests called nematodes in sandy soils. The nematodes attack the roots of the trees, stunting their growth.
