Roundup is not persistent in the soil. You can lay your sod one week after spraying the weeds. The herbicide will get into the growth of any plant it touches, not anything the chemical does not touch. I don't know of a pre-m herbicide that controls germination of any weeds likely to grow this time of year. Pre-m only prevents weed seeds from germinating.
1. Take emergency contraception as soon as possible. If youâve had unprotected sex and are concerned that you could get pregnant, take the morning after pill, which is also called emergency contraception, as soon as you can. In most cases, you can take the morning after pill up to five days following unprotected sex. The morning after pill may not have any cost, or a clinic may price it on a sliding scale for those that can't afford full price. 2  You will be asked about your income and insurance to determine your fee. 3  Most universities have a health center that may offer emergency contraception.
