Plant Growth Regulators<br />

Sumagic<br />

Uniconazole<br />

GROUP 2 – Cell Elongation<br />

Inhibitor<br />

Description: PGR for ornamental containers;<br />

Reduces internode elongation delivering<br />

compact plants<br />

Mode of action: Inhibits gibberellic acid synthesis<br />

Labeled for: Greenhouses, lath houses, shade<br />

houses and containers<br />

Benefits: Darkens colors, increases chlorophyll<br />

content, thicker leaves, stronger stems,<br />

increases water retention and increases number of flowers and size<br />

Plants: Poinsettias, bedding plants, plugs, flowering/foliage crops,<br />

bulbs and woodies<br />

Methods: Foliar spray, drench, bulb, cutting dip and pre-plant soil<br />

application<br />

Precautions: Strongest and longest-lasting plant response<br />

Signal word: Caution; EPA No: 59639-37; REI: 12 hours<br />

Rate: 0.26-19.2 fl oz<br />

per gallon<br />

Topflor<br />

Flurprimidol<br />

GROUP 2 – Cell Elongation<br />

Inhibitor<br />

Description: Reduces internode elongation,<br />

enhances leaf and bloom color, higher<br />

chlorophyll content, thicker leaves and decreases<br />

water loss<br />

Mode of action: Acts as an inhibitor<br />

of enzymes catalyzing the steps in<br />

GA biosynthesis<br />

Labeled for: Nurseries, greenhouses and shade<br />

houses<br />

Benefits: Unique activity range allows<br />

poinsettia growers to control aggressive<br />

to slower growing varieties<br />

Methods: Spray, drench and chemigation; absorbed through foliage,<br />

stems and roots<br />

Plants: Poinsettias, bedding plants, plugs, bulbs, foliage, perennials<br />

and woodies<br />

Precautions: Cultivars, varieties, environmental conditions and<br />

cultural practices influence efficacy; Signal word: Danger<br />

EPA No: 67690-20; REI: 12 hours<br />

Rate: 0.02-6.46 fl oz<br />

per gallon<br />

Agriculture PGR<br />

Falgro – 20 SP<br />

Gibberellic Acid A3<br />

Description: Gibberellin plant growth regulator<br />

soluble powder<br />

Mode of action: Stimulates cell division and<br />

elongation<br />

Labeled for: Vineyards, orchards, groves, farms<br />

etc<br />

Crops: Seedless table grapes, citrus, cherries,<br />

blueberries, strawberries, vegetables,<br />

bermudagrass, pompom mums and statice<br />

Benefits: Cluster elongation, thinning, control<br />

of skin disorders in citrus, hastens artichoke<br />

harvest, promotes early flowering, increased<br />

flower yield<br />

Precautions: Overdosing causes long, spindly, weak stems<br />

Signal Word: Warning<br />

EPA No: 62097-3<br />

Rate: 0.1-5.6 oz per acre<br />

REI: 4 Hours<br />

Florel<br />

Ethephon<br />

Cell Division Inhibitors – Ethylene Generator<br />

Description: Inhibits stem<br />

extension; aborts flowers and<br />

buds; increases branching<br />

Mode of action: Releases<br />

ethylene gas<br />

Labeled for:<br />

Greenhouses, nurseries,<br />

vegetables and<br />

landscapes<br />

Benefits: Hastens ripening<br />

and maturity of fruits;<br />

increases cucurbit<br />

flowering; inhibits<br />

flowering in ground<br />

covers and ornamental<br />

trees<br />

Uses: Maintains vegetative<br />

stock plants and liners; delays flowering of<br />

young plants; eliminates sweetgum fruits;<br />

removes mistletoe<br />

Plants: Ornamentals, trees, shrubs, cucurbits<br />

Precautions: Use within 4 hours of mixing<br />

Signal word: Caution; EPA No: 264-263-829<br />

Rate: 1 pint per 10<br />

gallons for stock<br />

plants; 1 quart per<br />

10 gallons for fruit<br />

elimination<br />

REI: 48 hours<br />

Garden PGR<br />

Tomato & Blossom<br />

Set Spray – RTU<br />

• Ready-to-use plant hormone that<br />

provides “biological grow power” to<br />

promote blossom set, fruit development<br />

and fruit yield<br />

• Tomatoes, beans, cucumbers, peppers<br />

and strawberries will often bear fruit<br />

earlier when treated with Tomato and<br />

Blossom Set Spray<br />

• Just spray flowers and adjacent foliage with<br />

solution until leaves are completely wet<br />

• Repeat as blossoms appear, or at<br />

weekly to two<br />

week intervals<br />

• Hazardous to<br />

humans and<br />
