Chrysanthemum Height Control by Ancymidol, PP333, and EL-500 Dependent on Medium Composition1,2

Year: 1982

Type: article

Abstract: Chrysanthemum morifolium Ramat. plants were grown in media with and without pine bark and treated with drenches of α-cyclopropyl-α-(4-methoxyphenyl)-5-pyrimidinemethanol (ancymidol) at 0.25 mg/pot, (2RS,3RS)-l-(4-chlorophenyl)-4,4-dimethyl-2-(l,2,4-triazol-l-yl) pentan-3-ol (PP333) at 0.25 mg/pot, or α-(l-methylethyl)-α-[4-(trifluoromethoxy) phenyl]-5-pyrimidinemethanol (EL-500) at 0.0625 mg/pot, or two 5000 mg/liter foliar sprays of butanedioic acid mono-(2,2-dimethylhydrazide) (daminozide). Foliar sprays of daminozide controlled plant height equally in both media but drenches of ancymidol, PP333, and EL-500 were not effective when pine bark was included in the medium.
