A-rest

A-Rest is the commercial name for ancymidol. It is more effective than either Cycocel or B-nine and is used at much lower rates. Concentrations applied are usually in the range of 10 to 200 ppm for foliar sprays and 0.15 to 0.5 mg per 6-inch container for substrate drenches. A-Rest readily moves through the plant and is usually used on crops where other chemicals are not effective (most notably in bulb crops) or on very high value crops (i.e. plugs). Some phytotoxicity may occur from A-Rest application (especially under high temperatures) and usually appears as necrotic spots. Poinsettias are especially sensitive to injury from A-Rest application.
