The herbicide 2,4-D mimics the plant hormone auxin and sets off a complex series of events - involving two other plant hormones - that eventually lead to the death of susceptible plants.
Grasses are much less sensitive to synthetic auxin herbicides than are dicots. That is, a much higher threshold level of auxin-based herbicide is required to elicit physiological responses in grasses versus the so-called "broadleaf" plants. So, at the doses used to kill daisies, for example, grasses are largely unaffected.

one type of grass that kills plants can be Johnson farm grass. they have poisonous roots to plants but not humans.
you offon find daisys in the grass, fileds or woods
yes like daisies and grass and pansies.
Daisies in mowed or grazed grass can benefit from increased sunlight reaching the ground due to the shorter grass. This allows them to photosynthesize more efficiently. Additionally, the disturbance from mowing or grazing can help prevent taller, competitive plants from shading out the daisies.
They eat grass
too many big words!
it kills the parts it touches
Because poison kills plants
Lots of trees and flowers like daisies,sunflowers and more
Yes, salt kills the grass in most yards. There are some salt-tolerant grasses but they are not common.
Chlorine gas
Because the acidity from the dog's urine kills the patch of grass they urinated in.
