Which symptoms is caused by phytoplasma?

The presence of phytoplasmas is associated with a wide range of symptoms including stunting, virescence, shortened internodes, big bud, little leaf, witches’ broom, phyllody, giant calyx, floral malformation, and vascular discoloration (Figure 1).

What is phytoplasma disease?

Phytoplasmas are phloem-limited pleomorphic bacteria lacking the cell wall, mainly transmitted through leafhoppers but also by plant propagation materials and seeds. Phytoplasma diseases of vegetable crops are characterized by symptoms such as little leaves, phyllody, flower virescence, big buds, and witches’ brooms.

How do you treat phytoplasma?

Methods and results: In vitro grown periwinkle shoots infected with different ‘Candidatus Phytoplasma’ species were treated with indole-3-acetic acid (IAA) or indole-3-butyric acid (IBA). Both auxins induced recovery of phytoplasma-infected periwinkle shoots, but IBA was more effective.

How do you get rid of phytoplasma?

Controlling phytoplasma diseases usually begins with controlling insect vectors. This starts with good weed removal practices and clearing brush that can host insect vectors. Bacteria in one plant can also spread to other plants, so often removal of an infected plant is necessary to contain the contagion.

Is phytoplasma and mycoplasma same?

The main difference between mycoplasma and phytoplasma is that the mycoplasma refers to pleuropneumonia-like organisms (PPLOs), which can be parasitic in humans, animals, and plants whereas the phytoplasma refers to mycoplasma-like organisms (MLOs), which can be parasitic in plant phloem tissue and some insects.

Is phytoplasma a fungus?

Phytoplasmas are economically important plant pathogens that affect annual and perennial crops, bushes and fruit trees, ornamental trees, and natural floras worldwide. All phytoplasmas are transmitted by phloem-feeding insects, mostly leafhoppers, planthoppers, and psyllids.
