Grass that grows in undesirable locations, such as between the cracks of a sidewalk, can be killed with chemicals called non-selective herbicides. Every herbicide, even ones with the same active ingredient, can have different strengths. Therefore, purchase herbicides in a ready-to-use container for easy use.
Herbicides applied directly to the soil surface are carried down into the root system with rainfall or watering. The chemicals kill the roots when they come into direct contact with them. Chemicals that work in this way include bromacil, hexazinone and tebuthiuron.
