The Spray Drip Down Method is used to propagate plants from cuttings.

Take plant cuttings. Stick the cutting in media. Spray the leaves until the Rhizopon rooting solution drips down. The method has many advantages. For large or small production lots, the cuttings are rapidly and uniformly treated with the Rhizopon rooting solution. With minimum labor, there is no pre-treatment when sticking. Treatment is performed by a trained applicator. The solution is used one time. There is never cross contamination between production lots.

The Method is easy to use
Stick the cuttings in media in trays, pots, or in beds. Make up a Rhizopon rooting hormone solution. The solution contains rooting hormones that promote root formation. A fine mist sprayer is used, such as a hand, backpack or hydraulic sprayer. Boom sprayers are not used since they have limited control of the spray. Spray the Rhizopon rooting solution onto the leaves of the cuttings until the liquid drips off the leaves. If the leaves were wet from misting before treatment then use an excess of spray to overcome dilution. An excess of spray is preferred. After treatment turn on misters after the solution dries on the leaves, or about forty five minutes. Then continue your normal operations.

Let us look inside the plant leaves and see how hormones move in the plant.
This cross-section shows how the hormones in the Rhizopon rooting solution enter the plant's vascular system through the open stomata in the leaves. The plant also produces natural rooting hormones in the leaves. By polar mass flow, the Rhizopon and natural hormones move from the leaves to the basal end of the cuttings. Depending upon the cutting condition, environment, and distance, transport may take six hours. The rate of travel is not critical. Once the hormones are in the vascular system they travel to the basal end where they are stored. The plant self regulates hormone use to induce root formation. When the threshold hormones are reached at the basal end, the potential root cells are programmed to become new root cells. The Spray Drip Down Method treats the cuttings uniformly. The threshold level is achieved. Rhizopon treated cuttings form uniform roots around the base

Since cutting quality and growing conditions always differ, you should always do trials for each plant variety in your facility.
