Rust fungi are obligate plant pathogens that only infect living plants. Infections begin when a spore lands on the plant surface, germinates, and invades its host. Infection is limited to plant parts such as leaves, petioles, tender shoots, stem, fruits, etc. [3] Plants with severe rust infection may appear stunted, chlorotic (yellowed), or may
The main ways in which myrtle rust can be spread are by: the movement of infected plant material, the movement of contaminated equipment, wind, water and gravity, animals, humans and/or vehicles. [15] Myrtle rust may remain on a single host plant to complete its life cycle, which can be as short as 10–14 days. [5]
Albugo candida, commonly known as white rust or white blister rust, is an obligate plant pathogen in the family Albuginaceae that infects Brassicaceae species. [2] (Although called a "rust" and a fungus, it is an oomycete.) It has a relatively smaller genome than other oomycetes. [3]
White rust plant diseases caused by Albugo fungal-like pathogens should not be confused with white pine blister rust, Chrysanthemum white rust or any fungal rusts, all of which are also plant diseases but have completely different symptoms and causal pathogens.
Albugo occidentalis, the causal agent of spinach white rust, is an oomycete plant pathogen, although some discussions still treat it as a fungal organism. Albugo occidentalis is one of the most important spinach diseases in North America, found throughout the United States east of the rocky mountains.
White rust is a disease in plants caused by the oomycete Albugo candida or one of its close relatives. Plants susceptible to this disease generally include members of the Brassica family. [ 1 ] White rust has been known to cause agricultural losses in fields cultivating members of this family including broccoli , cauliflower , and Indian ...
Gymnoconia interstitialis, otherwise known as orange rust of raspberries, is a well-known disease of raspberries and blackberries throughout the eastern United States and southern Canada. The disease targets the usefulness of the leaves, attacking them until they die and fall off of the plant.
Infections can lead up to 20% yield loss. The pathogen is a Puccinia rust fungus. It is the most prevalent of all the wheat rust diseases, occurring in most wheat-growing regions. [1] It causes serious epidemics in North America, Mexico and South America and is a devastating seasonal disease in India.
