ShortStop is a systemic plant growth regulator for trees that slows above-ground vegetative growth by inhibiting gibberellin biosynthesis. It is most effective when applied to the soil near the base of the tree via soil injection or basal soil drench.
Benefits of ShortStop applications include:
Redistribution of energy from top growth to root production, reducing pruning needs and improving drought tolerance
Altered leaf physiology, including thicker cuticles, smaller stomata, and increased leaf hairs to reduce water loss and stress
Enhanced root hair growth, improving water and nutrient uptake and reducing stress from construction damage
Reduced gibberellic acid production, resulting in shorter internodes and approximately 80–95% less annual branch growth
Increased abscisic acid production, helping regulate transpiration and drought response
Increased chlorophyll production, supporting energy efficiency and deeper green foliage
