Plant Growth Regulator Update

To help you finish up poinsettia production and move into spring, we’ve asked the leading technical people at companies who market plant growth regulators (PGR) to keep us current on the latest product developments and strategies. OHP recently acquired the specialty product line from Chemtura Corp., which includes B-Nine WSG and Paczol. “Both are long-time proven PGRs and have a proven track record for delivering growth control and improved crop qualities,” says OHP’s Technical Services Manager David Barcel. “These two materials, combined with the OHP brand Cycocel, will provide growers with most all of their growth control needs for greenhouse and nursery crops.” Fine Americas has added another PGR, Configure, to its arsenal. Configure increases lateral/basal branching and promotes flowering in certain ornamental crops and reduces overall plant height. The active ingredient is N-(phenylmethyl)-1H-6-amine. It is registered for use on: - Christmas cactus (schlumbergera) to promote vegetative branching and increase number […]

Information Is Power

With so many factors going into selecting the right plant growth regulators (PGRs) including temperature, amount of growth control needed and application method, it can be difficult to choose the right method. With its launch of Paczol in late fall 2005, Chemtura created the PGRx Prescription Growth Control program, which offers solutions to the growth control needs of virtually all ornamental plants grown today. “With the new PGRx program, growers will have access to the most extensive, first-hand use and rate information on the market, plus it will continue to generate new PGR information for growers to put into practical use in their programs.” says Steve Jedrzejek, Chemtura’s commercial manager, specialty products. This first-hand use and rate information is the result of Chemtura’s investment in in-house and university trials involving PGRs, plus practical use in the field. By conducting trials at key commercial grower locations, Dave Barcel, a 10-year Chemtura […]

Plant Growth Regulators And Perennials

Fine Americas Inc., a producer of plant growth regulators, has published a new product guide, Using Piccolo With Herbaceous Perennials, by Dr. Joyce Latimer of Virginia Tech. This guide is a resource tool for growers in search of new plant growth regulator alternatives for herbaceous perennial crops. The 40-page, full-color publication serves to introduce growers to Piccolo for use in producing a wide range of herbaceous perennials. The guide illustrates Piccolo’s effect on herbaceous perennial crops through studies conducted by Dr. Latimer. The guide also provides growers with general use guidelines on Piccolo applications for more than 90 different varieties of perennials. Piccolo contains 0.4 percent paclobutrazol and works by reducing internode elongation through the inhibition of gibberellin biosynthesis, generating more compact plants. Piccolo enhances the quality of perennials, bedding plants, flowering and foliage plants, bulb crops, perennials and woody ornamentals, making them better able to withstand handling and transportation, easier […]

Maximizing Marketability

Fine Americas, Inc., has introduced Configure plant growth regulator, a product positioned to help growers produce fuller, more marketable plants with better blooms. Configure increases lateral/basal branching and promotes flowering in certain ornamental crops. Applications of Configure will also reduce the overall height of the plant.

Configure contains the first registered 2 percent N-(phenylmethyl)-1H-purine-6-amine and is registered for use on:- Christmas cactus (Schlumbergera spp.) to both promote vegetative branching and increase the number of flower buds under reproductive conditions; Hosta spp. To promote lateral growth of finished plants by inducing the outgrowth of axillary and rhizomic buds and to increase offsets during propagation; and Purple coneflower (Echinacea spp.) to increase the number of branches. Configure comes in a concentrated, ready-to-mix formulation and […]

Rising To The Top

Many plant growth regulators (PGR) enter the market with a sharp learning curve, but Topflor, the newest PGR from SePRO Corp., is an exception. In addition to quick adoption for growers experienced with using PGRs, Topflor has a very wide product range. Its unique activity allows growers to control even the most vigorous varieties while providing proper control for slower-growing crops. Topflor became available in March and contains the active ingredient flurprimidol, the newest PGR chemistry to be introduced to U.S. growers of containerized ornamentals in more than a decade. The chemistry has been used successfully by European growers for many years to produce very high quality plants, according to Shane Barney, marketing manager of turf and ornamental products for SePRO Corp. Barney says Topflor’s uptake is more efficient than paclobutrazol, which results in lower application rates needed to achieve optimum results. “Topflor is highly active through plant roots and stems, […]
