SANDRA: This is Sandra, and I'm here again with Dixie to talk about Roundup. Can someone use Roundup to clear the weeds from an area before planting vegetables?
DIXIE: There are many different Roundup products available. Some are suitable to use for this purpose, and some are not. Always read the product label carefully to be sure the product has been approved for this use.
SANDRA: Will the Roundup harm desirable plants nearby?
DIXIE: Roundup products contain at least one active ingredient called glyphosate. Following proper application, glyphosate tends to stay put in the soil, so it is unlikely to harm untreated plants nearby.
SANDRA: Will the glyphosate damage or prevent growth in vegetables planted in the garden later on?
DIXIE: In the soil, glyphosate generally breaks down within days to weeks. This quick breakdown time, in addition to the way it sticks to the soil, makes glyphosate less available to plants grown in the treated soil at a later time. The product label will tell you how long to wait to plant your vegetables after using Roundup for weed control.
SANDRA: Thanks, Dixie!
DIXIE: You're welcome!
