What are the symptoms of Cedar Apple Rust on fruit trees?

Cedar Apple Rust is a common fungal disease affecting apple and crabapple trees that is characterized by specific symptoms. The correct answer focuses on the presence of spots on both the fruit and the leaves, which is a hallmark of the disease.

The spots typically appear as yellow or orange lesions and can vary in size. These symptoms occur as the pathogen develops, transferring from junipers to apple trees, leading to these distinctive markings. The disease cycle involves the production of spores that infect the leaves and fruit, causing visible damage.

In contrast, other symptoms such as blackened fruit and leaves, excessive pitch secretion, and wilting branches, are indicative of different types of plant stress or other diseases. Blackened fruit and leaves may be seen in cases of severe fungal infections but are not typical for Cedar Apple Rust. Excessive pitch often suggests canker diseases or environmental stress rather than fungal infections like Cedar Apple Rust. Wilting branches could indicate water stress or root issues, rather than a direct impact from Cedar Apple Rust. Understanding these specific symptoms helps in identifying Cedar Apple Rust and distinguishing it from other problems that can affect fruit trees.
