Description In India covering an area of 4.9 lakhs banana fruits per hacter with total production 16.9 million
tones per annum [1]. It is one of the non-commercial plant for cultivated is one of the backyard
plantings and also commercial cultivation by private growers, and allover country local
consumption for prayer some people, and traditional poojas prilecrime as temple. In addition to
this fruits as have higher potential medical and pharmaceutical per potassium because of
cultivation of banana plant. The plant parasitic nematodes as pests of different horticultural and
field crops are responsible for an annual monetary loss of Rs. 300 cores/annum in Tamilnadu
alone. Namely 50 species of plant parasitic nematodes have been reported in association with
banana root systems [2] and are mainly responsible for controlling the banana production to
greater extend. [3, 4, 5, 6]. Keeping in view of the disturbing nature of this pest, the present study
was undertaken to examine the biodiversity of plant parasitic nematodes associated with banana
intensively grown in Thanjavur district of Tamilnadu.
Banana is one of the most important fruits crops among the different fruit crops in
the agricultural and its intensively cultivated in all over the parts of India especially in middle
part of Tamilnadu. A total number of 80 each soil and root samples were collected from various
part of Tamilnadu in Tiruchirapalli. Thiruvaiyaru, Thiruvidaimarudur, Kumbakonam,
Papanasam, Thanjavur, Orathanadu, Pattukottai and Peravurani, Talkus of Thanjavur districts of
Tamilnadu during December 2006 to March 2007. Covering a range of soil types such as clay
(32) sandy (23), alluvial (17), sandy loam (4), red soil (3), Black soil (1), were processed and
nematodes populations were assessed. In the present study revealed that the all talkus of root
lesion nematodes (Pratylechus coffeae) was the predominant species found to occur in maximum
number of root samples (42/80) and it has the highest prominence value of 48785.9, 20261.2,
54529.2, 127421.7, 53622, 49900.3, 30695.1 and 44569.3 with admiration to 8 talkus Thanjavur
followed by spiral nematodes (Helicotylenchus multicintus) root knot nematode (Meloidogyne
incognita). P. coffeae was also recorded as a predominant species from all the cultivars surveyed
and the occurrence percentage rate were, 42.5, 73, 33.3, 50, 100 and 100 with respect with
cultivars Poovan, Monthan, Karpuravalli, Pacchnadan, Red banana, and Robusta, maximum
percentage occurrence of P. coffeae was recorded from red soil (66.60%) followed by sandy
loam soil (50.00%). Analysis of the soil sample revealed the presence of 12 genera of plant
parasitic nematode.
