St. Louis – December 9, 2025 – Growers transplanting vegetables from the greenhouse to the field now have an additional tool to prepare for the unexpected during critical periods of transplant stress. NewLeaf Symbiotics, a biological technology provider and global leader of PPFMs, is launching a specific-to-vegetable transplant (VT) biostimulant for 2026. NewLeaf’s VT Technology, registered Terrasym® VT, has demonstrated notable yield wins in a broad range of specialty crops, including strawberries, tomatoes and cucurbits. VT received California approval for use in late November 2025, making it now available in key U.S. geographies.
“NewLeaf VT technology is a combination of PPFM strains that work together to improve nutrient uptake and mitigate abiotic transplant stress to enhance seedling vigor,” says Aaron Kelley, Chief Commercial Officer of NewLeaf Symbiotics. “These plant benefits result in more fruit being harvested when compared with the grower standard practice as a control in trials.”
Growers using VT have choices in application method, applying via drench prior to transplant or via dripline after transplant. The technology is another proof point demonstrating the power and performance of Pink-Pigmented Facultative Methylotrophs (PPFMs), a class of microbes where NewLeaf is the undisputed global leader. With a library of 12,000 PPFM strains, NewLeaf specifically selects and develops technologies based on each strain’s unique genetic properties. The strains specifically selected and developed into the VT technology for vegetable transplant demonstrated the ability to work symbiotically with these specialty crops.
“VT technology has been tested for more than 8 years in labs, greenhouses, small-plot field trials and on-farm large-scale field trials. NewLeaf puts that time and resource investment into our technology so we can deliver consistent performance for fruit and vegetable transplant production,” says Kelley. “As we awaited critical approvals, like California, we were able to document strong results, including an average yield increase of 2.3 tons/A in processing tomatoes on 20 large scale farm trials from 2022-2024 when compared to grower standard practice.”
NewLeaf’s VT technology is now approved for use in 21 states. Retailers and growers interested in research results or purchasing NewLeaf VT technology for 2026 can reach out to the NewLeaf team at newleafsym.com.
