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.

Organic farming still uses pesticides.

See https://www.epa.gov/agriculture/organic-farming - "Pesticides derived from natural sources (such as biological pesticides) may be used in producing organically grown food"

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.
