Systemic plant growth regulator that slows above ground vegetative growth - reducing pruning and enhancing fine root hair growth. Shortstop 2SC may now be used for both trees and shrubs. It slows above-ground vegetative growth by inhibiting gibberellin biosynthesis. Results last longer when applied to the soil near the base of the tree or shrub by soil injections or with a basal soil drench. Foliar applications may also be applied to shrubs. Shortstop 2SC benefits your trees and shrubs by redistributing energy to increase root production, altering leaf physiology to reduce water vapor loss, and increasing the production of chlorophyll to aid in the process of photosynthesis.
