For many people this may be the first or even the only option considered when weed control is mentioned. Herbicides are so widely used in our culture that many people don't even consider alternatives. Others consider herbicide use to be one of the most serious environmental problems facing the world today. Most land managers and weed control specialists stand somewhere in between. Herbicides can be an effective tool for weed management but when misused they can cause serious environmental problems and can also be serious health hazards for both applicators and other individuals who may come in contact with herbicide residues.

Herbicides which can be translocated through the roots of the plant are the most effective herbicides for plants which spread by rhizomatous root systems. Here is an animated look at how these herbicides work.
Spray droplets contact the surface of the leaves where they are absorbed. The herbicide is translocated by the plant throughout its root system before the plant dies. In some instances high rates of herbicide can actually reduce control by causing the above ground portions of the plant to die before the herbicide has been translocated throughout the root system. These types of plants can often regrow from very small portions of untreated roots.
