Growth Regulation of Vinca minor
Multiple applications of three rates each of B-Nine/Cycocel, Sumagic, Cutless, and Atrimmec were applied to common periwinkle grown in small containers in a greenhouse to control runner growth. All plant growth regulators (PGRs) suppressed runner elongation throughout the 30-week study. However, Atrimmec at 1500 to 4500 ppm severely injured plants for up to 20 weeks, and Cutless at 30 to 90 ppm reduced the number of runners for at least 24 weeks. There were no adverse effects associated with the application of B-Nine/Cycocel or Sumagic at the rates tested, 2500/1500 to 7500/1500 ppm and 15 to 45 ppm, respectively.Abstract
