This note has reference to the correspondence: ‘Bt cotton: refuge in mixed bag’ by Muralimohan and Srinivasa. In fact, their article itself was in response to an earlier correspondence entitled ‘Bt resistance in Helicoverpa species: Indian policy needs urgent revision’ by Hanur, in which the author has advocated ‘refuge in mixed bag’. Since Muralimohan and Srinivasa have raised certain concerns and opined against the use of ‘mixed bag’, I have made an attempt to address their concerns, clarify certain doubts and
also explain the need for this approach.(Correspondence)
