Great if you like weeds.
Somehow people managed to farm before glyphosate was released
Yes, RoundUp is great in small, carefully-applied quantities for fighting weeds. But farmers spray it in huge quantities on their grain crops a couple of days before harvesting. It dessicates the plants and makes them easier to harvest and ups per-acre yields. Virtually every product on the market containing American grain will show traces of glyphosate. (Buy imported pasta!)
Application on weeds is great, I use it. But spraying it directly on an edible crop to synchronize ripening needs an alternative.
