Daminozide also known as aminohydrazine, Alar, Kylar, SADH, B-995, B-nine,[and DMASA, is a plant growth regulator,a spray Chemicals on the fruit to regulate growth, make harvesting easier, and prevent apples from falling off the tree before they're ripe,making them red and firm for storage.In addition to apples and ornamentals, peaches, pears, Concord grapes, tomato transplants, and peanut vines.It was used primarily in apples until 1989.On fruit trees, daminozide affects bud initiation, fruit set maturity, fruit firmness and coloration, preharvest fruit drop, and fruit market quality during harvest and storage.When consumed by mammals, daminozide (see structure at right) is broken down into two chemical components, succinic acid (a non-toxic general intermediate in primary metabolism and 1,1-dimethyl Hydrazine (constituent with a history of studies linking it to carcinogenic activity in animal models relevant to humans); lysis also occurs when sprayed chemical residues remain on stored fruit, at higher temperatures and longer long.In 1989, use of daaminohydrazine illegal on food crops in the United States, but allowed its use on non-food crops such as ornamentals.As of August 2022.
Mode of action
Daminozide is classified as a plant growth regulator, a chemical that is sprayed on fruit to regulate growth. On fruit trees, it will affect the germination of shoots, fruit set maturity, fruit hardness and color, and pre-harvest fruit drop, [How? ] Together, they make harvesting easier and prevent apples from falling off the tree before they are ripe; it also improves the quality of the fruit at harvest and during storage (by keeping them firm and, in the case of red apples, red in color).When diaminohydrazine residues on fruit are consumed by mammals, it is broken down into two chemical components, succinic acid (a nontoxic general intermediate in primary metabolism ) and 1,1-dimethylhydrazine ("Unsymmetrical Dimethylhydrazine", UDMH ), degradation processes also occur when sprayed chemical residues remain on stored fruit ("increased with temperature and time",components have a history of studies linking them to carcinogenic activity in animal models relevant to humans since the 1960s.
