its not that they have pesticides "in" it, its that they have been bred and modified to be resistant to Round Up and other pesticides...

see, when you have huge plantations like Corn, and Wheat, and Soy and such, there is no way in hell you can pay someone to go out and hand pull weeds in the fields... weeds take away from the water table and nutrients in the soil, before the actual crop gets a change to do that itself, to become the best it can be...

so what do they do?

they breed the plants to be resistant to Round Up, and other pesticides, so that they can bring in planes, or whatever means nessecary, and completely drench the crops with Round Up, which then falls down onto the weeds that they are actually trying to kill, and kills them, without killing the crop...

but, the "crop", soaks that sh!t in too, even if its resistant, all resistant means is that it wont kill it, not that its not in the root system, and throughout the fibers and cells in the plant structure...

so in a nutshell, pesticides are "in it", wether you want to believe it or not...
