questions: asking about control of banana stem weevil 
management
select healthy sucker and plant
do not take regular crop in the same field to avoid initial infestation
ensure clean cultivation
removal of pseudo stems below ground level
trimming the rhizome
avoid growing robusta, karpooruvally, malbhog, champa and adukkar
grow less susceptible varieties like poovan, kadali, kunnan, poomkalli
use cosmolure trap at 5/ha
banana corm split trap

trap adult weevils with pseudostem chopped into small pieces
kept near infested clump at 65/ha.
soil incorporation at the time of planting: carbofuran 3 g 10g, phorate 10 g 5 g/plant.
before planting, the suckers should be dipped in 0.1 per cent quinalphos emulsion.
apply castor cake 250g or carbaryl 50g dust or phorate 10g per pit before planting also prevents infestation
severe attack dimethoate, methyl demeton may be sprayed around the collar region.
