Monsanto Co. is based in St. Louis, has dominated the market for genetically enhanced seeds for more than a decade, particularly in the U.S., where everything from corn flakes to soda and beef are often produced from crops that use technology first developed by Monsanto.
Monsanto makes biotech-enhanced seeds, for corn, soybeans, cotton and other agricultural staples. These yield-boosting seeds are designed to resist insects and tolerate herbicides, allowing famers to wipe out weeds without harming crops. Some of the company's best-selling products, including corn seeds, feature extra traits to help crops weather droughts.
The company also sells conventional seeds for tomatoes, carrots and onions.
Monsanto sells herbicides for killing weeds on farms, golf courses, gardens and other green spaces. Its chief product is decades-old weed killer Roundup. It dominated Monsanto's business when it primarily sold chemicals, and remains a billion-dollar seller annually, though sales have declined in recent quarters due to generic competition and safety concerns of European authorities.
Monsanto also licenses traits of its genetically modified seeds to other companies for sale under their own brands.
