Phytoplasmas are pathogens of agriculturally important plants, including coconut, sugarcane, sandalwood, and cannabis, as well as horticultural crops like sweet cherry, peaches, and nectarines. They cause a wide variety of symptoms ranging from mild yellowing, small fruit, and reduced sugar content to death. Plant pathogen presence is very dangerous for agricultural ecosystems and causes huge economic losses. Phytoplasmas are insect-transmitted wall-less bacteria living in plants, only in the phloem tissues and in the emolymph of their insect vectors. · Phytoplasmadisease in plants can take on several different symptoms. The most common phytoplasma effects on plants resemble the common "yellows" and can affect over 200 plant species, both monocots and dicots. Phytoplasmas are parasites and pathogens of plants and insects. All known phytoplasmas infect plants and are spread from plant to plant by insects, mainly leafhoppers, that feed in the phloem tissue of the plant's veins. · Learn about phytoplasmas, unique plant pathogens spread by insects, and understand why management focuses on prevention and vector control rather than a cure. Phytoplasma is defined as a cell-wall-less, non-helical, uncultivable prokaryote associated with diseases in over a thousand plant species, transmitted by insect vectors such as leafhoppers and planthoppers. Phytoplasmadiseases are often called yellows because chlorotic foliage is a common damage symptom. Yellows of ash, elm, and lilacs and lethal yellowing of palm are important phytoplasmadiseases that so far have been reported only in the eastern United States.
