Product Description

Daminozide also known as Alar, Kylar, B-NINE, DMASA, SADH, or B 995 is a plant growth regulator, a chemical sprayed on fruit to regulate growth, make harvest easier, and keep apples from falling off the trees before they ripen so they are red and firm for storage. Alar was first approved for use in the U.S. in 1963. It was primarily used on apples until 1989, when the manufacturer voluntarily withdrew it after the U.S. Environmental Protection Agency proposed banning it based on concerns about cancer risks to consumers.[2].

It was produced in the U.S. by the Uniroyal Chemical Company, Inc, (now integrated into the Chemtura Corporation), which registered daminozide for use on fruits intended for human consumption in 1963. In addition to apples and ornamental plants, they also registered for use on cherries, peaches, pears, Concord grapes, tomato transplants, and peanut vines. On fruit trees, daminozide affects flow-bud initiation, fruit-set maturity, fruit firmness and coloring, preharvest drop and market quality of fruit at harvest and during storage.[2] In 1989, the EPA made it illegal to use daminozide on U.S. food crops, but still allow for non-food crops like ornamental plants.
