Can’t see how this would be beneficial. All you are doing is killing the leaves and not the roots . But, I believe it would be a great tool fighting tick infestation.
@ctb2814 if you catch the weeds at thread stage you can destroy the energy of the root unless it's like crabgrass. On older weeds like these you have to flame them several times. It also helps to destroy the weed seeds from year to year
