      • It's amazing stuff. I sprayed it on some weeds in the lawn, and it killed them but it did not kill the grass.

        Flowering plants can be divided into two groups: monocotes and dicotes. Grasses are monocotes, other plants are often dicotes. The names are derived from the anatomy of the seed (one or two cotyledons), but the two groups also differ in the anatomy of the mature plants and their physiology.

        There are selective herbicides that work on one group but not the other. I can't tell what was in the product you used, but for just one example, something that goes by the common name 2,4 D is a herbicide that kills only dicotes. If you apply it to a lawn, the grass will be unaffected but other plants will die due to the disruption of their growth process.

        It also has something to do with blade width. Kills stuff wider than a blade of grass.

      • Basically you have to aim it at the weeds.

      • I was told it was the Iron in the liquid. It won't hurt grass, destroys the weed.

      • The spray bottle was to spot kill the dandelions, one by one, day by day, and I used it up and had to refill it, I probably used too much on each but it did the job. The sprayer was for a larger patch of crabgrass and some fuzzy stuff that I have no idea what it was, which was mixed in with and crowding out good grass. So, hard to say the coverage. With the sprayer I did a patch about 6 feet by 12 feet which had crabgrass, the fuzzy stuff, and these weird little purple alien flowers. Those are all gone now. There are some bare patches of ground in that area now. I have to cut out some good grass plugs and put them in there.
        With all that I have almost half the big bottle left and still half the spray bottle.
        This is not stuff to spread all over the lawn. Some dry herbicide and spreader is the thing for that.

      • Diversity in action,it dont kill the weeds,it just fucks up the nutrient absorption of the weeds,so just like welfare and other libtarded schemes,the end result is slow painful starvation
