Bacterial diseases[edit] Coconut gone bad, the dark spots are very bitter and the whole meat has turned yellow. The first indication is a bitter taste of the water, this coconut should not be consumed. Fungal diseases[edit] Virus and viroid[edit] Phytoplasmal diseases[edit] Miscellaneous diseases and disorders[edit] Red ring disease Bursaphelenchus cocophilus (nematode) Additional reading[edit] Manimekalai, R.

WIKIPEDIA - Dépérissement foliaire du cocotier.

Le dépérissement foliaire du cocotier est une maladie des plantes provoquée par un virus qui affecte les cocotiers (Cocos nucifera) au Vanuatu. Cette maladie, connue aussi sous le nom de « maladie du cocotier des Nouvelles-Hébrides », a été longtemps confondue avec le jaunissement mortel du cocotier. Elle n'est connue qu'au Vanuatu, où elle ne touche que les variétés introduites, les variétés locales n'étant pas affectées[1]. Agent pathogène[modifier | modifier le code] L'agent pathogène responsable de cette maladie est un phytovirus du genre nanovirus, Coconut foliar decay virus (CFDV, virus du dépérissement foliaire du cocotier) dont le seul hôte connu est le cocotier, en particulier le cultivar 'Malayan Red Dwarf'. Ce virus est transmis, de manière semi-persistante ou persistante, par un insecte vecteur de l'ordre des hémiptères, Myndus taffini, appartenant à la famille des Cixiidae.

Bud rot Disease symptoms Palms of all age are liable to be attacked but normally young palms are more susceptible, particularly during monsoon when the temperature is low and humidity is very high.

In seedlings, the spear leaf turns pale and comes off with a gentle pull.The earlier symptom is the yellowing of one or two younger leaves. Black spots appear on spindle leaves. Basal tissues of the leaf rot quickly and can be easily separated from the crown. Stem bleeding Damage symptoms Stem bleeding is characterized by the exudation of a dark reddish brown liquid from the longitudinal cracks in the bark and wounds on the stem trickling down for a distance of several inches to several feet.The lesions spread upwards as the disease progresses.The liquid oozing out dries up and turns black.

WIKIPEDIA - Maladie de Tinangaja.

La maladie de tinangaja est une maladie des plantes causée par un viroïde qui affecte les cocotiers (Cocos nucifera) dans l'île de Guam. Elle est causée par le viroïde tinangaja du cocotier (CTiV, coconut tinangaja viroid), viroïde mortel qui attaque exclusivement le cocotier. Cette maladie a été signalée dans l'île de Guam dès 1917, mais n'a jamais été signalé dans aucune autre île du pacifique. Un rapport de 1961 donna à la maladie le nom d' infectious yellow mottle decline (dépérissement à marbrure jaune infectieuse).

Their effects are most severe in agrarian economies where major staple crops are grown intensively. There are no direct control measures available for most crops, and resistance is available for only a few virus diseases where good crop research facilities are in place. Control is usually attempted through modification of cultural practices, but this requires an extensive knowledge of the disease cycle of the virus, including factors such as where the virus survives, the type of vector which transfers it from plant to plant, and the time and pattern of spread. A fundamental difficulty in working with viruses is that although their accurate identification is essential, the means of achieving this relies on laboratory based procedures.
