The Basics of ShortStop  (paclobutrazol) slows the growth of trees and woody shrubs at the growing point of the branches (apical meristem). ShortStop holds the growth at approximately 10% of it's normal growth and the control lasts for a minimum of three years.

·      Holds fast growing trees & shrubs in neat form longer

·      Establishes a new client service; treat before trimming is needed

·      Allows the company to increase efficiency and/or clientelle base

 

ShortStop generates secondary benefits in treated trees.  The redirection of energy from growth (elongation in branches) produces drought and pest resistance and enhances root hair growth, creating a healthier plant.

·     Applications are recommended prior to construction near trees or girdling root surgery

·     Positive influence on trees located in compacted soils or “tree coffins” (sidewalk containers)

·     Increases the tree’s longevity in urban settings and in low quality soils

 

The Biology of ShortStop  is able to reduce the plant’s growth by interfering with the production of the hormone, gibberellin.  The product is soil applied, either by soil injection or basal drench, and is water-immiscible (won’t leach from site).  The application can be done anytime of the year, except when the soil is frozen or saturated (heavy rain).
