DPH Biologicals Scales Production of its RootXCell Biostimulant for Ornamental Growers
April 27, 2023 
To help ornamental growers deliver climate-resilient plants and trees, DPH Biologicals has announced global distribution of RootXCell, a unique biostimulant combining living biologicals with a powerful, well-known plant growth hormone.
RootXCell technology is powered by Indole-3-butyric acid (IBA), a naturally occurring plant hormone that accelerates root development and nutrient absorption, improving plant stress tolerance. DPH Bio is scaling RootXCell as part of its line-up of data-proven and field-verified biologicals developed specifically for nursery and greenhouse growers.
RootXCell is DPH Bio’s latest technology, and plans are in place to scale this product through new regions, crops, and use patterns.
“With RootXCell, T&O professionals have at hand a powerful new tool to combat the increasing climate impacts on turf, trees, and gardens by growing stronger, better-established plants,” says Roberto Werneck, DPH Biologicals’ Senior Vice President of Turf and Ornamentals. “By adding biology to a familiar face like IBA, DPH Biologicals continues to demonstrate our understanding of the solutions most attractive to growers around the world.”
Horticulturalists have been using IBA-based synthetics since the 1930s to root stem cuttings, and it is the active ingredient in most plant propagation media. But unlike other IBA-derived products, adding living biology with IBA allows RootXCell to build a foundation for root growth, providing the below and above-ground support crucial to plant resiliency to abiotic stress.
Studies have shown that when RootXCell is applied at the soil level or root zone, root mass increases up to 30% in most plant species and up to 50% in hardwood plants and trees. But RootXCell also helps plants survive weather extremes, decreasing mortality rates during drought by 60%. In addition, RootXCell helps plants to capture increased levels of nitrogen, phosphorus, potassium, calcium, and magnesium, nutrients critical to healthy plant growth.
In addition to IBA, RootXCell’s industry-leading formulation includes:
- Bacillus amyloliquefaciens, an aggressive Plant Growth Promoting Rhizobacteria (PGPR).
- Mycorrhizae, a fungi that forms a symbiotic relationship with roots, enhancing nutrient and water uptake.
- Cytokinin, plant hormones supporting cell division and budding.
- B-vitamins, essential contributors to plant photosynthesis and respiration.
RootXCell is 100% water dispersible, shelf stable and easy-to-use. The product is in-stock and available through a network of T&O distributors and retailers.
