Performance of certain chemicals and neem formulations against ginger shoot borer (Dichocrocis punctiferalis Guen.).

摘要

A field experiment was conducted in Nagaland, India, to study the performance of pesticides and neem formulations against the ginger shoot borer Dichocrocis punctiferalis [Conogethes punctiferalis] infesting ginger. The treatments comprised: neem oil (seed treatment); chlorpyrifos (seed treatment); mulching (mahaneem leaves); phorate (soil application); neem seed cake (whorl application); neem oil (foliar spraying); Achook (foliar spraying); quinalphos (foliar spraying). Mulching treatments gave the highest yield (164.68 q/ha) and cost:benefit ratio (1:4.87).
