Can 75% alcohol directly spray flowers to kill insects?

75% of medical alcohol is mainly used for skin disinfection. High concentration of alcohol is harmful to plants. If 75% alcohol is sprayed directly on plants, the cells of plants will be seriously dehydrated and the plants will be burned. Generally speaking, spraying flowers with wine can kill insects, and green leaves refer to beer, not medical alcohol.
