If any of your neighbors are growing organic corn, please talk to them
before planting. Depending on the distance and their certification
agency, your growing GMO corn may make it impossible for them to grow
The more BT corn is grown, the sooner the earworms are likely to
become resistant to BT in general. I don't know whether this
resistance is already occuring; you might look into that -- I would
think that extension agents in your county should be able to tell you
whether there's resistance in your area. Once the resistance develops,
the BT corn won't work anyway. Resistance will develop faster if the
BT is built into the corn than if you just apply it with, for
instance, a Zea-later, because the BT is continuously present when
it's built into the genetics.
I agree that, if you do decide to grow it, you should label it for
your customers; and that labeling it as "unsprayed" (which I note you
didn't say you were going to do) would be misleading: there's more
pesticide present in genetically BT corn than there would be if you
applied it with a sprayer, not less.
Have you tried a Zea-later, by the way?
