Shortstop 2SC Plant Growth Regulator gallon (128 oz)

Shortstop 2SC is a systemic, xylem-mobile plant growth regulator for trees, shrubs, and landscape plantings. It slows above-ground vegetative growth by inhibiting gibberellin biosynthesis, reducing pruning needs while supporting improved root development, drought tolerance, and overall plant stress management. The label lists use on selected trees, shrubs, utility rights-of-way, urban environments, residential areas, parks, commercial sites, and other non-crop areas.

Features and Benefits

• Systemic plant growth regulator for trees and shrubs
• Contains paclobutrazol to inhibit gibberellin biosynthesis
• Reduces above-ground vegetative growth and extends trimming cycles
• Encourages increased root development and fine root growth
• May improve drought, insect, and disease tolerance
• Produces shorter internodes, thicker leaf cuticles, and darker green foliage
• Can be applied as a basal soil drench or soil injection
• Foliar spray option for growth suppression on labeled shrubs and landscape plants

Where to Use Shortstop 2SC

Use on labeled trees, woody shrubs, and landscape plantings in utility rights-of-way, urban environments, residential areas, parks, commercial landscapes, nurseries, roadsides, fence rows, and other outdoor non-crop areas.

Application Notes

Apply Shortstop 2SC as a basal drench, soil injection, or labeled foliar spray depending on plant type and treatment objective. For tree and shrub soil applications, mix 1 part Shortstop 2SC with 11 parts water. Applications may be made throughout the year when soil is not saturated or frozen. Do not treat trees under 1.5 inches DBH, severely stressed trees, trees used for sugar tapping, or fruit/nut trees that will be harvested within one year. Follow all label rate tables by tree DBH, species, shrub crown volume, and foliar spray species. :contentReference[oaicite:1]{index=1}
