What does daminozide mean?
Daminozide is a synthetic plant growth regulator, known commercially as Alar, that was developed in the 1960s to control the growth of fruit and ornamental crops. When applied to apples and other produce, it reduces excessive vegetative growth, helps fruit set more evenly, delays premature drop, and can improve color and firmness at harvest. Chemically, it belongs to the class of compounds called succinamic acids and works by interfering with the plant hormone gibberellin, thereby slowing stem elongation. The word is almost entirely technical, appearing in agricultural science, regulatory documents, and food-safety reporting rather than everyday speech. Daminozide became a household name in 1989, when tests suggesting a possible cancer risk led to public alarm over residues in apple juice and to its voluntary withdrawal from use on food crops in the United States. Today it survives mainly as a case study in pesticide regulation and risk communication.
nounA synthetic plant growth regulator (chemical formula C6H12N2O3) that slows vegetative growth and promotes uniform flowering and fruit set, formerly widely sprayed on apples under the trade name Alar.
- A synthetic plant growth regulator used to inhibit vegetative growth and improve fruit quality and ripening uniformity, especially on apples.
"Growers once sprayed daminozide on apple orchards to keep the fruit from dropping before harvest."
"The orchardist applied daminozide in late spring to tighten up the bloom period."
"Residue testing found trace amounts of daminozide on the imported fruit."
Rarely pluralized; the word normally functions as an uncountable mass noun referring to the substance. A plural would appear only when discussing different formulations or preparations.
"Several daminozides of varying purity were tested in the trial."
Daminozide is the chemical better known as Alar — the apple spray whose 1989 'cancer scare' made it one of the most famous food-safety controversies in American history.

Etymology of daminozide
The word daminozide was coined in the mid-twentieth century as a contracted trade-derived name for the compound N-(2,2-dimethylhydrazino)succinamic acid, built from fragments of that chemical description (the 'di-' of dimethyl, 'amino', and the '-zide/-cide'-style ending common among agrochemical names). Like most agrochemical coinages, it is a modern English formation rather than a word inherited from Latin or Greek, though its building blocks draw on those classical roots shared by terms such as amine and succinate.
How daminozide is actually used
A technical term confined to agriculture, horticulture, and regulatory contexts; it entered general news vocabulary mainly through the late-1980s controversy over its use on apples. It has no figurative or informal uses.
Easily confused with daminozide
Dimethoate is an organophosphate insecticide, whereas daminozide is a plant growth regulator that affects growth rather than killing insects.
