WHO CAUSES IT?
Tranzschelia pruni-spinosae is a pathogenic fungus that causes the disease known as rust in various plants, including apricots. This fungus is characterized by its ability to produce spores at different stages of its life cycle, which allows it to spread easily through air and water. The fungus can survive the winter on plant debris or alternative host plants, facilitating its reappearance in the following season. Tranzschelia pruni-spinosae thrives in conditions of high humidity and moderate to high temperatures.
