several applications of Bt are not used. in many (most?) fields application is not
needed at all. spraying of anything is not done unless there is an explosion of
pests in a field because spraying for a few pests is not cost effective. So most
fields of corn do not get sprayed.

having Bt in every cell of the corn means the corn borers are always exposed to the
pesticide and guarantees selection for resistant corn borers. there are ways around
this, but farmers arent doing what is needed.

If it is all about the Monarch then the choices are the
pollen of the genetically altered corn effecting one
generation of caterpillar within 200 feet of the crop
that is in it's two weeks phase of pollination and the
pollen can be washed off by rain, or having crops
treated with a BT insecticide that is designed to adhere
to the plant thus lasting longer and will need several
applications throughout the growing season causing harm
to several generations of larvae or having the crop
treated several times in the growing season with a non
selective insecticide not only possibly killing Monarch
larvae but adults and many other type of non target
insects.
