Florel

Florel is the commercial name for ethephon phosphonic acid. The material is absorbed by the plant tissue, and due to a change in pH, releases ethylene. Florel is used to promote flower bud abortion and vegetative branching in crops. Although it is used in many situations, it is most commonly used where vegetative cuttings are being produced and in hanging basket production. Florel is applied as a foliar spray at concentrations of 1000 to 4000 ppm. Florel may also be used to promote flowering in bromeliads.
