Greenhouse trials were conducted on potted poinsettias in the fall of 1966 at the Paul Ecke Ranch, San Diego County, with the following objectives: (1) to compare the standard rates of the growth retardantes, 2-Chloroethyltrimethylammonium choride (Cycocel) used as a pot drench and N-Dimethylaminosuccinamic acid (B-Nine) applied as a foliage spray; (2) to compare the two retardantes when both are used as foliage sprays; and (3) to determine possible injury resulting from two spray applications 10 days apart.
