Well yes, people have the right to know what's in their food, but a lot of genetically modified plants create their own pesticides and the harmful ones are often not created by the plant but by other sources. Of course not all organic farmers use the harmful ones but here are a few ones of note:

Organophosphates & Carbamates : attack the brain and nervous system

Soil Fumigants : Irritation of eyes, skin, and lungs

Pyrethroids: links to heart disease

So I see your concern about what you are putting in your body and hope this proved helpful. :D
