Webinars are Scheduled on Coffee Leaf Rust and New Fungicide

Two free coffee leaf rust webinarswill be held in April to help inform Hawaii coffee growers on the potential use of a fungicide to combat coffee leaf rust.


The devastating coffee pathogen has been found on Maui, Lanai, Hawaii island and Oahu and poses a serious threat the state’s $56 million coffee industry, according to the state Department of Agriculture.

Earlier this month, the DOA filed a request for emergency exemption with the U.S. Environmental Protection Agency to allow the use of a fungicide, Priaxor Xemium, on coffee plants in Hawaii. The fungicide is approved for use on other agricultural crops, but EPAapproval is needed to allow its use specifically on coffee plants, the department said Tuesday.

Hawaii researchers believe that Priaxor has the ability to inhibit the coffee leaf rust spore germination and growth on the coffee plant leaves, unlike currently approved contact fungicides that kill spores on the outside of the leaf.


In anticipation that the EPA may approve the request by the end of April, the University of Hawaii College of Tropical Agriculture and Human Resources and the DOA will host two Zoom webinars on the safe use of the fungicide.


The webinars will take place from 4:30 to 5:30 p.m. Thursday and April 8. Registration is required at www.HawaiiCoffeeEd.com/priaxor.
