[C][Branch1][Ring1][C][Cl][P][=Branch1][C][=O][Branch1][C][O][O]"}, {"from": "gpt", "value": "The molecule is the word\u2019s most widely used plant growth regulator. It is manufactured by Rh\u00f4ne-Poulenc (Bayer Crop Science). Upon metabolism by the plant, it is converted into ethylene, a potent regulator of plant growth and maturity. It is often used on wheat, coffee, tobacco, cotton, and rice in order to help the plant's fruit reach maturity more quickly. Cotton is the most important single crop use for ethephon. It initiates fruiting over a period of several weeks, and enhances defoliation to facilitate and improve efficiency of scheduled harvesting. Ethephon also is widely used by pineapple growers to initiate reproductive development of pineapple. Ethephon is also sprayed on mature-green pineapple fruits to degreen them to meet produce marketing requirements. The toxicity of ethephon is actually very low, and any ethephon used on the plant is converted very quickly to ethylene."}]
