abstract
A novel botanical cake and paste developed by ICAR-CPCRI, neem cake admixed with sand, naphthalene balls and chlorantraniliprole sachets were evaluated against coconut rhinoceros beetle (Oryctes rhinoceros) on a three-year old juvenile palms (GBGD variety) at Ratnagiri during 2016-2019. Leaf damage by the pest during pre-treatment observation ranged from 10.2% to 16.2%. Palms treated with chlorantraniliprole (0.4%) GR @ 6g per palm and botanical cake and paste @ 15 g palm^-1 registered lowest leaf damage of 7.0% and 8.5%, respectively. With respect to spear leaf, chlorantraniliprole and botanical cake and paste-treated palms recorded least damage of 8.3% and 12.2%, respectively. The study revealed supremacy of botanical cake and paste in the suppression of coconut rhinoceros beetle and is comparable with chlorantraniliprole treatment.
