Topflor is the most recent plant growth regulator (PGR) to be introduced to growers of containerized ornamental plants in commercial nurseries, greenhouses, and shadehouses within the U.S. However, while it may be the newest PGR tool domestically, Topflor has been successfully used by European growers for many years to produce some of the world's finest and most outstanding ornamental crops.

The positive attributes of Topflor will allow growers to produce top quality plants resulting in improved marketability of their crop. Today's consumers demand the highest quality plants that are compact, full of vibrant blooms, possess dark green foliage, and will demonstrate outstanding garden performance. Growers now have a PGR tool that provides the ability to grow that "perfect" crop that consumers demand. Some of the many benefits of using Topflor include:

Topflor is active on a wide range of crops, which makes selecting a PGR less complicated
Topflor's unique activity range allows growers to control even the most vigorous plant species while providing the proper amount of control for slower growing crops
Topflor has improved plant uptake vs. other PGR's, which in many cases results in lower application rates required to achieve optimum growth regulation
Topflor is highly active through plant roots, which lends itself to uniform growth regulation and reduced flower delay
European growers have experienced that plants treated with Topflor produce darker blooms and fewer faded blooms
Topflor also strengthens and tones plants, which reduces shipping losses
Dark green foliage is evident in Topflor treated plants

The choice of which PGR to use has just become simplified. Topflor possesses the essential characteristics that a grower needs in order to produce the highest quality plants that maintain optimum size and shape long enough to maximize sell through at retail. Consumers who purchase plants treated with Topflor will be able to enjoy compact plants with outstanding flowers and foliage that will demonstrate outstanding garden performance.
