Growth Regulator Notes (1972)


White Christmas Bush, Hibiscus, and Wedelia


In a trial with seedling Euphorbia leucocephala, the white Christmas bush, a soil drench of Cycocel at Vi gram per plant was effective in retarding growth to approximately half that of the control 5 weeks later. A spray of Cycocel at 3/10 percent (3000 ppm) was not effective; neither were sprays of 100 and 200 ppm of EL531, although the latter did cause slight retardation of internode elongation. A soil drench of EL531 at 50 mg of the chemical per plant caused the death of all the plants.
