“…In India, Chaturvedi et al (2009b) discovered a phytoplasma from the aster yellows (16SrI) group that was linked to phyllody symptoms. " Madhupriya et al (2017) confirmed the association of two phytoplasma groups, aster yellows (16Sr I) and peanut witches' broom (16SrII), with 13 rose genotypes by observing regular occurrences of phytoplasma-associated symptoms such as little leaf, yellowing, internode shortening, phyllody virescence, and flower bud proliferation" (Fig. 2 pq) at IARI, New Delhi.…”

“…These results further suggested the role of these weed species as natural reservoir and transmission of the phytoplasma strain from weed to ornamental plant species through potential leafhoppers. Madhupriya et al (2017) also detected phytoplasmas in seeds from symptomatic Celosia plants associated with 16Sr I-B subgroup of phytoplasma. Aido (2017) also reported the successful transmission of chrysanthemum phytoplasma (16Sr II-D subgroup) from infected chrysanthemum plants to healthy Catharanthus roseus plant through dodder (Cuscuta reflexa R.).…”

This paper reviews the global status of phytoplasma disease associated with different ornamental crops. This paper investigated phytoplasmas, an equally important group of pathogens that severely harm the growth and marketing properties of ornamental plants, lowering their commercial worth. In this paper, number of ornamental plants was found to be infected with 'Ca. Phytoplasma' species and treatment techniques were adapted using tetracycline insecticides for elimination and emission of phytoplasmas.

In recent years, the development of the floriculture sector has received rising attention, particularly for the benefit of small-scale agricultural enterprises producing domestic seedlings of perennial ornamental plants and for export to neighbouring countries. Plant diseases, including those associated with phytoplasma infections and plant viruses, are affected by this industry, as are other sectors of the agricultural economy.In a number of commercial cut flowers and ornamental plants, phytoplasma and plant virus infection causes diseases, causing major economic losses globally.Therefore, phytoplasma and plant virus diseases are the key constraints in the production of lucrative ornamental plants and lower their quantum and quality, gaining international importance due to unspecific symptoms, different losses and complex epidemiology around the world. These disease epidemics forced the removal of several varieties of floricultural plants such as gladiolus, lily, chrysanthemum and rose from cultivation. In various ornamental plants in botanical gardens and various floriculture farms, symptoms of general yellowing as well as plant stunting, shoot proliferation, phyllody, virescence, lower cost of flowers and reddening of leaves were observed. The prevalent mode of distribution of plant viruses is vector transmission, vegetative propagation or seed, although in some cases, viruses are transmitted by mechanical contact. Begomoviruses in economically important ornamental plants, especially in the tropical and subtropical regions, are among the most dangerous epidemic-causing pathogens, but phytoplasmas of ornamental plants have been widely distributed geographically. Information on phytoplasma and begomovirus infecting ornamental plants has been addressed in this study

Following a request from the European Commission, the EFSA Panel on Plant Health performed a pest categorisation of nine phytoplasmas of Cydonia Mill., Fragaria L., Malus Mill., Prunus L., Pyrus L., Ribes L., Rubus L. and Vitis L. (hereafter "host plants") known to occur only outside the EU or having a limited presence in the EU. This opinion covers the (i) reference strains of 'Candidatus Phytoplasma australiense', 'Ca. P. fraxini', 'Ca. P. hispanicum', 'Ca. P. trifolii', 'Ca. P. ziziphi', (ii) related strains infecting the host plants of 'Ca. P. aurantifolia', 'Ca. P. pruni', and 'Ca. P. pyri', and (iii) an unclassified phytoplasma causing Buckland valley grapevine yellows. Phytoplasmas can be detected by available methods and are efficiently transmitted by vegetative propagation, with plants for planting acting as a major entry pathway and a long-distance spread mechanism. Phytoplasmas are also transmitted in a persistent and propagative manner by some insect families of the Fulgoromorpha, Cicadomorpha and Sternorrhyncha (order Hemiptera). No transovarial, pollen or seed transmission has been reported. The natural host range of the categorised phytoplasmas varies from one to more than 90 plant species, thus increasing the possible entry pathways. The host plants are widely cultivated in the EU. All the categorised phytoplasmas can enter and spread through the trade of host plants for planting, and by vectors. Establishment of these phytoplasmas is not expected to be limited by EU environmental conditions. The introduction of these phytoplasmas in the EU would have an economic impact. There are measures to reduce the risk of entry, establishment, spread and impact. Uncertainties result from limited information on distribution, biology and epidemiology. All the phytoplasmas categorised here meet the criteria evaluated by EFSA to qualify as potential Union quarantine pests, and they do not qualify as potential regulated non-quarantine pests, because they are non-EU phytoplasmas.
