Volume 2, No. 3 2008 Fusarium Wilt of Orchids The Nobile Dendrobium Volume 2, No. 3 2008 | ICOGO BULLETIN 1 2 ICOGO BULLETIN | Volume 2, No. 3 2008 A Message from the President By Andy Matsui, President, International Commercial Orchid Growers Organization T he financial crisis triggered by the U.S. has spread throughout the world. As a result, clouds are gathering over the global orchid industry, despite the earlier projections of steady growth. However, the development we see now is not caused by the global recession alone. The E.U. region, which was said to have the most promising orchid cultivation in the world, seems to have already faced the excess supply in the summer of this year due to unreasonable production increases that have occurred over the past several years. Therefore, even if we had managed to forestall a global recession, a sharp decline in prices would certainly have occurred in the summer of next year. Now that the recession has occurred, it will provide a tailwind to put more pressure on the orchid market in the E.U. Orchid cultivation in the U.S., which had been showing signs of a successful takeoff, is now looking doubtful due to the turmoil in the market. This was brought on by unplanned production increases in Florida, where the number of orchid growers has doubled to 70 over the past two years, and in parts of California. What we have learned from these painful lessons is that we should not have neglected to study the orchid market before deciding on a production increase, and that we should have spared no effort in developing the market following the start of that production increase. The orchid growers, before implementing their reckless production plans, should have engaged in serious dialogue with one another, as well as orchid propagators and marketers. We can consider potted orchid flowers as fresh produce. The world will continue to see population growth and economic growth, so it is not a bad idea for anyone to consider increasing the annual supply volume by 10% or so, unless the products are past their prime. However, any plan to supply more than this to the market in an attempt to expand the market and obtain profit would require reliable substantiation through marketing. This theory applies not only to the production of potted orchid flowers but also to the production of orchid plants around the world. Due to the excessive production of orchid plant in China, Taiwan, Thailand and even the nations of the E.U., it is currently estimated that orchid plants production exceeds the global demand by more than 60%. This oversupply of orchid plants is adding to the concerns over the future orchid market. The orchid, in all its cultivated varieties, may have outstripped poinsettia and become a step closer to achieving status as the “king of potted flowers,” but in the larger sense it is still a minor agricultural product. To grow the world orchid market steadily and ensure profits while expanding the industry, it is critical that orchid propagators, growers and marketers have close dialogue. I am confident that the quickest path to the success and growth of the world orchid industry in today’s global climate is to utilize the organization of ICOGO and drive dialogue among all the parties involved.

At the Foundation of Growth 4 ICOGO BULLETIN | Volume 2, No. 3 2008 Quality Media: New Zealand a High Quality Sustainable Resource Clive Washington Quality orchid growing media has become important as orchid production increases globally. Sustainable growing media is also increasingly important as global requirements to reduce carbon footprints become more main stream. The orchid growing industry is steadily increasing. Since 1996 sales of potted orchids have increased in the U.S. by well over 200%. In 2005 alone, sales increased from the previous year by 12% (USDA). This increase in sales in the U.S. as well as the cooperation with Taiwanese growers for export has seen a large increase in production. China is also moving on as a mass orchid producer and as the country develops further there is likely to be a greater domestic demand. As orchid growth moves into the future, we see the occurrence of new high tech growers. Automation of nurseries, in depth research and development of growth cycles, climate changes and plant variety differences means orchid growing is no longer the back yard venture it once was. To carry out high tech ventures such as these but still produce a cost effective potted orchid requires a great deal of financial input. With fuel and labor costs skyrocketing, efficiencies and cost reductions for the grower are a must. How do growers increase profits? Growers put a considerable amount of expenditure into infrastructure such as land, glass and plastic houses, racking, heating (and cooling in some areas). In addition to this the purchase of fertilizers, growing media, plant stock and labor are all significant costs. All these costs contribute to the final cost of growing a flowering orchid. All too often growers try to increase profits by reducing costs and ignore the negative impact that this could potentially have on production. Growing media is often one of the first aspects of a nursery to be downgraded. Growers can be quick at times to switch to low cost/low quality inconsistent growing media often not realizing this media could be reducing production and increasing other production costs. It is true that you can grow orchids in almost any media; however the secret to increasing profits is to use quality consistent growing media to improve growth rates and have lower mortality. This results in easier management through the reduction of labor, energy, water and fertilizers. There are two main growing media for orchid: Bark (including fir and pine) and Sphagnum moss. Coir fiber and peat are used in some areas and in mixes. Sphagnum moss was originally the key product for growing Phalaenopsis; however, the past 10 years has seen a change in trend in growing media to finer bark grades. These are progressively becoming used more with portions of coir fiber which is seen as a benefit with some growers. Trends have also been affected by problems occurring in regions with sourcing of raw material and disease. For example, Douglas fir is a host plant species for the pathogen that causes SOD (sudden oak death that is caused by Phytophthora ramorum). This has restricted the use of many types of local media which has lead to growers looking offshore for bark based media or alternatives. technique to pot up correctly but the sterile nature of good quality Sphagnum moss can lead to cost effective production, provided good quality material is used. The three main suppliers of sphagnum moss are China, Chile and New Zealand. New Zealand sphagnum moss resources have been considered the best by growers around the world for more than 25 years. The New Zealand species is Sphagnum cristatum; a larger leaved robust moss which doesn’t over-compact and lasts well in the pot. However compared to Chilean and Chinese moss it is far more expensive to produce. Land production and labor costs are much higher in New Zealand, however the cost of production is at a relatively stable level and the resource is in a cyclic and renewable state. The focus here is also on quality product with systems in place to provide consistent grades for specific growers. This combination will allow the country to continue to supply high quality renewable Sphagnum moss for as long as there is a demand for it. At the moment New Zealand moss processors have 600 tones of sphagnum moss available each year (approximately 120 million 10 cm pots). Currently the only threat to supply is a fight for prevention of turning moss swamps into dairy farms which at this point is more profitable for New Zealand farmers. New Zealand sphagnum moss producers have to keep margins to a bare minimum as both Chilean and Chinese moss sources are cheaper. Chilean sphagnum moss is a less stable resource. Over 15 years ago, Chile was found to be a bountiful supply of sphagnum much like that of New Zealand. Labor was cheaper and quality comparable to New Zealand grades; the only difference being that the Chilean moss (Sphagnum magellanicum) differed in structure and color. Unfortunately rather than cooperate to form a cyclic renewable resource, many areas have been stripped by opportunisttraders. ”Quality” resources are increasing in scarcity as swamps Sphagnum moss Sphagnum moss has been a very good growing media for certain orchid variety. As sphagnum moss is easily managed and is efficient in both irrigation and fertilization, it is a good media for growing Phalaenopsis in many locations. It does require some Fig. 1. An electron micrograph of fresh fir bark. Studies by Pacific Wide (NZ) Ltd. have shown that the Chinese sphagnum moss accumulates salts to a greater extent than both New Zealand and Chilean moss. Volume 2, No. 3 2008 | ICOGO BULLETIN 5 are re-harvested after only a few years rather than the preferable 7 years. Chinese moss, although still available in some regions, is of poor quality. The main species being Sphagnum palustre, is softer in nature, compacts too easily and breaks down faster than the more robust Sphagnum cristatum from New Zealand. It is therefore less suited to high tech plant growth. Bark Bark is a prominent media type for growing orchids in Asia with many other countries now using 100% bark or bark mixes, with moss and coir. Bark chip based orchid media provides growers with good aeration, the ability to hold nutrient and a substance which the plant roots can adhere to. Cymbidiums have always grown well in bark but more recently, Phalaenopsis growers are moving to a small bark chip over moss to have more automated and consistent systems. Bark is a very general term, as there are major differences, pine and fir. Fir bark has a higher cellulose content compared to pine bark and although it may be more available in some areas, it will not last as long as a similar size pine bark particle. If one has plants for more than two years, for example, for cut flower production, this material will likely cause some nitrogen drawdown effect. Management may be more difficult. Pine bark, however, is more stable as a growing media due to higher amounts of lignin. It also contains a higher percentage of tannins, phenols and, waxes which give pine bark both the reddish color and the waxy nature of the raw material. Whilst pine bark is increasing in popularity for its ability to be a stable growing media, quality is dependent on pine species and growing areas. To produce a high quality growing media from pine bark, both the tannins and waxy nature are removed so that there are no phytotoxic effects, allowing it to hold onto water and nutrients. Many suppliers of pine bark around the world especially Portuguese pine bark do not age the raw product.. The particles may look good; however, they can repel water easily leading to inefficient water retention. Different species of pine grow in different countries. South African pine plantations consist of Pinus patula which can be a lot thinner; Chile, Australia, and NZ grow Pinus radiata also known as the Monterey pine (native to central California). It does not delaminate easily (splits between the layers) and has higher amounts of lignin. These characteristics contribute to a rounder nugget which aides in stability and longevity of this media compared to other growing media. In the late 1980’s Pacific Wide (NZ) Ltd. developed a method to remove the toxins and to age the New Zealand Pinus radiata bark. After the process to remove the toxin waste, the material is granulated and then aged to remove the outer waxy layer. The process to get it to a stage where the inside of the particle is still hard and stable but the outside is broken down to hold enough water and nutrient for orchids is a specialized one taking five important steps: removal of tannins by conditioning, limited aging to breakdown the outside, grading to certain sizes and removal of contaminants that may cause grower problems, and pH stabilization to bring the pH of the media up to suitable levels for orchids. The pH of Pinus radiata bark can be as low as 3.5 - 4 in the spring so this must be raised for good orchid growth. The benefits of a naturally aged, unsterilized, pH adjusted medium are that there is a very good population of natural beneficial microorganisms there to protect the plant. The pH stabilization adds both calcium and magnesium, important elements for plant growth and prolonged pH stabilization. Using larger grades (12 – 18 mm) will also mean that wetter media such as coir or sphagnum moss can be mixed with the media and still will last 5 years. Resources of Pinus radiata are plentiful. It is a renewable resource in all of the areas grown, especially New Zealand where there is currently 1.6 million hectares of Pinus radiata planted. As forestry is a main 6 ICOGO BULLETIN | Volume 2, No. 3 2008 component of NZ exports, it will be a commodity present in the long term future much like that of the sphagnum moss. With both sphagnum moss and aged Pinus radiata from New Zealand, the quality and consistency are closely monitored, the resource is cyclic and renewable, and the aim is to provide top quality media consistently so that growers can work more efficiently. The cost must reflect value in results. Therefore, whilst the cost when compared to local material may be twice as much, which has been experienced on many occasions, using a consistently higher quality medium allows for the reduction in irrigation time, nutrient consumption, mortality rates due to better plant health, and less labor costs. Advice to growers should be to find a medium of high quality no matter what the cost and then work with that material on a long term basis to make their growing systems more efficient. If the medium is consistent then, over time, cost effectiveness will prevail. ICOGO Fig. 2. An electron micrograph of raw Pinus radiata bark. Fig. 3.

In this article, it cites the benefits of applying 200 or 400 ppm Configure (benzylaminopurin or BA, a synthetic cytokinin) on Phalaenopsis to runoff two weeks before the beginning of cooling for flower induction. It cites that BA increases the number of inflorescence and results in a higher flower count per spike. However, orchid growers must be aware of the potential risks of using BA (Configure) to induce double spiking in Phalaenopsis. It is reported in a paper to be published soon in HortTechnology that BA can cause severely deformed spikes at a concentration of lower than 100 ppm. Although, BA may induce more double spiking, it can result in much reduced flower count on each spike, only 3-5 flowers per spike. There are also varietal differences in their response to BA. Growers, who are interested in this plant growth regulator, are advised to test a limited number of plants across varieties to make sure whether it has any undesirable effects on product quality. Fig. 1. BA may trigger double spiking, but the number of flwoers on each spike may be much reduced (photo by Bo-Hong Wu). ICOGO Fig. 2. Foliar BA application resulted in mulformed spikes.

Taean Orchids U.S.A., Inc. US Orchid Supplies. Inc. Westerlay Orchids Fusarium Wilt of Orchids David E. Wedge and Wade H. Elmer Fusarium wilt of orchids is highly destructive and economically limiting to the production of quality orchids that has steadily increased in many production facilities. Important crops such as phalaenopsis, cattleyas, and oncidiums appear to be especially susceptible to certain Fusarium species. Fusarium wilt appears to be more frequent and severe in commercial nurseries that have adopted newer production technology and pot formulations for fast production cycles. These new production cycles may be increasing the susceptibility of some orchids to this and other diseases. Increased disease incidence motivates growers to increase chemical applications in an attempt to control disease. However chemicals are often applied too late in the disease cycle for effective disease control. Ultimately, fungicides are applied unnecessarily, valuable time and labor are wasted, and the emergence of fungicide resistant pathogens are increased. Actual losses due to Fusarium wilt have not been calculated, but its incidence has increased in recent years. wilt is complicated by a number of factors. Inoculum is spread on transplants, pots, and in soil mixes. Fungus gnats, wind and irrigation water can also transport the pathogens. Our orchid studies indicate that new Fusarium infections are often misdiagnosed as ‘Black Rot’ caused by Phytophthora and therefore go unchecked due to the use of ineffective fungicides. Early in its disease cycle, Fusarium is readily wind dispersed throughout the greenhouse when the fungus produces small single celled spores called microconidia. Symptoms Fusarium disease symptoms include stunting, chlorosis, and wilt. Many times leaves appear shriveled and water-soaked. Although the disease appears to be more prevalent on phalaenopsis, the problem has been noted on other types of orchids, such as cattleyas and oncidiums. Fusarium wilt is typically a ‘bottom up’ disease in orchids. Infection probably occurs through the root zone or stem wounding and the disease progresses into the vascular tissues of the rhizome, stem, and pseudobulbs. A brown-black rot can extend into the pseudobulbs. An often diagnostic trait of Fusarium disease is the development of a pink–purple discoloration of the vascular tissue in the rhizome or stem. Biology The causal agent of Fusarium wilt is Fusarium oxysporum. However, some experts have found that F. solani is also associated with the disease and capable of causing wilt symptoms. Observations by growers have suggested that the onset of symptoms may be correlated with heat stress, high humidity, and heavy fertilization. Severely infected plants may die in one to three months and other plants linger in a slow decline. However, both infection-types are characterized by a significant loss of viable roots. Fusarium wilt commonly results in the death of the plant and losses often exceed 50%. Symptoms on orchids grown in Florida appear primarily during the heat of the summer and are greatest on young plants that have been transplanted from either culture flasks, community pots, or 2” pots. Heat stress, transplanting shock, wounding, and heavy fertilization predispose the plant to be more susceptible to infection. This disease remains a serious problem until the weather cools. However, it is important to note that the time of infection and the window of use for chemical and biological disease control efforts may have been weeks or months prior to the onset of symptoms. Figure 1. Fusarium wilt of oncidium showing discoloration and collapse of the plant. Later in the infection cycle the pathogen is spread by irrigation water, Fungus gnats, contaminated soilless mix, and other equipment when the fungus produces multicelled spores called macroconidia. Management The most effective control for Fusarium disease has historically been through development of crops with host resistance. However, there is no information on Fusarium resistant cultivars in orchids. Additionally, Fusarium diseases of ornamental plants are particularly difficult to control. Management of Fusarium Figure 2. Fusarium wilt of cattleya showing black discoloration and progression of ‘Bottom Up’ symptoms. Note the lack of viable roots in mature and seedling plants. Volume 2, No. 3 2008 | ICOGO BULLETIN 9 Growers can also manage the disease by routinely inspecting stock for disease symptoms and for the production of new roots with green tips. The proper management of irrigation water pH (pH 6.0 to 6.5) may help reduce infection. Chemical control Traditionally, plants were sanitized by drenching them with thiophanate-methyl or iprodione based systemic fungicides. However, our studies found that most Fusarium isolates were resistant to these two classes of fungicides. In contrast, chlorothalonil provided excellent protective activity while the systemic azoxystrobin provided suppression of most Fusarium wilt pathogens. Work done on Fusarium disease of other ornamentals suggests that fludioxonil (Medallion), triflumizole (Terraguard) and azoxystrobin (Heritage), provided adequate control of Fusarium wilt if applied during the early infection period. Currently, a new product called Palladium®, a combination of fludioninil and cyprodinil is in the registration process and may be available for use in late 2009 or early 2010. Use of efficacious fungicides from various chemical groups should provide growers with more options from controlling orchid diseases while managing fungicide resistance in the pathogen.

Starman The nobile dendrobium has been grown for many years in the history of orchid cultivation. The amount of production by commercial growers around the world has much increased in recent years. It is estimated that over 3 million nobile dendrobium will be produced in Europe, mainly the Netherlands, in 2008. In the United States, the Matsui Nursery alone produces over 130,000 pots yearly. Most of the commercially produced nobile dendrobium comes from the breeding program of Yamamoto Dendrobiums in Japan. Although some research on this orchid was conducted in Japan more than 30 years ago, little work has been done in recent years for modern commercial production. A research team at Texas A&M University, United States, consisting of Dr. Yin-Tung Wang, Dr. Terri Starman and their graduate students, has focused their work on the nobile dendrobium since 2004. Using the tetraploid clone Den. Red Emperor ‘Prince’ and a medium containing 50% peat, they discovered that the nobile dendrobium needs 100 ppm (mg/liter) of nitrogen, no more than 25 ppm of phosphorus, and 100 ppm of potassium during the period of active vegetative growth for best flowering. As a matter of fact, plants bloomed quite well even when no phosphorus was applied for more than one year. However, deficiency of nitrogen or potassium each causes early and severe defoliation and fewer flowers being produced. In Japan, the nobile dendrobium plants are cooled at low temperatures (8-10 °C or 45-50 °F) to result in leaf loss or leaves are removed manually before flowering. Therefore, flowering plants are sold without their foliage. In the United and Europe, the green foliage is needed on flowering nobile dendrobium plants. As a result, maintaining a proper feeding program to retain the foliage in a healthy and attractive condition is very important to obtaining products that are preferred by the consumers. It is generally believed that extended application of nitrogen interferes with proper flowering and promotes the formation of lateral shoots, in lieu of flowers. Plants that produce lateral shoots are a total loss to commercial producers because these nodes do not produce flowers. This research team found that applying nitrogen from planting through flowering did not affect flowering when plants were properly cooled. If plants do not receive adequate cooling, then, the pseudobulbs may produce lateral shoots with or without the continuous applications of nitrogen. Although, extended nitrogen application may make this condition much worse. Terminating fertilizer application early results in thicker pseudobulbs that mature earlier for forcing. Early termination of fertilization may delay the outgrowth of the second shoot which normally does not mature enough when plants are cooled for flower induction, therefore do not produce flowers. If two shoots are desirable, then, fertilizer should be applied for a longer period. Research has shown that delayed termination of fertilization extends the vegetative growth, particularly under warm conditions, and the terminal nodes may not produce flowers if plants are exposed to low temperatures before the upper nodes have become fully mature. 12 ICOGO BULLETIN | Volume 2, No. 3 2008 Regardless of temperature, once plants are removed from cooling and placed under higher temperatures for flowering, how long do mature plants need to be cooled at what temperature to induce flower initiation? To answer these questions, this research team used Den. Sea Mary ‘Snow King”. They found that two weeks at a constant 10, 13, 15, or 18 °C (50, 54, 59, or 64 °F) was enough for complete flower initiation. At 21 °C, some nodes failed to initiate flowers and the flower buds on some nodes aborted. Fig. 1. Den.

Orchids are renowned among horticultural products for their many varieties. Going forward, breeders will develop new hybrids through interspecies hybridization, as well as cultivars with shorter cultivation periods at lower temperatures. But, in order to avoid chaos, breeders worldwide must work together to reorganize the existing hybrids on the market. Equally important to the future development of the orchid industry is regulation of plant patents held independently by various countries throughout the world, along with creation of universal policies protecting the rights of breeders. With only a short history of commercial production, precise orchid cultivation techniques remain relatively undeveloped, Fig. 2. Den.

Volume 2, No. 3 2008 | ICOGO BULLETIN 13 The Global Orchid Market The worsened economic conditions around the globe certainly had a huge impact on the orchid industry in all countries. This is made even worse by the over production of young plants in all orchid-growing countries, particularly the Netherlands. It is estimated that propagators in Holland may have produced over 20 million of surplus Phalaenopsis alone. Several orchid nurseries are for sale, but sadly there were no buyers. In both Holland and Japan, an increased percentage of potted orchids were sent to auction houses where selling prices were lower than what the producers would get by selling these orchids directly to their customers. In the United States, for example, growers in California encountered difficulties selling cymbidiums this season. The market demands plants with more than two spikes. Even Cymbidium with three or more spikes had to be sold at lower than $10 a pot. This puts more pressure to grow high quality plants. One way of achieving such goal is to promote the production of double shoots from the first and second generation pseudobulbs. This would require better feeding program, earlier spacing and selection of stronger young plants at the very beginning. The market in general poised toward selling lower priced orchids in 7.5 cm, instead of the 10 cm and 12.5 cm pots. On the other hand, breeders and propagators who have carefully set their goals and strategically line up their prowuction with their customer’s needs have been doing well. For instance, the Sogo Team Company in Taiwan has engaged in breeding medium to small size plants for the European market to fit the specific needs of those markets. Rocket Farm in California imports Phalaenopsis in their original containers from Sogo by sea containers. In taking such a strategic approach toward their breeding, production, and marketing, Sogo sold out their young plants. China produced 15 million pots of Phalaenopsis in 2008. In comparison, Phalaenopsis production in 2007 was 9 million pots. Among the Phalaenopsis, 80% were the red varieties. Due to the warm climate in east and south China in August and September this year and an earlier Chinese New Year in 2009, it is estimated that perhaps 20% to 30% of the Phalaenopsis may bloom too late for the market. In one of Beijing’s whole sale market, orchids were selling for about $5 as opposed to more than $9 per pot in 2007.

In the early 1930’s, the Rod McLellan Co. was the largest gardenia producer in the world, with some 280,000 square feet of greenhouses devoted to the production of this fragrant flower for corsages. McLellan’s was called by the Saturday Evening Post as “The King of Gardenias”. The Company also raised South African heather which was used for Christmas and Easter. During WWII, the Rod McLellan Co. produced fresh vegetables for the nearby military installation at Tanforan Park. The Company started to grow orchids in 1941 to diversify its product line. At the time, there were four other orchid nurseries in the San Francisco Bay Area. J.A. Carbone in Berkeley, Avansino and Mortensen in San Leandro, Ferrari Brithers in San Francisco, and Niven and Company in Marine. In 1946, the Company purchased and imported a large number of species orchids from South America. All of these orchids were collected from the jungle. With both the use of gardenia and orchid corsages on the decline and the production costs on the rise, McLellan added three more greenhouses for blooming pot orchids and bought seedling plants from the east coast. The Rod McLellan Co. first started sowing orchid seeds from its own Cattleya hybrids in 1944. By 1953, it is known as “Acres of Orchids”. The company first cloned Cymbidium in 1966, followed by Cattleyas, Miltonias, and Oncidiums in 1968. Rod McLellan passed away in 1974. His wife Lorraine and his family continued to operate the orchid business. The Rod McLellan Co. was also the manufacturer of a potting medium called “Super Soil’. It has a rigorous orchid breeding program from which came some well known and widely grown hybrids and clones. Many clones of Colmanara Wildcat are being produced all over the world in large numbers. The relatively heat-tolerant cymbidium Gold Elf ‘Sundust’ HCC/AOS was bred and selected by the Rod McLellan Co. This clone has brilliant, lightly fragrant, and nonfading yellow flowers among the dark green foliage and a long blooming season spanning from Figure 1. Rod McLellan and his breeding teammates Paul Brecht, Austin Enright, and Robert Jones (left to right). Picture used with permission from the American Orchid Society. and May to October. The company also has an orchid boarding division. They took care of orchids that were out of bloom and deliver the plants back to their rightful owners when they bloom again for a charge. The Rod McLellan Co. was also a large supplier of cut orchids. In addition, the company has an operation in Aromas, California, where they not only produced orchids, but also has acres of Eucalyptus for making dry flowers. Due to the booming orchid market, the Company got rid of most of its Cattleyas, and remodeled the old greenhouse for increased production of Phalaenopsis. In the mid-1990’s a large greenhouses was added for producing Phalaenopsis and Dendrobium phalaenopsis. When visitors arrived at the hilltop property of the Rod McLellan Co. in South San Francisco, they were first greeted by a well laid out orchid and gift shop. In front of the shop across the parking lot and behind the shop, there were acres of greenhouses full of orchids. In 1991, the Rod McLellan Co. began purchasing Phalaenopsis from the newly funded Taiwan Sugar Corporation. Jeff Britt, a former President of the Rod McLellan Co., said that the company made excellent profits by buying in Phalaenopsis from Taiwan Sugar rather than breeding and raising their won. Taiwan Sugar was established during the Japanese occupation of Taiwan in the late 1880s. It became a state-owned company after Taiwan was reunited with the Republic of China after the Second World War. It produced and sold sugar to support the ROC’s national economy between the 1950’s and 1970’s. Due to the strong competition on the international sugar market, Taiwan Sugar had to cut down its sugar production and became diversified in its business. It has been raising cattle and hogs, engaged in cooking oil production, retailing fuel, as well as operating restaurants and many other types of businesses to generate revenue for the federal government in Taiwan. In 1988, Taiwan Sugar’s Agricultural Division was looking for means to further diversify its business and decided orchids may be a good international business because there was virtually no competition. After a thoughtful planning and consulting some university faculty specializing in orchids, Taiwan Sugar started its orchid production at an abandoned sugar mill in Shin-In, Taiwan. It also formed a Horticulture Department at its Taiwan Sugar Research Institute that had a sole mission of conducting research on and breeding of the Phalaenopsis. Selling on the international market was not an easy task. In 1990, Taiwan Sugar sold 3,500 Phalaenopsis to buyers outside of Taiwan. Since 1991, Professor Yin-Tung Wang at Texas A&M University, who then became an honorary advisor to Taiwan Sugar, helped Taiwan Sugar with their marketing and resolving their customers’ production problems in North America and Mexico. Business grew quickly. The Rod McLellan Co. became Taiwan Sugar’s largest overseas customer. The orchid business of the Rod McLellan Company was eventually bought out by Taiwan Sugar in 2003. Today, the Rod McLellan Co. contimues to operate under the name of “McLellan Botanicals” and “Taisuco America”. It no longer carries out any breeding and relies on imported orchids for production. The retail orchid and gift shop was relocated to San Mateo, but, was closed a few years later due to declined traffic.
