SePRO Corporation Introduces New Topflor* Granular ornamental growth regulator to suppress plant growth in container nursery plants

Carmel, IN – SePRO Corporation is proud to announce that Topflor* Granular ornamental plant growth regulator has been approved by the U.S. EPA for use on herbaceous and woody ornamental plants grown in containers in greenhouse and outdoor nurseries.  Topflor Granular plant growth regulator contains the active ingredient flurprimidol, which effectively reduces internode elongation through the inhibition of gibberellins biosynthesis, resulting in a more desirable compact ornamental plant.  Topflor Granular is specially formulated on a quick dissolving carrier to provide uniform coverage and quick release of the active ingredient into plant containers following rainfall or irrigation.   

Topflor Granular is labeled for containerized perennial woody and non-woody groundcovers, shrubs and hedge plant materials such as rose, buddleia, azalea, hydrangea, photinia, bougainvillea and holly.  “Research with Topflor has shown it to be very active as a soil media application, and Topflor Granular will provide the grower an easy to apply alternative to drench applications.” said Todd Bunnell Ph.D., SePRO’s Turf & Ornamental Research Manager. 

“SePRO is proud to introduce the first granular ornamental plant growth regulator to the container nursery and greenhouse market,” according to Roger Storey, SePRO’s Vice President, Turf & Ornamental Business.  “Topflor Granular will provide growers a way to extend the selling window of their time sensitive plants, producing a higher quality plant, reducing trimming costs, and on some species, increasing flowering.”  Topflor Granular will join SePRO’s Camelot* O Fungicide and Hachi-Hachi* Insecticide as 2011 new product innovations for the commercial greenhouse and nursery market.
