Research and Development of Dragon Fruit Cultivars for Hawai`i


Background

Dragon fruit, also referred to as pitaya, is the fruit of climbing cacti in the genus Selenicereus, formerly Hylocereus, mostly endemic to Central and South America.  The fruit is very popular and there is increasing awareness of its many health and nutritional benefits. The lucrative price of the fruit and its byproducts, and its relative ease of production lead to its increasing importance as a crop throughout most of the tropical areas of the world.  Here we will report on the progress of our research and provide a compilation of references relating to this research.

Dragon Fruit Cultivation in Hawai`i.  The fruit can be grown in all the lower elevation areas of the Hawaiian islands and it has great potential for becoming an important crop here.  However, the fruit of most varieties are only seasonably available, it is highly perishable and has a short shelf life.  Exports of the fruit and cuttings for propagation from Hawai`i to the U.S. mainland are also prohibited by the U.S. Department of Agriculture’s plant quarantine regulations, which do not allow cactus plants or plant parts to be shipped there (USDA 2020).  Imports of cuttings into Hawai`i are also regulated (Anonymous 2026). Fruit juice, frozen fruit products and other higher value products could be produced from dragon fruit and exported but the processing facilities and infrastructure to do this are not available.

Another impediment to growing dragon fruit is the lack of information on the performance on the various species and varieties in Hawai`i, particularly in xeric areas with new, highly pervious volcanic soils.  These underutilized lands generally do not support many intensive agricultural activities but may be well suited for dragon fruit cultivation because of their lower cost and reduced requirements for controlling fast growing, highly invasive weeds present in areas with better soils.


Diseases of Dragon Fruit

Stem Canker Disease (SCD).  As we began plantings of many different varieties of dragon fruit at our experimental farm site in Ocean View, many of the plants began to develop orange spots on their stems and some of these infections resulted in soft rot of the affected stems or loss of entire plants.  The disease appeared to be dragon fruit stem canker disease (SCD). A specimen from an affected plant was submitted to the University of Hawai`i’s Agricultural Diagnostic Service (ADSC) in Hilo for diagnosis.  The laboratory found the infection to be Neoscytalidium dimidiatum, the fungal pathogen that causes SCD.  We immediately reported this to the Hawaii Department of Agriculture and Biosecurity (HDAB).  There was no response.

Observations. The disease exhibits highly variable characteristics on our plants.  Some species and varieties appear to be resistant.  Others develop only small orange lesions while the infection rapidly progresses on others resulting in soft rot of single stems or whole plants.

Importance of SCD. The disease has caused devastating crop losses in Florida and other dragon fruit growing areas.  The fungus that causes it is of worldwide distribution, and it affects many different crops.

Control strategies include pruning and sanitation in the winter and early spring, removal of affected plants and use of fungicides (Hong et al. 2023).

Fungicides. Only a few conventional fungicides and some organic fungicides have been registered by the U.S. Environmental Protection Agency for control of SCD in Florida (Hong et al. 2023).  These do not appear to be available in our area.

Risks to Human Health. The fungus that causes SCD in dragon fruit is also a human pathogen causing various dermatitides. One serious ocular infection (endophthalmitis) was reported in China.  It resulted from a corneal scratch caused by an infected dragon fruit (Qi et al. 2025).  Infections of other organ systems have occurred in immunocompromised individuals that may be particularly susceptible [Alamei et al. (2021) and Garinet et al. (2025)].

To minimize these risks, we recommend that those working with infected plants use appropriate personal protective equipment including goggles and disposable gloves.  Tools and other equipment that will be reused should be disinfected after use.


 

Yellow Stem Rot (YSR).  We have also observed a low incidence of what appears to be another rot disease of different morphology than SCD at our experimental farm.  Unlike SCD, it does not begin with the small orange spots typical of SCD and it results in rapid yellowing, then browning and soft rot of whole stems. Its appearance is very similar to the disease reported in India caused by Lasiodiplodia species (Genesan et al. 2023).  We have not been able to have specimens tested because of a recent closure of the ADSC laboratory.

White Spot Disease (WSD).  In mid-March of 2026, our area if Hawai`i experienced multiple severe storms known as “Kona Lows” over a two-week period resulting in 20 inches of rain. After about one week of rainy conditions, we began to observe large, dense areas of fine white spots on the stems of several varieties of dragon fruit at our experimental farm.  The spots initially were separated and soon merged to cover whole areas of the stems.  The affected areas were mostly those facing upward where water would tend to collect.  The appearance of the disease areas was not typical of SCD that usually begins with isolated orange spots.  Its cause is unknown and the potential of acidic volcanic ash deposits from the recent eruptions of the Kilauea volcano causing or contributing to this condition cannot be ruled out. We have not been able to have specimens tested because of a recent closure of the ADSC laboratory. As of this writing in late March 2026, we are monitoring the progress of the disease and will provide updated information as it becomes available.

Research and Development Objectives

The primary research objectives of this project are to collect data on the performance and disease resistance of the various species and cultivars in Hawai`i and to investigate methods and fungicides for controlling dragon fruit stem canker and other diseases that are economical to use and compatible with organic certification requirements.

Data from this research will be used to select cultivars for propagation and distribution in Hawai`i.


Project Milestones and Completion Status

This project consists of several steps summarized here with their completion status.  The dates are approximate.

1. Acquisition, Treatment and Rooting of Research Specimens

Progress Notes: In 2024 we acquired seeds and numerous unrooted cuttings of seven species and approximately 30 different varieties of dragon fruit, primarily from growers on the U.S. mainland.  These were reinspected, treated with a copper-based fungicide, rooted in pots and observed at our certified research nursery at Discovery Harbour.  Additional cuttings and seedlings of Kona pink, red, white, yellow dragon fruit were produced at the nursery.

Status:  In late 2024 all the seedlings and rooted cuttings were treated again with the copper fungicide and moved to our experimental farm for planting.

2. Farm Planting

Growing Supports.  Our experimental farm is surrounded by a six-foot-high chain link security fence.  The fence posts were placed in holes filled with cement to ensure support against the strong winds in the area.  Dragon fruit plants are also heavy, climbing plants and need a strong support system to grow on. We intended to use the fence and its posts for this purpose.  There are also large areas of the farm site covered with basaltic lava rocks and rubble that are also suitable for growing dragon fruit.  Examples of the potted plants are below:

Soil.  Soil at the farms site is scant and volcanic consisting of fines from cinders and crushed a‘ā, a basaltic lava rock with rough, jagged surfaces. It has very low content of organic matter and extremely porous with low water retention ability.  For planting holes and filling pots we use a manufactured soil media consisting of approximately equal volumes of volcanic cinders, fines and ground macadamia nut hulls.  A dressing of shredded mulch from the municipal waste transfer station at Waiohinu is applied to the top of soil media of the potted plants and around the plants in the ground.  Small rocks are then placed on top of the mulch to prevent it from blowing away and to reduce water evaporation.  This method is based on the agricultural methods practiced by the early Hawaiians in this area of Hawai`i island.

Irrigation. New plantings of dragon fruit in pots were watered about every two weeks until they were rooted and showed signs of new growth.  Thereafter, they received no irrigation.

Fertilizers.  A dry, granular fertilizer with a N:P:K ratio of 15:15:15 (Gaviota Blend 1491, manufactured for BEI Hawaii, 311 Pacific Avenue, Honolulu, HI 96817), is applied to the soil around the plants about every two months.  The nitrogenous component of the fertilizer his a slow-release formulation consisting of polymer coated urea. The fertilizer also supplies calcium, magnesium and sulfate.

Progress Notes: Large numbers of the common red, white and yellow varieties from our nursery were planted directly in the ground along the base of rock piles.  The other varieties were planted in large plastic pots with painted on identification labels.  They were located adjacent to fence posts to provide strong support for future growth.

Status:  Within the first year after planting all the plants were growing and producing new stems.  Some were lost to stem canker disease.  Most of the stems growing near or through openings in the fence were chewed off.  We learned that mouflon sheep (Ovis gmelina), an introduced ungulate species on Hawai`i island, and present in the area around our farm consider all varieties of dragon fruit to be a special treat!

 

3. Fungicide Formulation and Testing

Overview: Several different classes of fungicides for treatment of SCD  have been developed or are the subject of current research (refer to references).  Our intent is to develop and test fungicides that would be easily accessible and made from low cost ingredients that are not likely to require EPA registrations and compatible with organic certification requirements.  Sodium salt has shown promise in controlling SCD (Riska et al. 2023) and would conform to our development criteria. This led us to develop a proprietary formulation based on inorganic salts.

Progress Notes:  We are testing the proprietary fungicide and the use of a broad spectrum, EPA registered copper octanoate (copper soap) based fungicide (Bonide Captain Jack Fungicide) that is compatible with organic certification.  The fungicides are applied when there is evidence of SCD or other diseases on the dragon fruit plants.

Status:  There is insufficient data to access the effectiveness of the two fungicides. Preliminary observations indicate that our proprietary inorganic salt solution maybe be more effective than the copper-based fungicide.  However, it is highly soluble in water and is probably washed off the plants by rain.

4. Observations

Overview: Observations of plant growth, bloom cycles, fruit production, and pest and diseases will be made and recorded at a minimum frequency of every three months or as staffing levels allow.

Progress Notes: Observations are ongoing.

Status: All the seedlings and cuttings planted have rooted and are producing new stems.  Some  plants, particularly those planted in the ground have been lost to SCD and replaced.  Several have flowered and two varieties – Yellow and Robles Red have produced fruit.  Most have not bloomed probably because of their immaturity.

 

5. Sales of Seedlings and Cuttings

Overview: We intend to become a primary supplier of dragon fruit seedlings and cuttings for Hawaiian growers.

Progress Notes: For the last several years we have been the only supplier of organic, seed grown dragon fruit plants on Hawai`i island.  These were of the white, yellow, red and Kona Pink varieties.  These are in strong consumer demand but are costly and slow to produce from seeds.

We are planning to begin sales of a much wider array of cuttings from Hawai`i adapted varieties grown at our experimental farm.  Recommendations will be based on performance data from our research activities.  Inspection procedures and methods to minimize the risk of plant disease transmission from cuttings will be developed before sales commence.

Status: In March of 2026 the first wide selection of treated cuttings from our experimental farm was offered for sale from our ONLINE STORE.  As we develop more data on the performance and disease resistance of these varieties it will be posted in the product descriptions to assist customers in making cutting selections.
