“…in any country, defining the prevalent races or pathotype structures is a prerequisite. A lot of literature is available on conventional breeding for the improvement of flower characteristics, such as big, durable, and fascinating flowers, in addition to the enhancement of quality features such as flower color, vase durability attribute, shape, and architecture and genetic engineering also showed a successful breakthrough for changing complex characters in orchids, such as novel flower color ( Chia et al, 2001 ) and increased vase life ( Chia et al, 2001 ), with the identification of specific genes involved for those characters. Although more than one hundred thousand interspecific, intergeneric, or multi-generic hybrids of orchids were developed through conventional breeding worldwide, breeding for the development of resistant varieties against Phytophthora diseases of orchids is still absent in the orchid industry.…”

Anton de Bary first coined the genus, Phytophthora, which means “plant destroyer”, viewing its devastating nature on potatoes. Globally plants have faced enormous threat from Phytophthora since its occurrence. In fact, a century ago, Phytophthorapalmivora was first reported on Dendrobium maccarthiae in Sri Lanka. Since then, members of beautiful flowering crops of the family Orchidaceae facing the destructive threat of Phytophthora. Several Phytophthora species have been recorded to infect orchids with economic loss worldwide. To date, orchids are attacked by 12 species of Phytophthora. Five Phytophthora species (P. palmivora, P. nicotianae, P. cactorum, P. multivesiculata, P. meadii) are the major pathogenic Oomycetous Chromista” rather than true fungi frequently occurred on Orchidaceae. Phytophthora palmivora (having ~32 orchid host genera in 15 countries), Phytophthora nicotianae (having ~15 orchid host genera in 16 countries), Phytophthora cactorum (having ~43 orchid host genera in 6 countries), Phytophthora multivesiculata (having 2 orchid host genera in 5 countries) and Phytophthora capsici (having 2 orchid host genera in all Vanilla growing countries) are potential destroyers of Orchidaceae. Most of them are water loving Oomycetes cause disease in moist environments (> 80% RH) at 16–28°C. In artificially constructed orchidaria, anthropogenic factors are mostly contributed to the dissemination Phytophthora diseases in addition to many other factors. Water management, clean cultivation, and agro-chemicals are the major options for effective management of orchid Phytophthora, as the eco-friendly management options like development of resistant hybrids/cultivars, biological disease management, transgenic approaches, RNAi technology remained in the infant stage. In this review, we intended to highlight the insight of Phytophthora diseases associated with the orchid disease with reference to the historical aspect of the diseases, symptoms and signs, the pathogens, taxonomy, geographic distribution, host range within the Orchidaceae, pathogen identification, molecular diagnostics, mating types and races, management options and strategies and future perspectives.

Orchids constitute the largest and most diverse group of flowering plants and are classified in the family Orchidaceae. Exhibiting significance as the most exotic and ubiquitous flowering plant, the cultivation of orchids on a commercial level is gaining momentum worldwide. In addition to its ornamental and aesthetic value, the orchid industry has successfully generated employment for people in developing countries. Recent advances in biotechnological interventions in orchids have substantially contributed to the development of exotic varieties with novel traits, not to forget the inputs of traditional plant breeding methods and tissue culture approaches. In addition, the scientific developments in orchid biology have remarkably bridged the knowledge gaps in areas of orchid classification, phytochemistry, and cultivation strategies. This has facilitated the commercialization of novel varieties, opening new avenues in the orchid industry, and their global marketing as cut flowers and artificially propagated plants. Orchids constitute the first floriculture crops that revolutionized the orchid industry; however, they also hold several challenges in the natural propagation and conservation of several species that are on the verge of extinction. International organizations like CITES have come forward to address challenges associated with illegal global trade and indiscriminate use of orchid varieties, aiming for conservation and legal commercial goals. This thematic review is one-of-a-kind in providing comprehensive insights into the emerging momentum of orchid biology and how its globalization projects to considerably impact the orchid industry in the coming times. However, it is imperative to understand the challenges in the cultivation and conservation of orchid varieties and ensure legislative guidelines both on domestic and global levels to ensure a multipronged approach to the conservation and commercialization of orchids.
