My first Question is: I have a product called total vegitation Killer 101, and i wondered if it would be ok to spray around trees. The trees are about 10 years old. The product does contain 2-4-d. And nothing is supost to grow for a year. The product comes in a 5 Gallon can and it is diluted 10:1 It runs about 168.00 for the five gallon can. My second question is: If You spray weeds and grass with deisel fuel will that kill the root or will that come right back.
