Roundup isn’t used on crops or produce.
Its a general defoliant used to control weeds in areas where you don’t want growth.
I used to use it in green houses to keep weeds from growing into green house floor.

I beg to differ. Ever heard of Roundup Ready corn, soybeans, alfalfa, sorghum, etc?

Wrong.

The whole reason GMO crops were created was so that farmers could do "no till farming". The seeds are modified to be able to withstand Roundup. Then the fields are treated with it, killing all of the weeds. The GMO crops then can grow undisturbed.
