HAWTHORN RUST Meaning and
Definition
-
Hawthorn rust is a plant disease caused by the fungus Gymnosporangium globosum, which primarily affects trees and shrubs belonging to the Crataegus genus, commonly known as hawthorns. This fungal infection can also affect plants from the Rosaceae family, including apple, pear, and quince.
Hawthorn rust produces distinctive symptoms, including the development of yellow-orange to rusty-brown colored pustules on the leaves and stems of infected plants. These pustules, referred to as telia, contain spores that are responsible for the spread and subsequent infection of neighboring plants. The infected leaves may also display yellowing, browning, or premature defoliation, leading to reduced plant vigor and overall health.
The disease cycles between the hawthorn and related plants, requiring both hosts in order to complete its life cycle. It infects hawthorns during spring and summer, producing spores that are then carried by wind or rain to nearby susceptible plants, such as apple trees. The resulting infection on the secondary host produces different pustules called aecia, which release spores that can re-infect hawthorns.
The management of hawthorn rust largely involves prevention and control measures. These include removing and disposing of infected plant material, practicing crop rotation, and maintaining good sanitation practices. Fungicidal sprays may also be used in severe cases, especially during critical stages of plant growth. Ornamental hawthorn cultivars with resistance to rust are often recommended for planting to minimize the risk of infection.

Etymology of HAWTHORN RUST
The word "hawthorn rust" is composed of two parts: "hawthorn" and "rust".
1. Hawthorn: The term "hawthorn" refers to a type of tree or shrub that belongs to the genus Crataegus within the Rosaceae family. The word "hawthorn" originated from Middle English "hagethorn", which combines "hage" meaning "hedge" and "thorn" referring to the sharp spines present on the plant. The Middle English word, in turn, came from Old English "hagaþorn", with "haga" meaning "enclosure" or "hedge" and "þorn" meaning "thorn".
2. Rust: "Rust" is a term used to describe a form of plant disease caused by various fungi.
