Plant Growth Regulator Strategies For Trixi

Growing Trixi baskets from Selecta First Class requires the right plant growth regulator (PGR) knowledge. Below, Selecta First Class offers recommendations for using PGRs on its different Trixi basket recipes: Plant Trixi baskets with three to four TrixiLiner per 12 inch basket. For pure calibrachoa mixes, Selecta recommends using four liners per 12-inch basket. For all other mixes, it depends on how much crop time was scheduled, but three liners is sufficient most of the time. For recipes using petunias use only three liners per 12-inch basket to avoid overcrowding. Start out warm, as recommended in the growing recommendations, until roots have established and reached the basket. Pinch a second time before plants stretch too much. If single shoots start to stretch, pinch these and keep the basket in shape, focusing on good center branching. A PGR spray application a few days after the second pinch is recommended. Use B-Nine […]

Plant Growth Regulator Developments

Sonali Padhye, an assistant professor in the Environmental Horticulture Department at the University of Florida, discusses the latest on plant growth regulators (PGRs). You’ll be discussing PGRs at Pest & Production Management Conference. What are some of the latest products available in the PGR market? Over the last few years, patents for several PGR active ingredients have expired and new PGR formulations have been introduced. The new PGR formulations that we have worked with have performed very well. There is continued interest in using Configure (Fine Americas), which contains benzyladenine (BA), to increase branching. I will be sharing some of our data at the meeting. The latest PGR introduction is ConTego (Valent USA) which contains abscisic acid (ABA) and improves post-harvest drought tolerance. I will be discussing the results from our research trials as well as a trial conducted at Shore Acre Farms in Alabama. What are some of your […]

Proper Plant Growth Regulator Use

Jim Barrett, Environmental Horticulture Department professor at the University of Florida, is one of 15 speakers scheduled to present at the 26th annual Pest & Production Management Conference taking place February 25-27 in Orlando, Fla. Barrett will be discussing plant growth regulator (PGR) use, a topic he briefly discussed recently with Greenhouse Grower as the February 25-27 conference approaches. What are the latest PGRs to hit the market and how would you rate their effectiveness? In terms of size control products, Topflor is the latest product to be introduced and we have done a great deal of work with it. Topflor is a very flexible product that can be used in a wide range of situations. It is active as both a spray and a media drench. Topflor works well on crops sensitive to PGRs and it also can be very good in situations where a lot of control is […]

Keys To Summer Plant Growth Regulator Success

The switch from spring crops to summer crops can be a challenge for growers because of increased day length and day/night temperatures. Plants grown during long days and in warm temperatures with a robust fertility program will exhibit the following: good growth and more good growth. Warm summer evenings will generally add to stem elongation on most plants. PGRs (plant growth regulators) can play a key role in reducing unwanted stretch and can help carry-over crop inventory if the weather slows sales down for a period of time. A good example would be late spring production of violas or pansies. As the weather warms up, violas can stretch and get rather loose in growth. You may find the normal rate of 2-3 PPM Paczol® (paclobutrazol) sprayed is not enough to control stretch and you may need to increase the rate to 3-5 PPM or higher depending on conditions. Using one-half […]

Getting Results With A Liner Dip

Controlling plant height is a key factor in producing a quality crop and maximizing the number of plants that can be shipped per rack. Growers often use both chemical and non-chemical height control techniques to suppress stem elongation. Plant growth regulators (PGRs) are commonly applied as foliar sprays, media drenches or sprenches (high-volume spray with runoff into the media), depending primarily on the duration of the desired response. A PGR application method that is being increasingly used by greenhouse growers is referred to as a “liner dip” or “plug dip.” This application method involves placing a plug tray in a shallow PGR solution, allowing the chemical to absorb into the growing media. After the chemical application and when plants are safe to handle, the young plants are subsequently transplanted into finish containers. A plug dip can be very effective on vigorous species and provide a moderately long-lasting response. There is […]

A Fine Fortress

Fine Americas’ most recent addition to its family of PGRs, Citadel, reduces plant height by limiting internode elongation through inhibition of gibberellins biosynthesis. The result is a more compact, marketable plant that boasts darker foliage and thicker leaves. “Citadel is truly a fitting name for the product,” says Kevin Forney, technical manager for Fine, which also offers Concise, Configure, Dazide 85 WSG, Florgib, Fresco and Piccolo plant growth regulators for the U.S. ornamentals market. “Citadel provides a refuge for plants, giving them an improved quality and helping them to grow thicker, stronger and more dense. Citadel gives both the grower and the end consumer exactly what they want–a strong, beautiful plant.” Everything from azaleas to poinsettias, geraniums to woody ornamentals, Citadel is effective on a wide variety of ornamental crops grown in commercial greenhouse containers. It is also effective on hibiscus, bedding plants and other herbaceous crops. “Citadel also increases […]

Comparing PGRs

Figure 1. Celosia (Celosia plumosa ‘Fresh Look Red’) was sprayed with either Dazide (daminozide, Fine Americas), B-Nine (daminozide, OHP), Citadel (chlormequat chloride, Fine Americas) or Cycocel (chlormequat chloride, OHP) seven days after plugs were transplanted into 4½-inch pots and grown at 68°F. Controlling plant height is an essential aspect of producing greenhouse crops. Plant growth retardants (PGRs) are often used to suppress stem extension and produce a more compact, higher quality plant. Several new PGRs have become commercially available for use on ornamental greenhouse crops to inhibit stem elongation. In Table 1 (see page 44), we have listed many of the PGRs labeled for floriculture crops with their active ingredient, trade name and manufacturer. Similar to pesticides, PGRs can be grouped according to their chemical class and mode of action. As seen in this PGR comparison table, many products contain the same active ingredient. For example, Concise (Fine Americas) and […]

Fine Introduces A New Plant Growth Regulator

Citadel, a new plant growth regulator (PGR) from Fine Americas, is designed for a broad variety of ornamental crops grown in commercial greenhouse containers, including poinsettias, geraniums, azaleas, hibiscus, bedding plants and other herbaceous and woody ornamental crops. Citadel contains 11.8 percent chlormequat chloride and reduces plant height by limiting internode elongation through inhibition of gibberellins biosynthesis. Citadel also produces darker foliage and higher chlorophyll content with greater leaf thickness. “Plants treated with Citadel have an improved quality–they are more compact, and produce a better leaf color,” says Kevin Forney, technical manager for Fine. “Citadel also increases plant durability during post-production shipping by producing plants with stronger stems. Citadel can be applied alone or tank-mixed with other plant growth regulators to produce high quality plants. On certain crops, a tank mix of Dazide 85WSG and Citadel can provide a synergistic effect that results in enhanced activity.”  For more information on […]

All Eyes On PGRs

As in every other segment of the industry, competition is on the rise in the plant growth regulator (PGR) market, especially with the emerging generic molecules coming on the market as primary tools go off patent. But more competition is good news for growers, with more options available to source active ingredients, as well as improved formulations, broadened application technology and increased technical support from companies vying for business. New patented chemistries also continue to be developed to meet market needs. To assess the situation, we asked several reputable PGR suppliers for their take on the current status of PGRs as we know them, as well as what to expect in the future.  What is your reaction to the increasing development of off-patent PGRs? Chemtura: Reasonable alternatives are typically good for the industry in general. However, too many of the same PGRs fighting for the same market can dilute product value, […]
