Roundup This extremely effective herbicide is now available in a dry pak. Each envelope contains just enough Roundup to make one gallon of spray material. Because it's a powder, you don't have to worry about shelf life with this product! And it's much easier to handle than liquid Roundup. Great for killing sod before digging a new bed, zapping stray weeds in the rosebed, cracks in the driveway, or around trees and fences.
