Abstract:

The frontline demonstration was conducted to evaluate the efficacy of insecticide Imidachloprid and neem cake against root grub infesting arecanut at Malnad areas of Shivamogga district, Karnataka during 2012 to 2016. The results revealed that in demonstration plots the combined application of Imidachloprid + neemcake application for root grub over five years constantly resulted in lower incidence compared to farmers’ plots. In the treated gardens the trees showed the symptoms of untapering towards tip, larger internodes, greenish colored healthy and normal sized leaves and the gardens were completely free from root grub infestation. The highest yield was recorded in demonstration plots (10.20 q/ha) as compared to farmers’ plots (7.81 q/ha), registering an increase in yield of 27.17 per cent over farmers’ practice. As far as the economics is concerned, the demonstrated technology gave the highest cost benefit ratio (1:4.10) as compared to farmers’ practice (1:3.69). Group meetings were conducted to spread awareness among neighboring farmers about the time and method of application of treatments for the effective management of arecanut root grub. Farmers were impressed with the higher yield and root grub free gardens.
