Diseased palms show extensive root rot. Coconut Neera is the natural sap of the mature coconut palms rich with all essential nutrients, minerals and vitamins for human health. This viral-like disease is spread by leaf hoppers, appearing with symptoms such as blackening of the inflorescence, pre-mature nut drop, yellowing and death of mature fronds from the bottom upwards. Keywords: Clonal fidelity, coconut, in vitro regenera-tion, rachillae. As a therapeutic agent, gentamicin imparts direct toxicity to kidney, resulting in acute tubular necrosis, glomerular and tubulointerstitial injury, haemodynamically mediated damage and obstructive nephropathy.There exists an increasing demand for safe and natural agents for the treatment and/or preventionofchronic nephrotoxicity and pathogenesis of kidney diseases.

Other kinds of coconut tree problems include diseases. The canopy of the coconut in the center is wilted and necrotic due to a trunk infection by Thielaviopsis paradoxa. Obvious yellowing of leaves then occurs from the bottom of the crown up. Lethal yellowing is a devastating disease caused by different groups of phytoplasmas that affect around 40 palm tree species and is now considered the main coconut disease in the world (OROPEZA et al., 2011; MYRIE et al., 2012). Usually they found protected by silken web. The larvae feeds on under surface of leaves. The fungus rots the trunk tissue from the outside to the inside. The crown size is reduced and later, One recently selected cultivar, the 'Maypan', has been bred for resistance to this disease. The immature inflorescence (spadix) is covered in spathes. Oldest leaves of palm turning yellow and wilting; reddish-brown rot in bole tissue; destruction of root system, Some grasses such as Bermuda grass have been reported as alternative hosts fro the fungi.

The use of inflorescence explants Coconut tissue culturists were initially interested in the use of immature coconut inflorescences as explants because they contain meristematic tissue, which was encouraged to form callus tissue with the addition of an auxin to the culture medium. Asian Pac J Trop Med. Lethal yellowing disease infects coconuts in phases. Next the inflorescences (flower clusters) will blacken as they rot. Serious disease after monsoon and during summer; Sunken black or dark brown lesions on rachis ; Lesions coalesce resulting in drying of rachis from tip downward ; Inflorescence drys extensively resulting in severe button shedding and immature nut fall . 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). The later stage larvae feeds on both upper and lower epidermis of leaves. Initially, gentamicin treatment significantly (p<0.05)reduced thelevels of antioxidant enzymes (SOD, CAT, GPx) and GSH and increased (p<0.05) the levels of creatinine, uric acid, urea, inflammatory markers (nitrite, IL-6, TNF- α, iNOS) and lipid peroxidation.
