Webinars Scheduled For Coffee Growers On Possible Fungicide Use

State of Hawaii Department of Agriculture

Two free webinars have been scheduled in April to help inform Hawai`i coffee growers on the potential use of a fungicide to combat the coffee leaf rust (CLR). Earlier this month, the Hawai`i Department of Agriculture (HDOA) filed a request for emergency exemption with the U.S. Environmental Protection Agency (EPA) to allow the use of a fungicide, Priaxor® Xemium, on coffee plants in Hawai`i. The fungicide is approved for use on other agricultural crops, but EPA approval is needed to allow its use specifically on coffee plants.

In anticipation that EPA may approve the request by the end of April, the University of Hawai`i – College of Tropical Agriculture and Human Resources (UH-CTAHR) and HDOA will be hosting two Zoom webinars to help educate coffee growers on the safe use of the fungicide.

The webinars have been scheduled for:

  • Thursday, April 1st and Thursday, April 8th from 4:30 p.m. to 5:30 p.m.
  • Registration is required and may be completed at: HawaiiCoffeeEd.com/priaxor
  • Webinars are free.
  • For more information on the Zoom webinars, contact UH-CTAHR Associate Extension Agent Andrea Kawabata at andreak@hawaii.edu or call (808) 322-0164

Hawai`i researchers believe that if approved by EPA and used properly, Priaxor has the ability to inhibit the CLR spore germination and growth on the coffee plant leaves, unlike currently approved contact fungicides that kill CLR spores on the outside of the leaf.

CLR has been detected on Maui, Hawai`i Island, Lana`i and O`ahu and is a serious threat to the state’s $56 million coffee industry.

CLR is a devastating coffee pathogen and was first discovered in Sri Lanka in 1869 and can cause severe defoliation of coffee plants resulting in greatly reduced photosynthetic capacity. Depending on CLR prevalence in a given year, both vegetative and berry growth are greatly reduced. There are multiple long-term impacts of CLR, including dieback, resulting in an impact to the following year’s crop, with estimated losses ranging from 30 percent to 80 percent.

Short Term Strategies
with Jacques Avelino of CIRAD* and Andrea Kawabata of University of Hawaii CTAHR

Jacques will discuss the biology of the causal agent of coffee leaf rust: the fungus Hemileia vastatrix and some epidemiological considerations. He will explain how meteorological variables, topography, coffee tree characteristics, natural enemies and management, particularly nutrition and shade, affect coffee rust development. This knowledge can be used to improve coffee rust management at farm and regional levels.

Andrea will provide updated information on approved fungicides for coffee in Hawai’i to help combat Coffee Leaf Rust, including application protocol. She will also cover necessary general farm practices, hygiene, and sanitation protocol that producers should be implementing on their farms immediately to avoid spreading CLR spores.

*CIRAD is the French agricultural research and international cooperation organization working for the sustainable development of tropical and Mediterranean regions.

Research, Resources & Regulation
with Kevin Hoffman of HDOA and Lisa Keith of USDA and PBARC

Kevin will provide an update to attendees on the most current information available to HDOA including new quarantine restrictions.

Lisa will focus on the pathology of coffee leaf rust in Hawaii, including what we know, what we don’t know, and short and long term research efforts to manage CLR in Hawaii.
