Abstract
Studies were conducted at Coconut Research Station, (TNAU), Aliyarnagar d&ring 2000-2001 to find out the efficacy of selected chemicals and botanicals against coconut rhinoceros beetle in young coconut palms. 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.
