Crotalaria or Sun Hemp were used to determine the effect of cover crops aid in organic pest management 

Jari Sugano, Dr. Stuart Nakamoto and Kelvin Sewake cover fruit fly suppression and how risk management tools such as crop insurance can be used to help growers maintain income levels when new pest and diseases causes drops in yields and profits. 

Thank you to all of LIFE's program partners for a great field day event in Waialua, Oahu. Special thank you to Poamoho Farms for allowing us to hold the field trial and event at their farm.

Organic Tomato Field Day

Preliminary Screening for TYLC, TSWV and PepMoV Resistance

Friday, May 25, 2012

Poamoho Farms
65-200 Poamoho pl.
North Shore, HI 96791

Tomato yellows leaf curl virus (TYLCV) was first identified in tomato in November 2009 on Oahu. Plants become chlorotic, stunted, leaflets cup upwards and flowers abort.  This virus is transmitted by the silver leaf whitefly and sweet potato whitefly.   Tomato spotted wilt virus (TSWV) is another economically important plant virus to commercial operations.  Pepper mottle virus (PepMoV) was recently Identified in tomato in 2011 on Oahu.  Fruits show similar symptoms to TSWV.  The combination of TYLCV, TSW and PMV has made it difficult and for growers to maintain yields and profits.  UH CTAHR has conducted previous trials screening for double resistance in conventionally grown tomatoes.  This trial looks at triple resistance in new tomato varieties and the viability of producing tomatoes organically.  Stop by and see the horticultural characteristics of these promising varieties in this organic field trial.  Six globe type varieties include Charger(Determinate), Volante(Determinate), Kewalo(Determinate), Tribute(Determinate), Pamella(Indeterminate), and Sacramento(Indeterminate).

IYSV Field Demo and Best Management Overview

LIFE and RMH held an educational workshop on Iris Yellow Spot Virus (IYSV) in Waianae on May 4, 2012 at Katsu Kobashigawa's farm. Dr. John Hu and Dr. Wayne Borth started off the workshop by talking about the pathogen, IYSV. Maui Extension Agent, Robin Shimabuku provided an overview about the insecticide trials conducted in conjuction with emeritus Extension specialist, Dr. Ronald Mau. Extension agent Jari Sugano provided an overview of IYSV best management practices (included insect vector identification, field scouting, cultural practices, insecticide resistance management, pesticide education, etc.) and shared an additional tool in managing IYSV, USDA crop insurance programs. CTAHR pesticide specialists, Dr. Mike Kawate, Charlie Nagamine, and Cathy Tarutani were present to answer grower's questions regarding pesticide use, as well as Daisuke Inoyama and Steven Ogata from HDOA. CTAHR entomologists, Drs. Koon Hui Wang and Helen Spafford along with Dr. Ted Radovich and Jensen Uyeda from the CTAHR Sustainable and Organic Agriculture program were also there to support the group's educational efforts and provide technical assistance to growers with questions. Representatives from agricultual chemical companies such as BEI, Pacific Agricultural and CPS Hawaii were also in attendance. Extension agent Steve Fukuda (semi retired), Shimabuku, and Kawate organized a demonstration using kaolin clay to show how changes in spray variables affect overall coverage.

Dr. John Hu provides overview of IYSV in English and Chinese 

Dr. Wayne Borth discussed the different techniques used to identify the disease

Extension agent Robin Shimabuku shared advances based on Maui's insecticide trials.  

Extension agents, Robin Shimabuku and Steve Fukuda utilized kaolin clay to demonstrate the role of spray coverage in onion thrip management 

Changes in spray variables (such as nozzles, PSI, speed, etc) affect spray coverage

Growers were able to see first hand IYSV symptoms in a field setting 

Green onions sprayed with kaolin clay for demonstration purposes 

Kaolin clay allowed growers to see where the spray was deposited. In previous CTAHR spray demonstrations, a fluorescent dye was used with a black light system.

Weed management is important as weeds such as pig weed serves as a host for IYSV

Special thanks to Katsu Kobashigawa and Lisa Salazar for hosting the LIFE/ RMH educational event.
