Has weed ever killed someone? - Computers & Internet

I purchase full strength roundup from places that sell fertilizers etc to farmers. I mix my own roundup per their recommendations plus a little. I fill a small eye drops bottle with my mixed roundup. I like this bottle because it has a small opening so I can squeeze out a drop at a time.. I carry the bottle of mixed roundup in my pocket, with the lid shut tight of course, and as I mow and I spot a weed I take out the bottle and place on or two drops on that weed. One drop of roundup on a leaf of a plant will kill it but I try to place one or two drops right in the middle of the plant. Roundup is fed to the root of the plant from the leaf kills the weed from the roots up. This works well because I can kill the weed without killing grass or other plants around it. Wind will not effect it because the roundup is place on the plant not sprayed on it. Roundup needs about 12 hours to work so do not water right away. Ready mixed roundup from a store may work, I have not tried it because I want to be sure the mixture is strong enough to do the job. About 4 ounces per gallon of water is recommended, I increase that to about 6 ounces. Works great.
