What I mean by plant location is the class of GMO plants which produce 
their own insecticide systemically.  Bt corn as an example:

Bt was/is an approved organic insecticide. Before GMO corn it was 
sprayed on and would eventually wash off. With the variants of Bt GMO 
corn however, all cells in the corn plant make Bt, including the parts 
which humans and animals eat. Traces of the Bt toxin can now be found in 
most Americans and in infant amniotic fluid. I have not heard of any 
studies, but I suspect the same would be true of the animals fed this 
corn. This GMO crop has taken a relatively safe insecticide which was 
applied only to the exterior of the plant, and make it systemic 
throughout the plant. Cannot be washed off or peeled off.

There is no recognition that changing the delivery mechanism of an 
insecticide has the potential to change exposure amounts and whether or 
not it is still safe. As we have seen, it certainly changes its 
distribution and accumulation in the animals (including humans) which 
eat that crop.
