Use

Hexanoic acid (HA) is a short-chain monocarboxylic acid present in strawberry (Fragaria vesca L.) and arbutus (Arbutus unedo L.), which has been described to induce plant disease resistance mainly through priming of host-defense responses. After being used as a soil drench, HA is absorbed and accumulated in the roots, and not translocated to other parts of the plants.
