Bayer Advanced is also a powerful weed killer. The product can eliminate up to 200 varieties of weeds and takes less than an hour to become rain-proof.
Another strong weed killer is Round-Up Weed and Grass Killer in the Extended Control variety. This weed killer not only gets rid of harmful plants in a lawn or garden, but protects plants for up to four months; this provides a protective barrier for crops for a whole season.
