[Beatriz9]

The smell of fresh-cut grass is a signal of distress​

Scientifically, that amazing fragrance of fresh-cut grass is the release of enzymes as a result of stress—similar to when humans sweat when stressed. When grass is cut, "the plant signals the environment via the emission of volatile organic compounds, which are recognized as a feeding queue for parasitic wasps to come to the plant that is being eaten and lay eggs in the pest insect," says Michael Kolomiets, Texas A&M AgriLife Research plant pathologist.
