Phytoplasma-associated diseases are a major needs of this branch of the plant pathology and limiting factor to quality and productivity of many challenges all over the world. Different aspects of economically important agriculture crops worldwide. phytoplasma-associated diseases are covered: detection Annual losses due to phytoplasma diseases in many methods and new disease reports worldwide, crops vary, but under the pathogen favorable conditions epidemiology and management, insect vectors, they always lead to disastrous consequences to farming phytoplasma-host interaction and omic applications, communities. mixed infection of phytoplasmas and other pathogens and quarantine relevance of phytoplasma associated The IPWG group born in Bologna, Italy, in 2007 is the diseases. These topics will provide an authoritative forum for sharing information and strength and/or scientific backdrop for informed discussions and debates built new and more intense interactions among on recent achievements on phytoplasma research and participants.
