Fig Tree Damage
Fig trees are deciduous trees that produce a fruit called a fig. A fig tree can grow 10 to 30 feet tall and equally as wide. The fig tree may suffer damage from various forms. This includes fungi, beetles, nematodes and other insects. They can attack the root system, leaves, and particularly the fruit that it bears and leaves the fig tree susceptible to damage. Does this Spark an idea?

Leaf Rust
-
Leaf rust is a serious fungal disease that commonly affects the fig tree. It is caused by a fungus that attacks the leaves and causes yellow spots. Over time, it causes defoliation and decreased yields. It is more common in rainy seasons and areas of high humidity.
Beetles
-
Flea and leaf beetles cause damage to fig trees. They damage the shoots and leaves. Other beetles such as sourbug and dried fruit beetles can cause souring of the fig fruit. As they feed on the figs, they leave behind a fungus that causes the fruit to sour. Fig tree producers speed up the ripening of the fig tree to avoid insects such as beetles from eating and spoiling the fruit.

Vinegar Flies
-
Vinegar flies, commonly called fruit flies, are attracted to the smell of rotting figs that fall off of the tree and onto the ground. They then feed on the fruit on the tree and carry bacteria and fungus into the figs. This causes the fruit to sour.
Nematodes
-
Nematodes are parasitic worms that are found in the soil. The fig tree is susceptible to nematodes. They attack the roots of the fig tree and cause damage to them. This leads to stunted growth. There may not be any obvious signs of damage besides the stunted growth early on, but if you look in the soil near the roots, you will see a large gall, or swelling on the roots. Eventually, nematodes can destroy the root system, which will kill the fig tree.
Fig Wasp
-
Blastophaga grossorum is a tiny wasp that pollinates fig trees. The wasps themselves are not destructive to fig trees, but in the process of pollination, they can introduce various bacteria and fungus into the fig tree. This can lead to decreased yields and souring of the fruit.
