The Miller Amendment to the Pure Food Law—the Federal Food, Drug, and Cosmetic Act of 1938—became law on July 22, 1954, with provision that its enforcement with respect to some of the new pesticide materials be delayed one year. More recently, extensions have been granted in specific instances, but the law will become fully effective October 31, 1955, at the end of the 1955 growing season. However, all other requirements of the amended law are now in effect and subject to enforcement.
