kill it, NOW! thats a hermie, no doubt about it, i can see at least 2 different banana clusters in the pic. They will ruin the rest of your crop too if you let them. if it was a stress induced hermie the picking the male parts off wouldnt be a bad idea if you just seperated it from the others and corrected any stress it was recieving while closely looking the plant over everyday for a few weeks till it stops pushing them out. however a genetic hermie will not stop, it will keep doing it like its genes tell it to.
