Earlier quoted context omitted.
Are there really that many innovations in how to harvest a wheat field?
Didn't they just recently start desiccating with Glyphosate at the end of the growing cycle to speed their harvest up by two weeks and putting glyphosate into food a few days harvesting it (causing a higher concentration in food than previously)?
Then, e.g. during the cereal growing phase there are regular applications of fungicide, insecticide, growth regulators and so on.
Bottom líne, if you are not buying 100% organic this is the reality of your food chain.
(Full disclosure: I do not buy organic)
