Both corms have been weevil free since the bleach treatment and even before it,I saw no weevil or larvae,only tunnels. I thoroughly checked the dead pup and its soil before disposing of it to waste for incineration,and there was no weevil or larvae anywhere. I also maintained the pots above water filled containers so that any emerging weevils wouldn't be able to change pots or go anywhere and there were no weevils to be found all those months in the water traps nor in hiding spaces below the pot. All bananas have even preventively treated with the insect pathogenic nematodes which persist in the soil and are totally effective at eradicating borers,so weevils could not possibly survive in any way,especially in such small corms! I must say I added the nematodes after the choking event so,can't know if weevils could be to blame but I saw none and no pseudostem damage. I have had choking on establishing pups before too. The bleach treatment is also a little harsh on the plants and the growing center an do funny things and grow strange leafs during the first months as it can be affected by it,especially when there are bruises on a pup and the bleach enters through them.
