Experiments were conducted with four kinds of flowering plants to compare one-time vs. continuous application of paclobutrazol in subirrigation water. When a crop reached the stage at which it required growth regulator treatment, four concentrations of paclobutrazol were applied via subirrigation either one-time or continuously until the crop was terminated. Based upon regression equations, concentrations resulting in 30% size reduction for one-time applications of paclobutrazol were 0.01 mg·L -1  for  Begonia  × semperflorens-cultorum  `Cocktail Gin', 0.09 mg·L -1  for  Impatiens wallerana  Hook. `Super Elfin White', 0.2 mg·L -1  for  Dendranthema  × grandiflorum  (Ramat.) Kitamura `Tara', and 2.4 mg·L -1  for  Petunia  × hybrida  Vilm.-Andr. `Plum Crazy'. Respective optimal values for continuous application were 0.005, 0.02, 0.06, and 0.4 mg·L -1 . Increasing the concentration for continuous application had a greater effect on paclobutrazol efficacy than did increasing the concentration for a single application. In a trial with impatiens `Super Elfin Salmon Blush', the paclobutrazol concentration was reduced 0%, 25%, 50%, 75%, or 100% (single application) for each successive subirrigation event following an initial application of 0.1 mg·L -1  of paclobutrazol. The 50%, 75%, and 100% reduction treatments provided similar levels of size control. Dilution was more important when the reduction rate was less than 50%. Chemical name used: (±)-(R * ,R * )-β-[(4-chlorophenyl)methyl]-α-(1,1-dimethyl)-1 H -1,2,4-triazole-1-ethanol (paclobutrazol).
