Shortstop 2SC is a systemic plant growth regulator designed for trees and shrubs. Its active ingredient is 4-triazole-1-ethanol at a concentration of 22.3%. It is used to control excessive vegetative growth by slowing the rate of cell division, which results in shorter internodes, more compact growth, and increased density in foliage. This product can be applied via basal dendral application (soil/root zone) or soil injection. It is effective for managing growth in various settings, including ornamental landscapes, residential areas, and commercial properties. When applied as a basal dendral treatment, it helps manage growth in larger trees, while soil injection is used for smaller trees or specific shrub applications. Users should note that the product is systemic, meaning it is absorbed by the plant. Handling requires specific personal protective equipment (PPE), including long-sleeved shirts, long pants, and chemical-resistant gloves. Avoid contact with eyes and skin. If contact occurs, follow the first aid instructions provided on the label. Do not apply to food or feed crops or trees intended for food/fruit production. Always mix according to the specific rates provided in the application tables based on tree diameter or shrub volume.
