Coffee leaf rust, a deadly fungus, has been discovered on all of Hawaii’s major islands, according to the Hawaii Department of Agriculture.
The state gathered samples from Kauai and Molokai in the previous month and confirmed the existence of coffee leaf rust.
The invasive pathogen was initially discovered in Hawaii in October 2020 on Hawaii Island and Maui, and then in January 2021 on Oahu and Lanai.
On July 9, a commercial coffee farmer in Kilauea, Kauai, verified the presence of coffee leaf rust. The fungus has been on the island for at least six months, according to officials.
