Daminozide (Alar)

Daminozide is a chemical compound primarily known as a plant growth regulator. Its most common trade name was Alar. It was widely used in agriculture, particularly in the 1960s through the 1980s.

Primary Uses & Functions:

Apple Growth Regulation (Most Famous Use):

Improve Fruit Quality: It was primarily applied to apple trees to synchronize ripening, promote uniform red color, and prevent pre-harvest fruit drop.
Enhance Storage Life: It made apples firmer, which reduced bruising during harvest and transportation and allowed for longer storage.

Other Agricultural Uses:

Used on cherries, peanuts, concord grapes, tomatoes, and some ornamental plants.
Functions included stunting stem growth to produce sturdier, more compact plants (e.g., in potted flowers like poinsettias), delaying flowering, and improving stress tolerance.

Mechanism of Action: Daminozide works by interfering with plant hormones (gibberellins), slowing down cell division and elongation in plant stems.

Health Concerns and Controversy:

Daminozide became the center of a major public health and environmental controversy in the late 1980s. The key issues were:

Carcinogenicity: The main breakdown product of daminozide is unsymmetrical dimethylhydrazine (UDMH), which was found to be a potent carcinogen in animal studies (causing tumors in mice).
"60 Minutes" Report (1989): A famous CBS news report titled "A is for Apple" highlighted the cancer risks, particularly to children who consume more apple products (like juice and applesauce). This sparked widespread public alarm and a consumer boycott.
EPA Assessment: The U.S. Environmental Protection Agency (EPA) classified daminozide as a "probable human carcinogen" based on the animal data.

Regulatory Status and Current Use:

Voluntary Withdrawal (1989): Facing immense public pressure and regulatory action, the manufacturer (Uniroyal) voluntarily stopped selling Alar for food crops in the United States in 1989.
EPA Ban (1992): The EPA subsequently banned all food uses of daminozide in 1992 due to unacceptable cancer risks. The ban remains in effect today.
Legacy: The Alar controversy is a landmark case study in consumer advocacy, food safety regulation, and the power of media. It significantly increased public awareness of pesticide residues in food and is often cited as a driving force behind the organic food movement.
Limited Non-Food Use: It is still approved for very limited non-food uses, such as on bedding plants and ornamentals (e.g., potted chrysanthemums) in some countries, under strict regulations. It is not used on any food crops in the U.S., EU, and many other nations.

Summary:

Daminozide (Alar) was a plant growth regulator used mainly on apples to improve appearance and shelf life. Its use on food crops was effectively banned in the early 1990s after it was deemed a probable carcinogen, following a major public health scare. Its history serves as a critical lesson in agricultural chemistry and food safety regulation.
