What is an Herbicide?

Many people mistake an herbicide for an organic-based weed-controller that is eco-sensitive. In fact, an herbicide is a pesticide that is used to kill unwanted plants. Selective herbicides are designed to kill certain weeds while leaving the crop intact. Whether a pesticide or an herbicide, they are still poisonous chemicals that are sprayed on the conventionally grown food that you buy in the store. Like pesticides, herbicides that are applied in the U.S. are regulated by the federal government.
Below is a list of the most commonly used herbicides:
1. Glyphosate: a systemic nonselective herbicide that kills any plant material that comes in contact, EXCEPT those genetically modified crops that are altered to resist its effects. On GM crops this herbicide is used to kill the weeds.
2. Paraquat: another nonselective contact herbicide used in aerial destruction of marijuana and coca plantings. It is more acutely toxic to people than any other herbicide in widespread use.
3. 2, 4-D: a broadleaf herbicide used turf and no-till field crop production. Now mainly used in a blend of other herbicides, it is the most widely used herbicide in the world and the third most commonly used herbicide in the U.S.
