Physiology and Growth Responses of Cool Season Turfgrasses Treated With Trinexapac -Ethyl or Paclobutrazol
… (PGRs) such as trinexapac-ethyl (TE) and paclobutrazol (PAC) are often routinely applied to highly managed turfgrasses to suppress clipping production, increase sward density, and enhance color. However, reports of variability in the seasonal responses of PGRs indicate further studies are …

A study of the effects of paclobutrazol on the growth rate of fast growing tree species
… growth regulator 'Cultar' (active ingredient paclobutrazol) was applied to five trees (treated) in each species, a further five of each had the same amount of water applied (blank) and the remaining five trees of each species provided the control. All trees were pruned prior to treatment. One …

<i>Phlox paniculata</i> 'Blue Boy' and <i>Rudbeckia hirta</i> 'Indian Summer': Cultural Guidelines for Greenhouse Growth and Powdery Mildew Control
… chloride, daminozide/chlormequat chloride, and paclobutrazol were effective in controlling size of <i>Phlox</i>. During the first <i>Rudbeckia</i> experiment, paclobutrazol and uniconazole were effective in controlling plant size; in the second experiment daminozide, uniconazole and flurprimidol …

Total nonstructural carbohydrate (TNC) flux of creeping bentgrass receiving sequential applications of growth retardants
… retardants, trinexapac-ethyl, flurprimidol and paclobutrazol were treated in an initial greenhouse study but only trinexapac-ethyl was included in subsequent field and greenhouse experiments. Applications of trinexapac-ethyl (0.28 kg ha$\sp{-1}),$ flurprimidol (0.56 kg ha$\sp{-1}),$ and …

Studies With Triazoles to Alleviate Drought Stress in GreenHouse-Grown Maize (Zea mays) Seedlings
… parameters. Applications of three triazoles (paclobutrazol, uniconazole and tetraconazole) altered morphology and physiology in ways that might impart drought resistance. Paclobutrazol and uniconazole increased root:shoot ratio in laboratory studies and in the greenhouse. When compared to …

Regulation of Growth and Branching of Containerized Penstemon x mexicali Cultivars
… high and low rates of foliar applications of paclobutrazol or uniconazole resulted in growth control of the crop. Liner drench or soak applications of paclobutrazol were the most effective at reducing growth but resulted in over-regulated and stunted plants. A separate study focused on the …

Prohexadione Calcium for Turfgrass Management and Poa annua Control and Molecular Assessment of the Acetolactate Synthase Gene in Poa annua
… The plant growth regulators trinexapac-ethyl and paclobutrazol are commonly used in VA for these two costly and challenging jobs. Prohexadione calcium (PC) is an experimental chemical that inhibits the same enzyme (3ß-hydroxyalase) as trinexapac-ethyl and may selectively suppress annual bluegrass. …

Propagation, height control, and flowering of Hypoestes phyllostachya
… of ancymidol, chlormequat, ethephon, paclobutrazol, and uniconazole to inhibit shoot growth and internode elongation of H. phyllostachya were determined and found to be similar for both seed- and cutting-propagated plants. Daminozide, even at 6000 mg-liter- 1 , was ineffective. Two …

Ecology, behavior, impact, and an integrated pest management strategy for the orangestriped oakworm, Anisota Senatoria (J. E. Smith), in the urban landscape
… present in low strata. The tree growth regulator paclobutrazol significantly reduced Q. Phellos L., willow oak, growth, especially one and two years posttreatment. One year posttreatment, paclobutrazol treatments significantly slowed development and decreased survival of early instars, but the …

The Effect of Fe-sulfate on Annual Bluegrass, Silvery Thread Moss, and Dollar Spot Populations Colonizing Creeping Bentgrass Putting Greens
… with seaweed extract (12.8 L ha-1) or paclobutrazol (0.37 L ai ha-1 spring and fall; 0.18 L ai ha-1 summer) were applied March to October, 2011 and 2012. Plots receiving the highest rate of ferrous sulfate resulted in annual bluegrass infestation declines from an early trial amount of …

Nutrition and Plant Growth Regulator Rates for High Quality Growth of Containerized Spiderwort (Tradescantia virginiana L.)
… most effective rates for height suppression were paclobutrazol at 120 mgּL-1, uniconazole at 45 mgּL-1, and flurprimidol at 45 mgּL-1. The second experiment was divided into two parts. The first screened three T. virginiana cultivars for their growth response to several nitrogen (N) rates. The …
