Coconut inflorescence sap (neera) is the sweet, oyster- white coloured sap collected from the immature coco- nut spadix (inflorescence). Fungi will colonize young, wounded or weakened tissues; disease emergence favored by high rainfall and high humidity. Initially they feed on the lower epidermis leaving the upper epidermis intact. As the coconut tree is propagated by seed, they are subjected to some variations which can be distinguished in the trees, fruit… its inflorescence carries both male and female flowers.

The insect is quite common in high wind areas. Yellow leaf disease. THE coconut palm is one of the most important cultivated palms in … The mites spread through the wind. Stem bleeding on a coconut trunk. Coconut varieties are classified into four groups according to their mode of reproduction: Type I (strict allogamy): Short female phase with no overlap with the male phase of the same inflorescence or with the male phase of the following inflorescence. Disease symptoms: Yellowing of tips of leaflets in 2 or 3 leaves of outermost whorl. Flattened oval to round disc-like insect covered in waxy substance on tree branches; insects attract ants which may also be present; insect colony may also be associated with growth of sooty mold due to fungal colonization of sugary honeydew excreted by the insect; symptoms of direct insect damage not well documented but trees may exhibit symptoms of cocoa swollen shoot (see disease entry). Harvesting of Neera from the spadix of the palms without disturbing the physiology of the tree has a lot of potential at the industrial scale.
