Wedding Celebrations: The Tour

Floriculturists visit CTAHR research stations on four islands

CTAHR played tour guide for the Hawai‘i Floriculture and Nursery Association’s first-ever “Wedding Celebrations: Floral Design Workshop and Nursery Tour.” Attendees, some from as far away as Canada and Pennsylvania, attended Wedding Floral Design Workshops on four Hawaiian Islands, led by famed floral designer Hitomi Gilliam (center, in black) and funded by the USDA and Hawai‘i Department of Agriculture.

Rapid ‘Ōhi‘a Death documentary features J.B. Friday

UH plays a vital role in researching and raising awareness of Rapid ‘Ōhi‘a Death (ROD), a disease that is killing off the native and iconic ‘ōhi‘a lehua tree. CTAHR and other UH scientists are working with state and federal agencies and non-governmental organizations to learn about this disease and to assess what can be done to protect ‘ōhi‘a for future generations.

CTAHR-led pruning and pesticide trials help local growers

CTAHR faculty and staff, with the support of HDOA, USDA, and grower-cooperator Greenwell Farms, have conducted research trials on coffee-pruning techniques and pesticide residues in green coffee beans at the Kona and Mealani Research Stations. Information and outreach from both trials will increase farmers’ ability to manage coffee berry borer (CBB) and produce high-quality specialty coffee.

Preliminary results from the first year of harvest in the three-year pruning trial show that single or double vertical, hand-hedged trees provide nearly 1.5 times greater yield in the first season of harvest compared with Kona-style pruned coffee trees, and 3 times greater yield compared with stumped trees. However, pruning, de-suckering, and harvesting the hand-hedged trees also requires about twice as much labor.

CBB can be managed while using all these methods of pruning, provided that there is proper field sanitation in and around the farm and that Beauveria bassiana sprays are well timed and provide good coverage.

Results of the coffee pesticide residue trial determined that a synergist, piperonyl butoxide or PBO, was present in green (dried, unroasted) beans when coffee berries were sprayed up to 105 days pre-harvest. The PBO residues were greater than those allowed by export countries such as Japan. The researchers are recommending that growers avoid using products containing PBO on coffee so as to eliminate the risk of rejection for exported coffee to such countries. Other pesticides tested did not result in detectable residues in green coffee.

Project faculty and staff Stuart T. Nakamoto (pruning project), Andrea Kawabata, Matt Miyahira, Julie Coughlin, and James Kam are welcoming participants to meet growers and learn more about these and other coffee research and updates at the Hawaii Coffee Association Conference at the Ala Moana Hotel on July 25–28. CTAHR coffee project and outreach updates will be provided on Friday, July 26, and from the college’s educational booth throughout the event.

Banding Together Against the Invaders

Invasive species conference brings together a variety of partners

Combatting invasive species requires the efforts of university programs, state agencies, and non-profit organizations. CTAHR plays a major role in coordinating their sometimes disparate areas of expertise and agendas, integrating the relevant information and bringing them together for a common cause. One important step in that direction is the invasive species conference that Kaua‘i invasive species Extension agent Roshan Manandhar and CTAHR CES are organizing.
