The results revealed that placement of phorate 10G @ 5gm in two perforated sachets in two inner most leaf axils for 2 times at 6 months interval significantly reduced the leaf damage from 28.18 per cent to 210 percent at 12 months after treatment. This was followed by placement of 3 naphthalene balls in 3 perforated sachets and leaf axil filling of Neem seed kernel powder + sand @ 100 + 100 gm reduced the leaf damage upto 4.66 and 4.78 per cent respectively. Leaf axil filling of Sevidol 8G + sand @ 25 + 200gm and placement of carbofuran 3G @ lOgm in 2 perforated sachets were on par in reducing the leaf damage. Application of Lindane +1.3% dust, Endosulfan dust and Pungam seed powder proved to be the least effective in containing the leaf damage. Leaf axil filling of common salt + sand did not have any influence on reducing the leaf damage caused by rhinoceros beetle.Item Evaluation of Coconut hybrid, ECT x BSR tolerant ect in basal stem rot sick soil(2005-09) Karthikeyan, G.; Karpagavalli, S.; Natarajan, C.Item Evaluation of pheromones in the management of red palm weevil on coconut(2005-02) Muthiah, C.; Natarajan, C.; Radhakrishnan Nair, C.P.Item Genetic improvement of coconut (Cocos nucifera L.) in Tamil Nadu(2003-05) Ganesamurthy, K.; Natarajan, C.; Packiaraj, D.; Rajarathinam, S.; Khan, H.H.Item Intercropping system in coconut for East Coast region of Tamil Nadu(2010) Natarajan, C.; Subramanian, P.S.; Mohandas, S.Item Performance of ECT x BSR Tolerant ECT Hybrid Coconut In High Inoculum Basal Stem Rot Soil of Tamil Nadu(2006) Karthikeyan, G.; Raguchander, T.; Natarajan, C.; Arulraj, S.Item Performance of TxT Coconut (Cocos nucifera L.) hybrids in Tamil Nadu(2006) Natarajan, C.; Yuvaraja, A.; Vaithilingam, R.; Ganesamurthy, K.; Arulraj, S.Eight TXT hybrids and seven parents were studied for their yield performance and manifestation of heterosis for yield of nuts and nut characteristics. Among the hybrids, three showed positive heterosis for yield ofnuts and four showed positive heterosis for yield of copra. Manifestation of heterosis also differed significantly for nut characters. Hybrid combinatio~s Laccadive Ordinary Tall X Cochin China Tall and Laccadive Ordinary Tall x Philippines Ordinary Tall were superior for yield of nuts and copra per palm/year. The study revealed the possibility of identifying certain TXT hybrid combinations giving high yield.Item Screening of Coconut Germplasm for Tender Coconut Water(2002-12) Ganesamurthy, K.; Natarajan, C.; Vaithilingam, R.; Giridharan, S.; Khan, H.H.Item Variability and heterosis in spathe traits of coconut (Cocos nucifera L.)(2010-08) Jayabose, C.; Ganesh, S.; Natarajan, C.; Arunachalam, V.; Arulraj, S.
