“Monsanto is now estimated to control between 85 and 90 percent of the U.S. nursery market. This includes the pesticide, herbicide and fertilizer markets.”
“Six companies Du Pont, Mitsui, Monsanto, Syngent, Aventis and Dow control 98 percent of the world's seeds.”
“. . . in 1981 there were approximately 5,000 vegetable seed varieties available in U.S. catalogs. Today there are less than 500, a 90 percent reduction.”
