Puccinia xanthii
Puccinia xanthii is a fungal pathogen of plants in the Asteraceae, and can infect hosts from at least 42 genera within that family, most notably species in the Xanthium and Ambrosia genera. This pathogen was discovered growing on Xanthium strumarium in North Carolina, United States in 1822. Common names of P. xanthii include Summer Rust and Cocklebur Rust.

Range & habitat
Puccinia xanthii is native to the continental United States, Canada, Mexico, Hawaii, Cuba, Haiti, the Dominican Republic, Puerto Rico, and the Bahamas. This fungus has been reported in several countries throughout Europe, Asia, Africa and Australia; often following the introduction of invasive host plants from North America or intentional release as a biocontrol agent.
Europe. Researchers have detected P. xanthii in Bulgaria, southern France, Hungary, northern Italy, Romania, Spain, and the former Yugoslavia (Bosnia, Serbia, Slovenia, Montenegro, Macedonia, Herzegovina, and Croatia). Puccinia xanthii was found growing on Xanthium orientale subsp. italicum in eastern Hungary in December 2002.
Asia. Puccinia xanthii has been detected in India, Indonesia, Japan, Pakistan, and Korea. Puccinia xanthii was found growing in lesions on leaves of Xanthium orientale in Okcheon-gun, Korea in October 2021 and from Xanthium orientale subsp. italicum in the Liaoning Province of China in August 2013. Xanthium orientale subsp. italicum was first found in Beijing, China in 1991 and has been shown to decrease the biodiversity of native flora and cause human health hazards from allergenic pollen. As a result of this, the P. xanthii is considered beneficial in this area as it may decrease the vigor of this weed. …
