Pesticide is any substance used to kill pests. These might be insects, plant pathogens, weeds, or other organisms harmful to cultivated plants or protected species. Pesticide use has increased significantly over the last few decades, with world pesticide production increasing (after 2000) at about 6% per year. The crops with the most pesticide use are cotton, maize (corn), and oilseeds. Worldwide, 67 countries used 210 million kilograms of pesticide in 2000 — a dip from the 272 million kilograms in 1990. Over 90% of the pesticide used in the United States is targeted at plants considered weeds. The most commonly used herbicide in 2010 was glyphosate (Roundup). In the U.S., more than 80% of all herbicides are sprayed on corn and soybeans. Pesticides are chemicals used to eliminate or reduce populations of unwanted pests. Most pesticides are intended specifically to kill, but others have economic or cosmetic uses, such as plant growth regulators.
