“…If crop sensitivity was unknown, tank mixing B-Nine and Cycocel may help growers enhance their chances for effective height control. Certain crops that are unresponsive to one PGR may be highly responsive to another with a different mode of action (16,27). A species that is not responsive to either chemical should not be responsive to a tank mix (5,11,17).…”

Coreopsis verticillata ‘Moonbeam’ and Rudbeckia fulgida ‘Goldsturm’ were sprayed with tank mixes of B-Nine and Cycocel in all combinations of 0, 2500, 5000 or 7500 ppm B-Nine and 0, 1000, 1500 or 2000 ppm Cycocel. B-Nine was more effective in controlling height of both cultivars than Cycocel or B-Nine/Cycocel tank mixes. B-Nine alone suppressed height of coreopsis 26-52% (over all concentrations and all data collection dates), in contrast to a 17–41% height suppression when B-Nine was combined with Cycocel. Cycocel alone suppressed height of coreopsis 6–16% over all concentrations and data collection dates. B-Nine suppressed height of rudbeckia 20–40% over all data collection dates, while Cycocel suppressed height of rudbeckia only in the last two weeks of data collection (10 and 12% at weeks 8 and 9, respectively). Tank mixes applied to rudbeckia were not as effective as B-Nine alone for height suppression. Flowering of coreopsis was delayed 6 days by B-Nine and 12–14 days by tank mixes of B-Nine and Cycocel; Cycocel accelerated flowering up to 5 days when used alone. Flowering of rudbeckia was delayed up to 9 days with increasing B-Nine concentrations but was unaffected by Cycocel alone or tank mixes of B-Nine/Cycocel. No phytotoxicity was observed at the concentrations used.

“…Retardants also improve stress tolerance, green color in foliage, and postharvest [Sharma et al 2011]; however, the type of species, crop, application method, and environmental conditions must be considered since they may affect this type of growth regulator [Khangoli 2001]. Zizzo and Fascella [2000] pointed out that the use of B-Nine in Tulbaghia violaceae was favorable for stem growth, but not for optimal flower development. Kelly et al [2004] argued that the use of B-Nine in Euphorbia pulcherrima and Viola wittrockiana at low concentrations was optimal for good quality flower development.…”

Daminozide (B-Nine) it is a plant growth regulator, is translocated from the leaves to the stem to avoid elongation and produce more compact plants and uniform growth and vigor. For the cultivation of Lisiathus the information of the damonizide application is scarce despite of great marketing potential, so the objective of this study was to evaluate the effect of daminozide on the vegetative growth and flowering of Lisianthus grown in pot. Granulated Lisianthus seeds were germinated and transplanted into pots under nursery conditions. Three foliar applications of daminozide were realized; two applications in vegetative stage and one in flowering, adding three concentrations in each of them (0.5, 1.0 and 1.5 ml L–1) were used and water was applied as a control during the vegetative and flowering phases. The applications of daminozide at 1.0 and 1.5 ml L–1 were optimal for the vegetative development in Lisianthus (plant height – 15 cm, size of the internodes – 2.5 cm, number of branches – 3, width and length of the leaves – 3 cm and 6.5 cm), while the dose of 0.5 ml L–1 was favorable for all flowering stages (beginning of flowering – 182 buttons, sepals closed and larger than the petals – 53), visible petals larger than the sepals – 25, floral opening and full flowering – 3 flowers per plant). Based on these results, the application of B-Nine at low concentrations (0.5 and 1 ml L–1) is recommended for the development of Lisianthus in pots.
