Identifying Fig Rust

The early signs of fig rust are small yellow spots on the upper surface of the leaves. These spots, also known as lesions, will grow larger over time and turn a reddish-brown color, but they tend to remain relatively smooth.

When the infection is severe, the leaves will turn yellow or brown, particularly around the edges, and fall off the tree prematurely.

Rust typically appears during late summer and in severe cases, it can cause the fig tree to lose its leaves in a matter of weeks. This can have a significant impact on the tree's growth and yields, as well as its overall health.
