Since I read several articles about how Roundup is now in genetically modified seed corn, I buy only organic corn products, such as in cereal, canned corn or chips. Mary Jane Butters of "Mary Jane's Farm" has written about this. The man next door is in love with roundup, yet he thinks ivy is a desirable plant. He still can't figure out why the roses planted at the fence line posts died. They planted, then sprayed all around with roundup. There is not a day here in our SW WA area that there is not a breeze.
