If anything, food supply in the past 20 years uses a lot less pesticides and herbicides: look at the rise of organic sections in any supermarket.
Since 2000 organic food went from niche to mainstream.
Almost all the pesticides you eat are naturally produced by plants, so I dispute your assertion. Plant extracts light up the Ames test for mutagens.
Organic farming still uses pesticides.
