Product Overview

Sumagic Plant Growth Regulator is designed to promote denser plants with increased shelf life. It features a unique formula which provides an excellent way to keep plants from overgrowing to maintain their marketability. This growth retardant works through reduction of internode elongation by inhibiting gibberellin biosynthesis to maintain a more consistent compact and profitable plants. It also helps produce better plant qualities which include higher chlorophyll content, thicker leaf, darker color, stronger stem, and increased water retention. This liquid formula will not cause phototoxicity when used as directed according to the label. May be applied as a foliar spray, drench, bulb or cutting Dip, and as a pre-plant application to the soil surface. It is recommended for use in commercial greenhouse, lathhouse, and shadehouse on ornamentals and fruiting vegetable transplants. Available in a 1-gallon jug.

Sumagic may be applied through four different application methods: Foliar Spray, Drench, Bulb or Cutting Dip, and as a Pre-Plant Application to the Soil Surface.

Sumagic is an extremely active plant growth regulator. Caution must be exercised in measuring, diluting, and applying Sumagic. Excessive doses will result in severe growth retardation and possible adverse effects on flowering, plant appearance, quality and marketability.

Differences in plant response to Sumagic due to plant surface area in relation to soil surface area are possible. Extreme temperatures can influence plant response to Sumagic.

It is recommended that Sumagic be applied during morning or late afternoon hours, or when plants are not under environmental stress. Sumagic retards elongation almost immediately after application. Assessment of rate response for most species can be made within five to seven days after treatment. If desired results are not evident, reapplication or an increased rate may be warranted.

Temperature and light level are important factors in determining the proper application rate of Sumagic. In general lower rates and fewer applications are required for plants grown in lower temperatures/less light intensity and higher rates and/or more applications are required for plants grown in higher temperatures/higher light intensity. Data from experiments used to make recommendations found in this label were generated in northern and southern climates for most plant species.

Cultural practices may affect the plant(s) response to Sumagic. Plants which are grown at close spacing or in small pots and using high water and fertility levels may require an increase in the amount of Sumagic needed. The media in which the plants are grown can influence the effectiveness of plant growth regulator drench applications. Sumagic drench applications will be less active in growing media with a high amount of pine bark.

Different varieties or cultivars within a given plant species may require a higher or lower rate of Sumagic. Taller, more vigorous varieties generally require more chemical than do the shorter, less vigorous varieties. Growers should consult with plant and seed suppliers for vigor and other growth characteristics for newly released varieties.


Apply foliar applications with standard spray equipment. Effective dose is strongly dependent on application volume. Plant response can vary if a given rate is applied at different spray volumes. Uniformity of spray is equally important. Except where noted, uniformly apply 2 qts of finished spray solution to 100 sq ft of bench area.

Applying foliar applications of Sumagic to plants on water collectors or on sub-irrigation benches may lead to more growth reduction than desired due to Sumagic being taken up through the soil with the irrigation water. When making applications under these conditions, the rate of application may need to be reduced.


Sumagic may be applied to the soil surface just prior to planting plugs. A pre-plant soil surface spray often results in more uniform plant height. Sumagic is readily absorbed by roots and translocates in xylem tissue to the plant terminals. In general, only one half or less of the typical foliar spray rate will be required when spraying Sumagic on the soil surface prior to transplanting plugs. The required rate will vary across plant species, and the grower should conduct trials on a small number of plants under actual use conditions to determine the optimum rate. Soil media can strongly influence response to Sumagic. Soil media high in pine bark may require higher rates. Research conducted to support this application technique was conducted under normal surface irrigation, not sub-irrigation.


Drench application allows a more uniform application of Sumagic resulting in more uniform height control. Sumagic is readily absorbed by the roots and translocated in xylem tissue to terminals. Growing media should be moist but not wet at time of drench application. This may be achieved by watering the day before application. Response may vary if the media is too dry to allow for even distribution at application.

Generally, 4.0 fl oz of drench solution is required for a 6 inch pot. For larger or smaller pots, adjust volume up or down, depending on pot size. A suitable drench volume is application of enough solution to achieve total run through of no more than 10%, assuming that soil media is properly moist prior to application (example: if 4.0 fl oz of drench solution is applied, no more than 0.4 fl oz should run through the bottom of pot). Growers should determine proper volume per pot on pot sizes other than 6 inches by conducting small trials on a few plants with water.


Bulb soaks are an effective and economical method of reducing height of bulb crops. This method allows for a uniform application of Sumagic prior to planting. In general, bulbs are soaked in a solution of Sumagic for 1 to 5 minutes and then planted. Please see section titled ‘Bulb Crops’ for further information.


The rates recommended on this label are rate ranges and should be used only as a guideline.

Optimum Sumagic rates depend on the desired final size and many physical and environmental factors. Specific growing practices such as watering potting media, fertilization, and temperature and light conditions will also affect the growth response to a given rate.

When using Sumagic on plants not specifically listed on the label, use the following table as a guideline to determine a starting point. To determine optimum use rates, conduct trials on a small number of plants under actual use conditions using the lowest recommended rates.


  • Do not apply Sumagic under conditions that can cause drift to food, forage or other plantings that might be damaged or the crops thereof rendered unfit for sale, use or consumption.
  • Avoid spray drift onto non-target species.
  • Do not apply directly to soil or to plants/pots in direct contact with soil in Greenhouses, Lathouses or Shadehouses with soil flooring of high porosity and low organic content.
  • This product has a potential to leach into groundwater or to run off into surface water.
  • Apply Sumagic to well-watered vigorously growing plants.
  • Application to media containing pine bark will reduce Sumagic activity.
  • Do not mix Sumagic with pesticides, fertilizers, wetting agents, spreader stickers or other adjuvants.
  • Do not apply Sumagic to any food crops.
  • Do not reuse soil from plants treated with Sumagic.


Sumagic mixes readily with water.

FOLIAR AND SOIL SURFACE APPLICATIONS: Always make sure application equipment is thoroughly clean before mixing. When preparing Sumagic for use as a spray, fill tank to one half full. Shake Sumagic container well before using. Add the recommended amount of Sumagic according to the Rate Conversion Table below. Complete filling the tank.

DRENCH AND BULB DIP APPLICATIONS: Add the recommended amount of Sumagic to the appropriate volume of water for use as a drench or dip solution.


Do not apply directly to water, or to areas where surface water is present or to intertidal areas below the mean high water mark. Do not contaminate water when disposing of equipment washwaters.
