Dazide Pre-Plant Liner Soak Experimental Trial

Dazide is the trade name for the plant growth regulator daminozide. It is widely used in greenhouse production as a foliar spray to control excessive stretch of flowering plants. Daminozide is tied up by the root substrate, so it cannot be used as a drench. A conversation with a hydroponic grower indicated they were getting excellent control. So a trial was conducted to determine the usefulness of Dazide as a pre-plant liner soak. With these soaks, Dazide comes in direct contact with the root system. This experimental trial confirms that Dazide is actively taken up by the roots and provides growth control.
